Leo’s Engineering typically anodizes 6061 and 7075 aluminum alloys. We offer this type of surface coating to feed frames that require a much harder surface than bare metal.
UniformityThe Hardcoat process follows the contour of the part with a uniform build up allowing for very close tolerances and effective coating on unusually shaped parts.
Wear Resistance10× greater than unanodized aluminum. Standard Tabor Testing has shown Hardcoat aluminum in 2× greater than Cyanide Case Hardened Steel.
Hardcoat anodize coating is FDA compliant.
