ALLOYS

Due to the high market demand we have specialized in the following alloys:

Due to the high flowability and the optimised mould filling capability these alloys are especially suitable for the fitting industry and other complex cast products. Thanks to the process of grain refinement we achieve the best possible homogeneity of the structure. If requested, we can also guarantee you a 100 % polishability.

In consequence of the tightened environmental regulations on the European and American market in the field of sanitary industry we have adapted our production processes and meet therefore the strict tolerance limits.

This alloy is an advancement of normal fine-grained brass for the sanitary industry with an optimised dezincification reaction. All other known characteristics of fine-grain ingot are still fulfilled. Also the drinking water ordinance “TrinkwV 2001” is met through according norm restrictions.

Special brass offer high physical properties. They have a high hardness and tensile strength. Additionally they are very resistant to chemical and atmospherical influences. Generally there are three types of special brass to be distinguished, which have different levels of tensile strength (45 – 60 – 75 kg/mm²), because of their different proportions of alloying elements.
Thanks to technical developments in the recent past, some alloys, which can intensify and improve several characteristics of brass with the help of alloying additions, have been developed.

For the particular casting process adapted brass with optimised analytics and optimised additions.

An older alloy which did not become established until the characteristics of the copper aluminium alloy could be considerably improved by the addition of accompanying elements like ferrous, nickel and manganese.

A special form of bronze with a nickel content up to 18 %. It is prefentially used in the glass industry as it makes high production figures possible during the casting process of glass, due to an optimised heat conduction.

By the addition of tin the hardness of 55 Brinell units (copper) can be increased up to well over 230 Brinell units with a tin constituent of 28 %. However, with higher tin constituents the hardness decreases again. To increase the elongation a small amount of zinc can be added as well.
Leaded gunmetal alloys are easy to cast and to machine, because of their lead content. Their corrosion resistance is higher than the one of “normal” brass.

Besides the presented alloys we naturally also produce alloys according to your individual analysis specifications.

Every shipment containes an enclosed certificate of analysis, which has been determined by spectral analysis.
