Electroless Nickel Plating Electrical Conductivity

Electrodeposited nickel has a value of 0 19 to 0 26 cal cm sec c.

Electroless nickel plating electrical conductivity.

The thermal conductivity of an electroless nickel deposit containing 8 to 9 percent phosphorus is 0 0105 to 0 0135 cal cm sec c. Gold plating is applied to provide excellent electrical conductivity for many industries. Not only are the electrical properties of gold plating desirable but gold plating results in the following other desirable properties. For example 3 p gives a resistance of about 30 micro ohm cm 8 9 p gives a resistance of about 90 110 micro ohm cm.

They are conductive but not as much as some other metals. Heat treatment can lower the resistance a lot. This plating will provide corrosion resistance and maintain electrical conductivity while reducing reflectivity on the surface. Hardness heat hardenability solderability electrical conductivity and abrasion wear and corrosion resistance.

Conductive textiles coated with nickel aluminum silver and copper are important types of materials for emi shielding. The electrical resistivity and thermal conductivity of high phosphorus en is generally 50 200 micro ohms cm and 0 08 w cm2 k respectively. It is a coating with multi functional properties. Electrical thermal conductivity the thermal and electrical properties of electroless nickel coatings will vary with phosphorus content.

The specific resistance of electroless nickel with 6 7 p is about 50 70 micro ohm cm in general the more phosphorus the more resistance. Black nickel is electrolytic nickel plating with a secondary treatment to turn the surface black. Hard chrome and electroless nickel plating aren t typically used for their electrical conductivity attributes. The formulation of the plating solution can also affect conductivity.

Nickel electroplating electroplating or surface treatment involves applying a thin layer of metal or metal alloy. First developed in the 1940s electroless nickel en plating is used heavily by automotive and aviation for corrosion and wear resistance. The purpose is to change the technical or physical properties of the surface of the items being plated such as their electrical conductivity or to improve their durability appearance and performance. The electrical conductivity of nickel is 9 7 10 4 s cm 7 9 26.

There is a difference in electrical conductivity properties. Appearance although appearance is not usually the primary concern in industrial uses it s an added benefit of choosing either hard chrome plating or electroless nickel plating.
