Wear Resistant Products 

Bradken has always been considered at the forefront of supplying quality, abrasion 

resistant products to the market place. Bradken has strived to improve existing 

technologies and develop new products to provide maximum protection for fixed plant 

and mobile equipment against the effects of wear. Our research and development 

has lead to Bradken providing a range of chromium carbide based technologies that 

outperform traditional quench and tempered steels and high alloy castings. 

The diagram below represents a comparison of common wear resistant materials to 

AS3678-250 mild steel. The materials have been tested under the ATSM G65-04 dry 

sand rubber wheel test standard for low stress sliding abrasion. 

The number next to each product represents the factor by which the product will outlast 

AS3678-250 mild steel. For example, Duablock will last 42 times longer then mild steel 

in a similar low stress abrasion situation. The chart is only intended as a guide and does

Duaplate 

Introduction 

Duaplate is a chromium carbide composite cladding, that is fusion bonded to a backing 

material. Duaplate is renowned for being one of the most abrasive resistant surfaces 

available. Duaplate has been proven to outlast quench and tempered steel by up to 10 

times in high abrasion and impact applications. 

The standard backing material for Duaplate is AS3678-250 mild steel, however, this can 

be changed to suit your operating environment. The backing plate acts as a ductile base, 

which allows Duaplate to be formed and shaped without damage to the overlay material. 

The backing plate can also be used for structural support, allowing entire hoppers and 

chutes to be created using only Duaplate. 

Duaplate is available in four different grades to suit a range of operating conditions: 

D60 - Suited for applications involving high abrasion with moderate to 

high impact. 

D80 - Suited for applications involving high abrasion and high impact. 

D90 - Suited for applications involving severe sliding abrasion or fine 

particle abrasion with low impact. 

D100/D100XP - Suited for applications requiring high abrasion resistance at 

elevated temperatures up to 800oC. Duaplate can also be produced with a smooth or polished surface finish to minimise the 

coefficient of friction. This Duaplate smooth overlay is specifically designed to reduce 

material hang up and to maximise flow properties. Duaplate smooth provides a low 

friction solution to your bulk handling problems without the design or wear performance 

penalties.

The Chromium Carbide 

Solution 

There is a common misconception that the higher the hardness 

of a material, the better the wear resistance. Unfortunately, 

this approach does not take into account the differences 

in microstructure, which has a significant impact on wear 

characteristics. Although Duaplate ® has similar bulk hardness 

to abrasion resistant (AR) steels, the wear characteristics of 

Duaplate are vastly superior. 

Duaplate is a clad plate, manufactured by welding an abrasion 

resistant overlay to a steel base. This overlay is in fact a dual 

phase alloy, or composite, consisting of hard chromium 

carbides in a supporting matrix. On the other hand, AR steels 

are single phase alloys consisting of quenched and tempered 

(Q&T) martensite. The final hardness of Q&T steels is a 

function of temperature hence the variety of hardness grades 

available. 

The two graphs below demonstrate how the presence 

of chromium carbides in the matrix is responsible for wear 

resistance and not the bulk hardness of the material. The 

graphs clearly show that as the volume fraction of carbides 

(VFC) increases, the wear resistance increases, whilst the 

hardness has a minimal effect on reducing abrasion loss.

components. In the case of the Duaplate overlay, the presence 

of tough chromium carbides in the matrix allow for enhanced 

wear resistance, whilst the backing plate allows for formability, 

ductility and ease of fabrication. 

The diagram below represents a comparison of common wear

PRODUCTS 

Duaplate is a clad plate manufactured by welding an abrasion 

resistant material to a steel base. The standard base material 

is an impact resistant mild steel. This can be changed to suit 

your operating environment. 

Overlay Material 

The D60 overlay material is an austenitic chromium carbide 

iron that is based on AS2576-2355. The microstructure 

consists of primary M 7 C 3 carbides in a carbide austenite 

eutectic matrix. The high abrasion resistance is a provided 

by the hard chromium carbides that protect the matrix from 

abrasive wear. 

