electroless nickel & composite nickel plating specialists

Micro Plating Electroless Nickel is an alloy of 10-12% Phosphorus in nickel and is specified wherever a uniform, hard and highly corrosion resistant coating is required. Its high hardness and lack of porosity make it an ideal barrier coating for components exposed to aggressive usage or hostile environments. The as-plated hardness of electroless nickel is approximately 48-52 Rc and can be heat treated to 68-70 Rc for a more wear resistant finish.

Because the coating is deposited "chemically" rather than with electricity, the problems normally associated with electroplating (edge build-up, uneven thickness, no plating in corners and recesses etc.) are typically avoided. Electroless nickel deposits guarantee 100% coverage and are so uniform that the surface finish is normally duplicated and after plate machining or polishing is often eliminated. Threads and other complex shapes also maintain their original geometry after plating.

Micro Plating "high phosphorus electroless nickel" coatings meet or exceed Mil-C-26074 and Aerospace Material Specification 2404 and are recommended where maximum corrosion protection is required. Because of its amorphous structure and lack of porosity at thicknesses above .0004" thick,salt spray tests per ASTM B117 repeatedly show that high phosphorus electroless nickel coatings out perform other electroless nickel deposits with 9% or less phosphorus by over 4 to 1. In some applications the use of Micro Plating High Phosphorus Electroless Nickel allows the substitution of less expensive materials as a low cost alternative to hard to machine or stainless steel alloys.
