Finishing
Inert nuts can be plated in different finishing according to requests of applications
● Zinc
The most popular plating for the most products , bright and smooth and resistant corrosion
The film thickness is 1～3μm , it improves brightness and wear resistance . it is for the most items .
Reduce roughness of parts and improve brightness . is workable for the most metal parts in industry .
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 .
Usually, 5gm～8gm finish coating thickness and with good dispersibility ,Bright appearance .
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 .
Materials
