Electroless Nickel Plating Electrical Conductivity

Heat treatments precipitate phosphorus from the alloy and can increase the conductivity of electroless nickel by 2 to 4 times.

Electroless nickel plating electrical conductivity.

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 formulation of the plating solution can also affect conductivity. Not only are the electrical properties of gold plating desirable but gold plating results in the following other desirable properties. The electrical resistivity and thermal conductivity of high phosphorus en is generally 50 200 micro ohms cm and 0 08 w cm2 k respectively.

They are conductive but not as much as some other metals. Hard chrome and electroless nickel plating aren t typically used for their electrical conductivity attributes. The thermal conductivity of an electroless nickel deposit containing 8 to 9 percent phosphorus is 0 0105 to 0 0135 cal cm sec c. Black nickel is electrolytic nickel plating with a secondary treatment to turn the surface black.

Tests with baths complexed with sodium acetate and with succinic acid showed electrical resistivities of 61 and 804μω cm respectively. Conductive textiles coated with nickel aluminum silver and copper are important types of materials for emi shielding. This plating will provide corrosion resistance and maintain electrical conductivity while reducing reflectivity on the surface. Excellent corrosion resistance excellent solderability ability to withstand high temperatures and superior wear.

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. First developed in the 1940s electroless nickel en plating is used heavily by automotive and aviation for corrosion and wear resistance. The electrical conductivity of nickel is 9 7 10 4 s cm 7 9 26.

Heat treatment can lower the resistance a lot. Nickel electroplating electroplating or surface treatment involves applying a thin layer of metal or metal alloy. Gold plating is applied to provide excellent electrical conductivity for many industries. It is a coating with multi functional properties.

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