Hard Anodizing Services: Type III Wear-Resistant Coatings for Aluminum

Standard anodizing makes aluminum look good. Hard anodizing services—Type III, or hardcoat—make it tough. By running the electrolyte near freezing at high current density, hardcoat grows a dense ceramic oxide (up to 100 µm) that reaches 400–600 HV, resists wear and corrosion, and even insulates electrically. For sliding, reciprocating, or abrasive aluminum parts, it is […]
