Product Overview
Description
C18200 Chromium copper alloy
Copper alloys are generally used as lead-frame material because of their high electronic conductivity, thermal transfer property, and corrosion resistance. During the manufacturing process of lead frame, copper alloys are bent, coated, and etched. Therefore, precipitates included in copper alloys should be fine enough not to disturb uniform treated surfaces.
