Copper is widely used in electronic and mechanical fields because of its excellent ductility, electrical conductivity and thermal conductivity. Commonly used models are: C11000 (Pure Copper), H62 (Cu-Zn Alloy, Brass), QSn6.5-0.1 (Bronze).
Pure copper has good plasticity, but this will also lead to serious sticking during cutting, chips are not easy to break, and the problem of winding tools, which requires the use of special tools and cutting fluids.
Brass has the best cutting performance because of the lead it contains, but this also leads to more broken chips and easy to pollute the environment.
Tin in bronze will cause hardening during machining and is prone to burrs.
