Superior corrosion resistance in alkaline or caustic environments
Good wear resistance
Bright deposit
Compressively stressed

Mid Phosphorus Electroless Nickel

Brightest of all EN deposits
ELV, RoHS compliant
Moderate wear resistance
Moderate corrosion protection. 0.001" thickness gives 96 hours in Neutral Salt Spray
48-52 HRc hardness as plated. Up to 68 HRc after bake to harden

High Phosphorus Electroless Nickel

Excellent corrosion protection. Up to 1000 hours Salt Spray for 0.001" thick coating
Best deposit for heavy build (>0.001")
