hAmel metAAl
Hamel metaal has been a supplier to Dutch industry for more than 70 years as
a stock-holding wholesaler of ferrous and non-ferrous metals. Hamel metaal has
an extensive range of stock in copper, brass, bronze, aluminium, stainless steel,
steel and plastic. In addition, a special supply programme has been developed for
the ship and luxury yacht-building industry, including (Alustar) shipbuilding plates
and profiles, cunifer, duplex and high-grade metals. All products can be customised
and delivered exactly to your specifications.
Hamel metaal provides fast delivery according to any required certification
(EN-10204-2.2, 3.1, 3.2, Germanischer Lloyd, Lloyd’s Register, DNV, RINA etc.)
We are pleased to present our aluminium programme for the luxury yacht and
shipbuilding industries.
This brochure covers the following items:
1. Alustar ® > Product range, chemical composition, mechanical properties,
corrosion resistance and welding
2. Other plate > Product range, chemical composition, mechanical properties
3. Profiles > Product range, special profiles
4. Processing > The various processing options for plate and profile
5. Certification > Information on the various certification documents
Alustar ® was originally developed out of catamaran building in New Zealand and Australia. Due to the unique composition of
this new alloy EN AW - 5059, it is possible to construct stronger and yet lighter (approx. 20%) than with other comparable
aluminium alloys available on the market, such as EN AW - 5083. In addition, this alloy is considerably stronger after welding
(up to approx. 28%) and has a very high corrosion resistance combined with higher ductility.
Alustar ® has also since found its way into the sailing and luxury yacht building industry. Because of the high final strength
after welding and the good deformability, it is possible to design even more innovative and efficient hulls, which in turn have
a positive influence on the speed and form of a (sailing) yacht as well as fuel consumption.
Alustar ® is ideally suited for the construction of ferryboats and other vehicles for which the weight of the construction must be kept
to a minimum. This allows one to remain competitive with other forms of transport and tunnel links. By making use of thinner
material, it is possible to achieve large savings on fuel costs as well as higher speeds by retaining the strength of thicker variants.
Alustar ® is also used in the defence industry for its strong ballistic properties.

COrrOSiOn reSiStAnCe
The corrosive behaviour of aluminium alloys is influenced by the electrochemical processes of the intermetallic bonds. More
magnesium means a stronger material, but raising the magnesium content has a negative effect on corrosion resistance. The cause
of this lies in the unwanted intermetallic bonds that form, in particular, on the grain boundaries in the material. In order to counter
this effect, a quantity of zinc is added, which increases the corrosion resistance and retains the desired strength. This means (in
combination with a production process especially intended for this alloy) that Alustar ® has combined the unique properties of various
alloys. The photographs below and on the following page show the differences between the corrosion resistance of Alustar ® and
EN AW - 5083. The specific test methods are noted alongside the illustrations.

Alustar ® can best be welded using the filler wire alloy mentioned below. The specially developed alloy ensures that the corrosion
resistance and strength in the weld and the area immediately around the weld are not negatively influenced.

The hardness of the weld and the heat-affected zone is shown in diagram 1 on the following
page. The differences in the values between EN AW - 5059 and EN AW - 5083 are shown here.
The values are shown based on a measurement taken from the centre of the weld. It can clearly be
seen that Alustar ® exhibits significantly higher values than the conventional EN AW - 5083 alloy.

5. CertiFiCAtiOn
All materials are available with various certificates, from a 2.2 factory certificate to a
3.2 certificate. If a product has not been certified according to your required authority, we
can have this approval carried out for you by qualified bodies. Generally, a 3.1 certificate is
available for all plates, bars and profiles. A 3.2 certificate is available for various plates and
profiles as standard, depending on the required inspection authority. Below is a brief
explanation of the significance of the various inspection documents.
2.2 FACtOry inSPeCtiOn CertiFiCAte
This document normally only shows a chemical analysis of the product and sometimes a few
mechanical values. These results come from random measurements taken during production
in the factory and have relationship to the material that is ultimately delivered. There is no
direct relationship between the supplied product and the inspection document in the form
of stamps, etc. The document is declared valid by the producer (and signed).
3.1 inSPeCtiOn rePOrt
This document shows test results prescribed in the product standard from the party
(batch/production run) that supplies the final material. There is a direct relationship
between the product and the document. The relationship is guaranteed by a stamp/
paint marks/labels or something similar. An independent authorised controller in the
factory signs the inspection document. This is usually somebody who works in
quality management.
3.2 inSPeCtiOn rePOrt
As for a 3.1 certificate, but with the signature of an inspection body (e.g. Lloyds’DNV/ABS)
designated by the purchaser. This can be done directly during production in the factory (3.2),
or afterwards through so-called external approval (3.1 with supplemental inspection 3.2).
The controller of the inspection body is mostly present during sampling and/or testing.
The document is often given a cover page that is signed by the controller and refers to
the 3.1 document prepared and attached by the factory.
