Extra finish for parallel pin machining part
Zinc
The most popular plating for the most products , making parts are bright and smooth and resistant corrosion
Nickel
The film thickness is 1～3μm , it improves brightness and wear resistance . it is for the most items .
Tin
With film thickness 0.13～1.27μm , tin finish with bright surface and good ductility ,corrosion resistance ,lower melting point ,eco-friendly features . and is used for electronics .
Brass
Usually, 5gm～8gm finish coating thickness and with good dispersibility ,Bright appearance .
Chrome
Chrome finish is silver white color and the thickness of film is 0．25～0．5μm normally . chrome finish has many practical Features like Bright appearance ,Wear resistance ,Corrosion resistance ,Hard plating film ,Heat resistance ,Application and is applicable for Decorative parts,Various instruments ,gears and shafts etc,Automotive ,fastener and so on .
