Nickel-tungsten alloy plating

Nickel-tungsten alloy plating, having excellent resistance properties against strong acids, halogen attacks, adhesion at high temperatures, heat, wear, and so on, is now being used as a replacement for chromium plating.

Nickel-tungsten alloy plating : Features (characteristic value)

  • - 20wt% or more tungsten content (Resisting high concentrations of hydrochloric acid, sulfuric acid, hydrofluoric acid, and nitric acid.)
  • - 44wt% tungsten alloy plating (As-plated: Hv600, Heat-treated (700°C): Hv1350, Excels in thermal resistance.)
  • - Thermal resistance: Hv950 maintained at a high temperature of 600°C (Utilized for glass molds subject to continuous use at approximately 600°C.)
