Phosphorous Variations in Electroless Nickel Coatings

As experts in electroless nickel plating, us provide the full spectrum of nickel and phosphorous alloys.

Electroless nickel can be alloyed with between 4 and 14% phosphorous. There are three main types of electroless nickel, which are outlined below.

Low phosphorous electroless nickel coatings

Low phosphorous electroless nickel is alloyed with approximately 4% phosphorous. Electroless nickel coatings of this type are typically very hard, have good corrosion protection in alkaline environments and lowest impact on fatigue. Low phosphorous electroless nickel is best for higher temperatures.

Medium phosphorous electroless nickel coatings

Medium phosphorous electroless nickel is alloyed with between 5 to 9% phosphorous. This is the most common type of electroless nickel plating and is typically very bright. Medium phosphorous electroless nickel plating offers moderate corrosion and wear protection.

High phosphorous electroless nickel coatings

High phosphorous electroless nickel is alloyed with 10 to 14% phosphorous. This type of electroless nickel coating has a glass-like structure with the highest level of corrosion protection. It is also non-magnetic.
