Electroless Nickel: Mid Phos 6% - 9%

Electroless Nickel plating is a nickel phosphorus alloy deposit plated by chemical reduction, without applying an external electrical current, onto a suitable substrate. Electroless Nickel provides very uniform, hard, lubricious coatings. The deposit uniformity allows plating of various coating thicknesses on any section of a part exposed to fresh plating solution. Grooves, slots, blind holes, threads, and even the inside of tubing can have the same thickness of coating. As a direct result of the deposit uniformity many post-plate finishing steps such as grinding, can be eliminated, thus lowering overall costs.

General Functional Properties: 

• Corrosion Resistance
• Wear Resistance 
• Hardness 40 RC
• Lubricity
• Solderability and bondability
• Uniformity of deposit regardless of geometries
• Nonmagnetic properties of high phosphorous alloy

Electroless Nickel plating can be covered by the following specifications:
