Precision Aluminum CNC Lathe Milling Parts Machining

The hot-dip galvanizing of fasteners is to immerse fasteners of carbon steel components into a plating tank of molten zinc with a heat of about 510 degree , so that the iron-zinc alloy on the surface of the fasteners will be converted into passivated zinc, thereby Obtain a surface treatment effect. The price of hot-dip galvanizing of fasteners is higher than that of electroplating, about 1.5 to 2 yuan per kilogram.
