Struers covers the entire range of equipment and consumables for materialographic specimen preparation - from
uncomplicated manual machines to sophisticated computerized preparation solutions. Struers is constantly working on
improving existing products and developing new ones.
Five More Reasons to Choose DiaPro
The DiaPro line of unique diamond suspensions has grown with
five new suspensions, enabling you to increase your applica-
tion areas while experiencing the performance and quality you
expect from Struers. Like all DiaPro suspensions, each one is
optimized for use with a specific Struers grinding or polishing
surface – to cover more applications. Now you can achieve the
results you want – faster, easier and more efficiently.
• Do more with less effort.
• Work faster and easier.
• Clean up quickly.
DiaPro Pan 15
DiaPro Pan 15 µm on MD/DP-Pan should be used as an alterna-
tive to SiC-Paper and cover applications where fine grinding
with DiaPro Allegro/Largo 9 on MD-Largo and DiaPro Plan
on MD-Plan 9 are too aggressive (and may show embedded
grains).
Examples of applications:
• Lead and lead alloys
• Tin and tin alloys
• Fragile composites e.g. carbon or glass fibres in Epoxy
• Fragile and soft electronic components
• Copper and copper alloys
• Others: Paper, various plastics
DiaPro Sat 6
MD/DP-Sat is a universal polishing cloth, and materials of very
different physical properties can be prepared using MD/DP-Sat
because the removal rate is rather high especially with DiaPro
Sat 6 µm.
Examples of applications:
• Electronic components (Wafers, Integrated circuit,
components with large parts of ceramic)
• Many different types of steels.
• Sintered carbides
• Others: all materials where high removal is required during
polishing
DiaPro Mol B 3
DiaPro Mol B 3 on MD/DP-Mol is for polishing hard materials
(>150 HV) or applications where you would usually apply 3 µm
diamonds together with DP-Lubricant Blue or Green.
It is especially suitable for polishing of big unmounted speci-
mens on automatic equipment on MD-Mol APS or for routine
preparation on MD/DP-Mol.
Examples of applications:
Many different types of steels:
DiaPro Dur 1
- Low, medium and high carbon steels
- Low to high alloy steels
- Heat treated steels
DiaPro Dur 1 µm on MD/DP-Dur is used for applications where
MD/DP-Nap with 1 µm diamonds introduces too much relief.
Examples of applications:
• Grey and nodular cast iron
• Many different types of PM (Powder metallurgy)
• Electronic components with soft and thin layers
• Materials where optimum edge retention is required
• Others, soft coatings e.g. not water sensitive galvanized steel
DiaPro Nap ¼
DiaPro Nap ¼ µm is used for materials where oxide polishing
does not give any polishing improvement or too much relief.
Examples of applications:
• For precious materials as Au, Ag, Pt etc.
• Non-ferrous metals
• Electronic components
• Others: various thin coatings

Ultra-Fine Grinding of Hard and Very Hard Materials
Struers introduces two new surfaces to its popular line of MD-Piano plane and fine grinding discs. Now you can prepare hard and
very hard materials faster, easier and with excellent results – using only water. MD-Piano 2000 and 4000 are designed for ultra-
fine grinding of difficult-to-prepare materials, such as ceramics, sintered carbides and tool steels.
These high performing surfaces can replace a fine grinding and a polishing step helping you to speed up preparation time without
compromising specimen quality.
• Less Mess – Easy to Use and Clean
MD-Piano 2000 and 4000 ultra-fine grinding discs are easy to use. No dosing of suspensions and lubricants, no checking of
bottle level and no cleaning is required between steps.
• Faster Preparations, Longer Lifetime
MD-Piano 2000 and 4000 with water cooling help speed up preparation time of hard and very hard materials – and last much
longer than SiC paper. The indicative lifetime corresponds to preparation of 300 specimen holders (6 x ø30mm).
• Outstanding Results
Achieve optimal planeness and edge retention on very hard surfaces.
