Polishing
Reduce roughness of parts and improve brightness . is workable for the most metal parts in industry .
Tin
With film thickness 0.13～1.27μm , tin finish with bright surface and good ductility , corrosion resistance , lower melting point ,eco-friendly features .
Brass
Usually , 5gm～8gm finish coating thickness and with good dispersibility , Bright appearance .
Dacromet
This finish is grey color with High corrosion resistance , no hydrogen embrittlement , heat resistance , easy to plated more , eco-friendly etc characteristics .
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 .
