Electroless Nickel Plating mid Phos (now RoHS compliant)


What is Electroless Nickel Plating mid Phos?

Electroless Nickel is a chemical (non-electrolytic) plating process that deposits a uniform nickel-phosphorus alloy coating onto metal surfaces. Unlike traditional electroplating, it doesn’t require an electrical current — instead, the coating forms through an autocatalytic chemical reaction.

Where Electroless Nickel Plating mid Phos excels

Uniform Coating

Provides even thickness over complex shapes and internal surfaces that is controllable.

Corrosion & Wear Resistance

Excellent protection against rust, abrasion, and chemical attack.

Hardness

Can be heat-treated to increase hardness, improving durability and lifespan.

Appearance

Bright, semi-bright, or matt metallic finish depending on bath chemistry.

Adhesion & Lubricity

Smooth, low-friction surface ideal for sliding or moving components.

Applications

Common in aerospace, automotive, oil & gas, and precision engineering industries.

Eco & Safety Notes

Chromate-free/RoHS-compliant
