Tufram Basic Hard Anodizing

Reliable coating for wear resistance on aluminum surfaces

Part of our Tufram® family of coatings, Tufram Basic hard anodizing is an electrochemical process that creates a protective oxide layer on aluminum parts, improving corrosion resistance and imparting other desirable surface properties such as lubricity. Since the entire process takes place in a cool electrolyte bath, Tufram Basic hard anodizing protects aluminum parts from any thermal distortion.

A wide range of wrought and cast aluminum alloys can be hard anodized. Process conditions as well as aluminum alloy determine the hard oxide layer’s thickness, surface characteristics and degree of substrate incorporation. Our tight process control is a crucial ingredient in a quality hard anodized coating.

General Magnaplate is ISO 9001:2015 and AS9100:D certified, some of the highest accreditations in the industry for process control. In addition, we employ automated ramping for consistency in each batch. These high standards for process and end product make Tufram Basic the only hard anodizing worthy of the Magnaplate name.

Hard Anodizing

Upgrade Your Coating

While these technical and performance characteristics are already far more plentiful than your average generic coating, applications requiring even more advanced performance should turn to the synergistic members of the Tufram family.

The addition of a polymer and dry lubricants for sealing provides a lower coefficient of friction and superior coating quality. Our synergistic Tufram coatings are uniform, and have better non-stick properties and chemical and corrosion resistance than our Tufram Basic hard anodizing.

Technical Advantages

  • Improved hardness.
  • Low coefficient of friction after lubrication.
  • Over 500 hours salt spray corrosion resistance can typically be achieved.
