• Hard surface, abrasion-resistant and scratch-proof
• Uniform coat thickness in bores and on threads
• Largely corrosion-resistant
• Minimum friction without lubrication
• Outstanding anti-friction properties
• Very good electrical and thermal insulation properties
• Harmless to foods
• ALTEF® surfaces are easy to clean
• No adherence in narrow areas
• Partial coating
• Coating to tolerances and with dimensional stability

The very hard ALTEF® coating is particularly abrasion-resistant, corrosion resistant and shows a low friction coefficient. The surface of the base material is converted into a ceramic coating in which Teflon® is integrated. Half of the coating thickness penetrates into the base material so that, e. g., at a standard coating thickness of 40 µm an increase of 20 µm develops.
