Description:

Copper Foil is rolled from pure copper ingots, the process including purifying copper ores, make into copper cathodes, ingoting, rolling, annealing, washing, testing, slitting and packing.

This is high quality copper and has a wide range of applications based on conductivity, corrosion resistance, workability, and beauty.

Application:

Copper-nickel-silicon alloys are found in the electrical/electronic industry and utilise the high strength with the good electrical conductivity,stress relaxation resistance and corrosion resistance of the alloys.

Typical applications include:

Lead frames,Connectors,Fuse clips,Contact springs,Resistance welding electrodes,Current carrying formed parts,Switchgear,Press fit pins,Miniature sockets for surface mount devices,Power distribution frets in automotive junction boxes,Clamps for catenary railway fittings
