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).
