Tin Plated Copper & Brass Strips

Overview

Copper and brass strips are tin plated and reflow-processed to improve their properties such as solderability, electric connectivity, and corrosion resistivity. These are highly reliable materials that were reflow processed after being tin-plated to prevent the generation of tin whiskers, which used to be a weakness of tin plating. Their press workability does not change after tin plating and they can be formed into complicated product shapes.

We provide materials with superior appearance properties by using slitting machines exclusive to tin-plating materials.
