CuSn0.15 copper tin alloy copper strip has 88% high conductivity, tensile strength close to 500MMpa, excellent high temperature resistance and corrosion resistance, and is mainly used in large current carrying spring (electrical platform above 800V and 300A), namely high-voltage contact, knife contact, relay box, bus bar, etc.

Bus bars for new energy vehicles above 800V, 300A (CuSn0.15 3.0mm thickness, can be tinned)

Processing characteristics:

CuSn0.15 The alloy is well formed and has good corrosion resistance, suitable for soldering, brazing and brazing.

Under the high temperature condition of 300℃, copper alloy materials with high electrical conductivity and excellent heat resistance include Cu-PHC, Cu-HCP, CuSn0.15. The specific high temperature softening changes are as follows.
