DURATECH

Nickel Tungsten alloy plating process for hard chrome direct replacement for automotive and mechanical components

pic - au element 1.png

Duratech is a chrome free formulation which produces high abrasion resistance and low stress deposit. The electrolyte produces bright appearance (not as bright as chromium), a user friendly process with no special change to plating sequence and the deposit ratio Nickel-Tungsten is 65-35 with hardness 550HV as plated. This electrolyte has diverse applications such as automotive and mechanical components, hydraulic and pneumatic piston rods and cylinders, mining equipment.</p>
