ATM zinc aluminum alloy keyboard button

Zinc alloy die casting is a processing form with high production efficiency and one-time molding. It can process structural  parts with complex shapes and is widely used in automobiles and home bathrooms. However, zinc alloys are not resistant to  atmospheric corrosion, and must be coated with copper or chromium protective decorative coatings on their surfaces. The substrate characteristics of the workpiece itself and its special processing form have a significant impact on electroplating.
