Type III Hard anodizing is used when an increased wear and abrasion-resistant coating is needed. The aluminum oxide coating is thicker than regular anodizing, which gives the metal surface additional protection. Parts can be processed at lower temperatures, but increased electrical flow is required.
Base metal substrate
- Provides extreme abrasion resistance in coatings having .0005" to .002" thicknesses.
- Provides lubricity hard anodize aluminum oxide abrasion resistant surface.
- Provides excellent corrosion resistance.
- Can be color dyed. Pending the alloy, the natural color is charcoal gray to slightly green hue, with no seal.
- Can be Teflon impregnated.
- Hard Anodize aluminum oxide coating functions and has the feature of being an electrical insulator.
What are the attributes / characteristics of Hardcoat Anodize?
- Increased abrasion resistance (best when unsealed)
- Increased wear resistance.
- Increased corrosion resistance (best when sealed)
- Improved aesthetics (see effect)
- Dielectric properties (coating is an electrical insulator)
