Formula: CuSn
Form: Coil
Material: Tinned Copper Alloy
Commodity: Alloys
Hazard Pictogram:
GHS08
Tinned Copper Alloy Coils (CuSn) are thin foils of copper alloy metal that have been coated with a layer of tin that protects the reactive copper from oxidation and corrosion. They’re available in 123 variations, with foils ranging in thickness, width, length and alloy composition. These foils are valued for their high thermal and electrical conductivity, ductility and solderability. These properties make them ideal for applications like printed circuit boards, electrical shielding, gaskets, shims, battery terminals and more. With our broad selection of sizes and grades, Tinned Copper Alloy Coils offer versatile solutions for electronics, thermal management and other industrial needs.
