Characteristics: Brass is an alloy composed of the metals copper and zinc. Both elements blend very well, which makes brass a very homogeneous material.
Excellent cold-working properties
Alloy that is most often used for deep-drawing
Good spring properties at the proper strength
Application: Brass is mainly used in the industry for general construction purposes or as resistor material. In addition, it is used in lamination, in the production of heating foils and in etching.
Mark: As required.
