Tin Coated Copper

Advantages of product:

Tin coated copper is pure copper wire or strip coated with a thin layer of tin on the surface, applied by electroplating or hot-dip methods. The tin layer protects copper from oxidation, improves solderability and corrosion resistance.

LiOA Copper produces tin coated copper from 99.99% pure drawn copper wire, with uniform tin plating, high adhesion, no peeling during bending or drawing.
