9um 12um 18um 35um Electronic Soft Pure Copper Foil
Description
RA 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. Our copper ores are imported from South America, which were famous for their copper mining.
This is high quality copper and has a wide range of applications based on conductivity, corrosion resistance, workability, and beauty.
