1. PlAte: en Aw - 5059 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.

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. ASSet teSt This test according to ASTM G66 / LAA 140 provides a reliable prediction of the exfoliation corrosion behavior of 5XXX alloys. Materials tested: Alustar EN AW - 5059 and EN AW - 5083 before and after welding. (MIG-welded with filler alloy AL 5183). 3 separate tests were conducted: 1) the results after: > 24 hours immersion in the prescribed chemical test solution at 65°C.
