Different Surface Treatments

Different functions are achieved by forming a protective layer on the fastener surface: Zinc plating or Zinc-Nickel alloy plating and Zinc-Alloy coating provide anti-corrosion and rust prevention capabilities; Nickel plating and PVD coatings enhance wear and corrosion resistance; Anodic oxidation provides corrosion resistance, wear resistance, and aesthetic protection for light alloy parts. Meanwhile, it allows for precise control over the Coefficient of Friction (CoF) to meet the requirements of corrosion resistance, wear resistance, and assembly consistency under various working conditions.
