Cu Zn 36 : brass for machining

Brass CuZn36, as its designation indicates, is composed of 36% zinc and 64% copper. Also known as C36000, it is a brass that is easy to cut, weld and machine. With its corrosion resistance, modelling, machinability (machinability rate of 100) and threading qualities, CUZN36 brass is very well suited for high-speed machining operations.


CUZN36 standards

At the international level, the standards are different and CU ZN 36 is referred to in different ways:
