Enhanced MP6

RoHS-Compliant, Mid-Phosphorus Electroless Nickel

Technical Data Sheet - Enhanced MP6  

Aelectroless nickel plating enhanced mp6 by anoplate inc near syracuse nynoplate’s ENhanced MP6 offers all the advantages of a mid-phosphorus grade electroless nickel to manufacturers without concern over compliance to stringent environmental regulations (e.g. RoHS, WEEE, ELV) that restrict or ban the presence of intentionally added lead or cadmium typically found in the majority of electroless nickel deposits. With an internationally accredited ISO 14001 Environmental Management System, Anoplate is committed to routinely reducing its environmental footprint – Anoplate’s ENhanced MP6 is the product of that commitment. 



  • Corrosion resistant electroless nickel plating system employing the latest in chemical innovation, coupled with Anoplate’s proprietary plating equipment.
  • Mid-phosphorus composition, typically 7-9% by weight, offering a good blend of corrosion and wear resistance
  • Appealing metallic luster with consistent bright nickel appearance
  • Ultra-smooth deposit with consistently low coefficient of friction
  • Deposits evenly on all surfaces, unlike electroplating baths (see heat sink in photo)
  • Can be thermally treated to increase hardness of the nickel phosphorus alloy to an equivalent hardness of 66 Rockwell C

ENhanced MP6 can be applied to a wide variety of materials, including:

  • Steels
  • Stainless Steels
  • Inconel, Monel, Invar, Kovar
  • Aluminum (picture shown)
  • Brass & Copper

ENhanced MP6 meets and exceeds the following requirements:

  • AMS 2404
  • AMS-C-26074 (formerly MIL-C-26074)
  • ASTM B 733 Type V

Film Thickness & Tolerances

ENhanced MP6 is typically specified for thicknesses in the range of 0.0002”-0.001”, but can easily be applied to thicknesses up to 0.003”. For extreme corrosion applications, it is recommended for deposit thickness greater than 0.001” per surface.

Typical Applications

ENhanced MP6 should be applied where tight tolerances, corrosion resistance, and durability are required. ENhanced MP6 is an excellent solution for the following applications:

  • Turbine engine seals
  • Locomotive brake components
  • Medical diagnostic equipment
  • Injection molds
  • Hydraulic cylinders
