chemical process
Boric-Sulfuric Acid Anodizing (BSA, Boric acid-sulfuric acid anodizing)
- Improved corrosion resistance and paint adhesion
- High electrical resistance, high hardness, excellent wear resistance
Tartaric Sulfuric Acid Anodizing (TSA, Tin-sulfuric acid anodizing)
- Improved corrosion resistance and paint adhesion
- Suitable for assembly due to slight dimensional changes and suitable for marine climate due to excellent corrosion resistance.
