Zinc Nickel Plating

Zinc-Nickel has replaced cadmium as the plating standard for preventing corrosion in the harshest environments. Alloying Nickel with Zinc creates a unique composition that will corrode slower than zinc alone. The use of zinc nickel has become increasingly popular in automotive, electronics, aerospace and defense industries due to factors such as extended product warranties, longer life cycle requirements, more stringent safety standards and reduction of environmental impact.
ASTM B841 and AMS2417 is the normal industry standard applied to Zinc Nickel plating.
