Is chrome a poor conductor? BudgetLightForum

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 hand tools like wrenches and sockets -try ...

Best electrically conductive plating for mild steel?

When people say "chrome plating" they most often mean decorative nickel-chrome plating: several heavy layers of nickel plating, followed by a thin flash of chrome plating. The nickel plating might be about 0.001" thick and the chrome about 0.000030" -- so the chrome might be something like 3% of the plating weight, maybe less.
