Copper Foil UNS C14415 CuSn0.15 CW117C,copper foil tape for radiator fin
We are a professional copper foil,copper film roll supplier and exporter in China.

Our copper foil can be used for radiator fin.

Our copper foil can be used to shield and isolate interference of electromagnetic waves and radio waves,etc and the compound of PBC. It is widely used in printed circuit boards,wire and cable,terminals, electrical appliances,building materials, chemical industry and distillation.

CuSn0.15 is a low Tin (Sn) special alloy that combines low cost with highest conductivity. The total cost for finish products are often equal to brass due to excellent conditions for stamping scrap.
Typical applications are male connectors and fuse boxes.

UNS C14415 has good Electrical conductivity

Electrical conductivity is strongly influenced by chemical composition. A high level of cold deformation and small grain size decrease the electrical conductivity moderately.
Minimum conductivity level can be specified
