Electrical conduction properties of nickel plating

Dec 15, 2012There is a difference in electrical conductivity properties. 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. 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. Heat treatment can lower the resistance a lot.

Is chrome a poor conductor?

The electrical conductivity of chrome is usually considered 'good' but usually 5 to 10 times worse than copper. I say usually because chromium can be plated as an alloy to enhance the electrical properties. Usually when we think of chrome, it's hard chrome (like you would see on your car bumper or

Why is stainless steel a poor conductor of electricity?

2 Answers. The reason is that conductivity in metals is high is that metals form a crystal lattice where the outer shell electrons are shared and easily move through the lattice. When the lattice has imperfections the flow of electrons is retarded. Stainless steel is an alloy of iron with up to about 25% chromium
