OX-HS is a hard anodizing treatment of aluminium in sulphuric acid in conformity with MIL-A-8625 Type III, ISO 10074 and UNI 7796 standards. MAIN HARD ANODIZING PROPERTIES HIGH CORROSION RESISTANCE The compact layer of OX-HS protects the base material from corrosion and brilliantly withstands 336 hours of exposure to salt mist without any corrosive attack. HIGH WEAR RESISTANCE AND HARDNESS The hardness and compactness of the aluminium oxide layer permits obtaining high abrasive and adhesive wear resistance comparable to that of hard chrome. HIGH THICKNESS 40-60µm The high treatment thickness, typically 40-60µm, permits obtaining high duration in aggressive environments. OX-HC BLACK COLOUR VARIANT The OX-HS treatment can be pigmented deep black, thereby making the colour uniform on all aluminium alloys. OX-HS-PTFE LOW-FRICTION VARIANT To lower the friction coefficient and provide anti-adhesion properties, the OX-HS treatment can be impregnated with PTFE nanoparticles.
