White Copper Strip​

Overview

White Copper Strip is a copper-based alloy primarily composed of copper (Cu) and nickel (Ni), typically combined with zinc. Some grades may contain trace elements like manganese or iron. This silver-white metallic strip derives its name from its resemblance to silver. Common variants include Zinc White Copper, Nickel White Copper, and Iron White
