Mid Phos EN
Mid Phosphorus Electroless Nickel Plating Process
E-EN 602, a mid phos electoless nickel platingprocess that produces bright mid phosphorus deposits that meet or exceed the standard lead/cadmium medium phosphorus EN baths. Exceptional brightness during the entire bath life and MTO on aluminum is one of its many benefits.
The E-EN 602 process meets MIL 26074B, AMS-2404 B, and AMS 2405 specifications and is in compliance with End of Life of Vehicle (ELV), RoHS, and WEEE initiatives.
E-EN 602 process produces consistent pit-free smooth deposits without lead and cadmium. The process has exceptional stability, consistent plating rates, high tolerance to impurities, and a 1:1 replenishment addition.
Unlike other conventional lead/cadmium based mid phos EN baths the E-EN 602 will maintain its brightness throughout its bath life while most conventional baths will lose their brightness.
