Is lead poor conductor of electricity
Witryna1 dzień temu · Because stainless steel is a metal alloy, it has the property to conduct electricity but is not as strong as copper or aluminum. Therefore, stainless steel is a poor conductor of electricity. While carbon steel offers a resistivity that is eight times higher than copper, stainless steel has a resistivity that is 40 times higher than copper.
