Zinc Alloy: Zinc Alloy (锌合金)
A low-melting alloy based on zinc with small additions of aluminium, copper and magnesium, used for die-cast slider bodies. It flows well into thin moulds, giving accurate shapes and fine detail at high production rates. Porosity, surface defects and dimensional stability are controlled by die design and process parameters. Zinc alloy sliders are polished and plated, and plating adhesion is tested to prevent blistering and peeling.
