Description
Brass constitutes a composite primarily composed of copper and zinc. Brass alloys possess the inherent capacity for convenient shaping and are offered in a diverse range of colors. Notably, brass exhibits a notable level of thermal conductivity. Forgeability is a commendable trait of CW612N forging brass alloys. These alloys are provided in rod form.
The subsequent datasheet provides comprehensive insight into the attributes of CW612N brass alloys.
