Electroless Nickel Plating
HP also specializes in ENP plating particularly suited to applications that require efficient electrical conductivity and in blending alloys of nickel and phosphorous, including:
High Phosphorus (10% to 13%): superior corrosion protection; most resistant to acidic environments; greater than 65 Rc hardness with post-plate thermal treatment
Medium Phosphorus (5% to 9%): best appearance Low Phosphorus (<5%): highest as-plated surface
Hardness (up to 60 Rc); most resistant to alkaline environments; best solder ability
Electroless nickel can also be rendered non-magnetic, making it the optimal choice for electromagnetic shielding. Electroless nickel can be applied over a variety of substrates including stainless steel, aluminum, copper, brass and many proprietary alloys.