Typical Properties 

Bulk Hardness: 650 HV50 Carbide Hardness: 1500 HV0.5 Volume Fraction Primary Carbides: 30% 

Welding 

Duaplate ® D60 

The base material can be welded with standard mild steel 

or low hydrogen welding consumables with no pre-heating

Cutting, Forming and Fabrication 

Plasma cutting is the recommended method for cutting 

Duaplate. It is preferable to cut Duaplate from the backing 

plate side to ensure a clean edge and to prevent carbide 

contamination. Duaplate can also be easily cold formed into 

almost any shape that mild steel can, by pinch rolls or hydraulic 

press brake. 

The steel backing plate provides Duaplate with structural 

integrity, thus entire structures can be fabricated from 

Duaplate. Bradken has the capabilities to manufacture such 

structures or to supply cut and formed, ready-to-go wear 

liners.

Duaplate ® Smooth 

Duaplate is a well established chromium carbide overlay 

plate, well known for its high abrasion and impact resistance. 

Duaplate is also available in smooth varieties to maximise 

material flow and reduce hang-up. Duaplate Smooth provides 

a low friction solution to your bulk handling problems, without 

the design or wear penalties. 

The smooth surface of Duaplate Smooth is a result of using a 

flux during the overlay process. This smooth finish, along with 

a slightly modified carbide structure, attributes to Duaplate 

Smooth’s low friction properties. Duaplate Smooth is best 

employed in situations where mass flow is critical and hangup 

is a problem, such as in hoppers and load out bins. 

Several independent laboratory tests have been conducted 

to compliment the successful service history of Duaplate 

Smooth. The tests emphasize the shear stress or friction 

generated when a force or normal stress is applied to a bulk 

material against a liner material. The lower the shear stress 

for a given normal stress, the less likely it will be for the bulk 

material to hang up on the particular liner material. The bulk 

materials used these tests are typically regarded as some of 

the worse in terms of their tendency to hang-up.

Duaplate ® Smooth 

As with standard Duaplate, for optimum wear life it is preferable 

to align any Duaplate Smooth liner or fabrication with the weld 

beads perpendicular to the material flow. It should be noted 

that the orientation of the weld beads has a minimal effect 

on the low friction properties of Duaplate Smooth. Smooth 

varieties of the Duaplate D60 and D80 are available through 

the full range of the standard Duaplate overlay thicknesses. 

D90 Smooth is also available, but only as a 6mm overlay. 

These three smooth grades allow Bradken to offer a low 

friction solution to your material handling problems whether it 

is affected by impact or fine particle abrasion. 

The graphs highlight the superior low friction properties 

Duaplate Smooth achieves over mild steel, other clad plate 

and competitor materials. In addition to Duaplate Smooth, 

Duaplate Polished, which has an even lower coefficient of 

friction, can be supplied for extreme bulk material hang-up 

problems, Duaplate Polished is subject to a minimum order 

quantity and some conditions apply. For more information

Introduction 

Bradken’s block products are a composite material comprising of a chromiummolybdenum, 

abrasion resistant, white iron casting, metallurgically bonded to a weldable 

mild steel backing plate. The white iron casting is a superior wear resistant product, 

containing hard chromium carbides, typically 1500HV, supported in a martensitic matrix. 

The mild steel backing plate is vacuum brazed to the white iron casting, giving a true 

metallurgical bond. Other backing plates, such as stainless steel, can also be used to 

suit the operating environment. 

The standard backing plate is machined flat for quick attachment by welding or Bradken 

can supply blocks fitted with studs for easy installation and removal. When welding the 

backing plate to a surface, no pre heating or post heating is required. 

A wide variety of standard blocks are available, adapted for specific applications. 

However, Bradken’s block products can be custom designed to meet any situation 

regardless of size and shape concerns. Bradken can also supply cut and shaped 

blocks to be strategically placed on equipment so that a unique, high performance wear 

package can be created to maximise service life. 

Bradken’s Block products offer superior wear life compared to Q&T bars, manganese 

steel and chrome-molybdenum pearlitic steels.

Bradken’s block products can be strategically placed on 

equipment before it enters service to prolong life in high wear 

locations. They can also be welded onto equipment during 

service to rectify wear in unexpected, localised trouble areas. 

Duablock – wear bars offer excellent protection 

when used as tumble bars or when configured 

to form a rock-box. They are also used to provide 

protection to heavy earth moving machinery. 

Duabutton – blocks are extensively used on 

heavy earth moving equipment, particular on 

mining and construction buckets and shovels. 

