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.
- Uniformity – The 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 Resistance – 10X greater than unanodized aluminum. Standard Tabor Testing has shown Hardcoat aluminum in 2X greater than Cyanide Case Hardened Steel.
- Hardness -65 to 70 Rockwell C, 850 to 900 DPH, harder than hard chrome plate
- Color-Dark Gray to Black
- Coating Thickness-0.002″ average, 0.015″ for salvage purposes on selected alloys
- Dielectric-Hardcoat is non-conductive and will withstand 800 volts per 0.001″ thickness.
- Machining-Hardcoat can be ground, lapped, honed or polished.
- Dyeing-Hardcoat may be dyed most colors but tends to come out dark.
- Sealing-Hardcoat may be Dichromate, Ni-Acetate, hot water, or Teflon sealed.
- Resistivity-between 106 to 1012 Ohm-cm
Hardcoat anodize coating is FDA compliant.
