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
UNS C14415 has good Corrosion Resistanc
CuSn0.15 has a good resistance in in natural and industrial
atmosphere (maritime air too).
Industrial and drinking water, aqueous and alkaline solutions
(not oxidizing), pure water vapour (steam), non oxidizing
acids (without oxygen in solution) and salts, neutral saline
solutions.Material can be heat-treated in reducing atmosphere.
High Performance Copper Alloy Foil for heat-exchanger radiator fin
C14415(EN:CuSn0.15), high performance copper alloy foil, has superior properties of high strength, high corrosion-resistance, high softening temperature. It is an ideal material for making radiator fin.
C14415(EN:CuSn0.15) also can be used for
- Connector pins.
- Transistor components.
- Rectifiers.
- Components for the electrical industry.
- Fuse boxes in automobiles.
- Lead frames for semiconductors.
