TUFRAM®

TUFRAM®

Aluminium protected against wear, corrosion, adhesion and cold welding

What is so special about the sandfish?

What is so special about the sandfish?

Water and dirt have no chance on the skin surface of the sandfish, so it slides easily through abrasive sand. Surfaces with our synergistic layers like TUFRAM® are just as water and dirt repellent with good anti-friction properties.

The process

TUFRAM® is the collective term for a family of surface treatments that transforms an aluminium surface into aluminium oxide. During this process, aluminium crystals grow into a porous layer that remains hygroscopic for a short time and has optimal adhesive properties. The water molecules of the newly formed ceramic oxide layer are replaced by embedded polymers. The result is a steel-hard, self-lubricating plastic-ceramic surface in which the polymer particles are integrated.

  • Characteristics

    TUFRAM® layers protect aluminium components against wear, corrosion, adhesion and cold welding.

    During the various stages of the TUFRAM® process, there are many variables that can be controlled to improve various surface properties. Over the years, AHC Benelux has built up considerable expertise, so that today many different TUFRAM® coating variants can be produced. Each of these variants has unique properties that can meet or be tailored to the needs of each application.

    Depending on the layer variant, the following properties are in the foreground or combined together: chemical resistance, non-stick properties, anti-friction properties, wear protection and corrosion protection, dry lubrication or resistance to UV radiation.

  • Base Materials

    Almost all technically interesting aluminium alloys, whether wrought alloys, cast alloys or die-cast alloys, are suitable for surface treatment with TUFRAM®. It is important that the supplied aluminium components are in a coating-compliant condition. The cleaner the surface, the less effort is required in the pre-treatment of the components.

  • Field of Application

    Some TUFRAM® variants are compliant with the relevant food and consumer goods regulations (FDA, USDA, EC). As a result, they are suitable for applications where components are in direct or indirect contact with food, e.g. in the food industry or in the packaging sector.

    However, the areas of application of TUFRAM® coatings are not limited to these two sectors but can also be found, for example, in the automotive industry, in energy technology (oil and gas), in the semiconductor industry, in the aerospace industry, in the pharmaceutical industry or in the field of pneumatics.
