- Polishing
Reduce roughness of parts and improve brightness . is workable for the most metal parts in industry .
- Tin finish
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 finish
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 .