Chokblock – bars are unique block products 

that can be formed and welded onto flat or 

curved surfaces. This allows Chokblocks to 

be used on a range of fixed plant and mobile 

equipment such as buckets and chute liners. 

Microledge – blocks are attached to chutes to 

form micro-rock boxes, which virtually eliminates 

wear to the chute structure. 

Skidblock – pads are used extensively to 

provide strategic protection on heavy earth 

moving equipment, particularly on mining and 

construction buckets and shovels. 

Duatrap – liners are used to create a rock-box 

effect on fixed plant applications such as chutes 

and impact walls. 

Grizzlybar – cappings used to protect grizzly 

fingers.

NiHard 

Products 

NiHard is a well-established white iron product alloyed with nickel and chromium to 

give significant abrasion and impact resistant properties. The structure of NiHard is 

composed of iron and chromium carbides, fixed in a matrix rendered martensitic by the 

nickel content. This structure allows NiHard to be utilised in abrasive and high impact 

conditions found throughout the construction, mining, manufacturing and mineral 

processing industries. 

Bradken NiHard products include billets and liner plates that can be made to the 

customers’ specification or supplied from our range of stock sizes. Bradken’s NiHard 

products can be custom designed to meet any situation regardless of any size and shape 

concerns. Bradken can also supply cut and shaped liners to be strategically placed on 

fixed plant equipment so that a unique wear package can be created, maximising wear 

life. This makes NiHard the perfect material for chutes, drop boxes, bin and hopper liners. 

Bradken primarily supplies cast billet and liner plates produced to the NiHard 4 

specifications. However, Bradken can produce billets and liner plates from the following 

alloys on special request:

Duaceramic 

Duaceramic is a new product developed and manufactured in Australia by Bradken. 

Duaceramic combines exceptionally abrasion resistant alumina tiles, imbedded in an 

impact resistant polyurethane elastomer, to provide an outstanding wear resistant 

product. 

The extremely hard ceramic tiles protect equipment from deterioration, whilst the elastic 

properties of the polyurethane dampens any impact. Several different modular alumina 

tile designs are available that are suited for different applications. The hardness of the 

polyurethane is also available in multiple grades to suit specific material and operating 

conditions. 

As one of the hardness materials known, alumina is far superior to steel plate when it 

comes to protection against abrasion. The Duaceramic range of products are specifically 

designed to protect against the most extreme abrasive environments.

PRODUCTS 

Duaceramic ® Liners 

Duaceramic is a new, dynamic product offered by Bradken’s 

Wear Plate and Block. Duaceramic combines hard alumina 

ceramic blocks, chemically and mechanically bonded to an 

impact resistant polyurethane elastomer. Duaceramic is designed 

for use in the most extreme abrasive environments found in the 

mining and mineral processing industries. 

Duaceramic liners are available in a range of standard thicknesses 

and shapes. Duaceramic liners can also be customised to provide 

unique shapes for wear packages. The Duaceramic liners can be 

manufactured using hexagonal alumina blocks for high abrasion 

and medium impact or large rectangular alumina ceramic tiles, 

for extreme abrasion with low impact. 

Duaceramic Features: 

Maximum Resistance To Abrasion: The ceramic blocks used 

in Duaceramic are manufactured from high alumina ceramic to 

provide maximum resistance to abrasion. 

Multidirectional: The Duaceramic liners do not require a specific 

orientation to flow direction. 

Edge Protection: Leading and trailing edges can be included to 

protect the ceramic tiles from severe impact on the edges. 

Noise Reduction: The polyurethane medium not only absorbs 

impact, but also reduces noise caused by bulk material flow. 

Backing Plate: A unique, light weight backing plate can be 

included to provide assistance in the knockout of worn liners. 

Ceramic Locking System: Each ceramic tile used in the 

Duaceramic liners comes with a locking mechanism to prevent 

tile knock out during severe impact. 

Wear Indicators: Duaceramic Liners can be manufactureed to 

indicate when 50% or more of the ceramic has been abraded. 

Unique Chemical Treatment: The ceramic tiles in Duaceramic 

undergo a unique chemical treatment to provide a superior 

polyurethane to ceramic bond strength. 

Customized Liners: Duaceramic can be manufactured into a 

range of complex shapes with angles and bevelled edges. 

Australian made: Duaceramic is a wholly Australian developed 

and manufactured product by Bradken.
