HARD ANODIZATION

We offer low- to high-volume hard coat anodizing. Hard anodizing is not the be confused with common anodizing, in which a very thin coating of aluminum oxide is deposited on the surface of the metal. Hard anodizing requires a special process, which produces a dense layer of aluminum oxide both on and in the aluminum surface. The thickness of this coating typically ranges from 1 to 3 mils.

Any hard-anodized surface has a high degree of lubricity. Impregnated with lubricants, such as PTFE Teflon, hard-anodized aluminum surfaces have an even lower coefficient of friction.

We can offer hard coat anodizing in clear, black, red and blue. When ordering hard anodizing from us, we need to be aware of the following information:

  1. Alloy of the aluminium 
  2. Coating thickness
  3. Masking requirements (if any)
  4. Racking instructions (if possible)
