Electroless nickel coatings are used to enhance the durability, corrosion resistance and performance of metal components. Unlike traditional plating methods, they provide an even coating across complex shapes without the need for an external electrical current.
Composite Coatings
Composite coatings can be obtained by depositing an underlay of electroless nickel and then a top layer of PTFE or silicon carbide. A composite coating may be deposited for the purpose of obtaining a lubricating action or for increasing the abrasion resistance of the coated part.
Electroless Nickel Boron Coatings
Electroless nickel boron coatings contain a small percentage of boron and are valued for their hardness and wear resistance. They also offer high conductivity, making them suitable for demanding environments.
High Phosphorus Coatings
High phosphorus coatings usually contain between ten and thirteen percent phosphorus and are selected for their corrosion resistance. They are non-magnetic, ductile and can act as a barrier in harsh environments.

Medium Phosphorus Coatings
Medium phosphorus coatings have a phosphorus content in the range of 5-9%. Medium phosphorus coatings have good hardness and corrosion properties and can be used in both acidic and alkaline conditions.
Low Phosphorus Coatings
Low phosphorus coatings typically contain between one and four percent phosphorus and are known for their high hardness and wear resistance. This type of electroless nickel coating performs well in alkaline environments. It is also easy to solder, although it is often significantly more expensive than other variants.
