Our Anodizing Finish Services
Deliver superior oxide coatings with thickness 5-50μm across aluminum, titanium and magnesium alloys. Our NADCAP-certified facilities provide:
Type II (Sulfuric Acid Anodizing) - for general corrosion resistance
Type III (Hardcoat Anodizing) - for extreme wear applications
Chromic Acid Anodizing - for aerospace components
Color Anodizing - with Pantone-matched dyeing
Teflon-impregnated Anodizing - for low-friction surfaces
What is Anodizing Finish?
An electrochemical process that:
1.Converts metal surface into durable oxide layer
2.Creates porous structure for secondary treatments
3.Enhances both functional and aesthetic properties
