Our competitive advantage: in addition to high pressure die casting, we also have the permanent mold casting process in-house, so that we can work out the solution with the highest cost-effectiveness for you.
- Permanent mold casting (gravity die casting) is generally used for voluminous components with a comparatively high casting weight and small to medium quantities.
- In contrast, high pressure die casting is particularly suitable for thin-walled components with a high degree of reproduction accuracy and medium to large quantities.
Overview brass alloys
The group of brass materials is formed by alloying pure copper with zinc. Special brasses contain additional alloying elements.

Contrary to the widespread belief that brass can only meet low strength requirements, this alloy group is used for structural parts with medium to high strength. Strengths range from about 380 N/mm² to 750 N/mm² for special brass with aluminum, manganese or iron. In addition, brass can be cast very well, making it suitable for complicated molded parts, and is characterized by good corrosion resistance.
The special brass silicon tombac has very good strength, hardness and elongation values and can be cast extremely economically.
Brass and special brasses are used in almost all areas of the capital goods industry and in mechanical engineering, e.g. as housings, levers, bolts, gear elements and shift forks. Brass materials are also particularly suitable for parts with finished cast gearing (toothed and bevel gears).
Conductive brass is used for higher required mechanical strength combined with good conductivity (electrical, thermal).
