What metal material is the least conductive?

Lead (Pb) is one of the metal materials with relatively poor electrical conductivity. Although lead has some electrical conductivity, its electrical conductivity is relatively low compared to other metal materials.

In addition, among other metal materials, iron (Fe) and tin (Sn) have relatively poor electrical conductivity. Although they still conduct electricity, they have a low conductivity relative to metals such as silver and copper.

It should be noted that the least conductive metal materials still have some conductive properties, and may have other advantages in some applications, such as corrosion resistance, mechanical properties, etc. Therefore, when selecting a conductive material, it is necessary to comprehensively consider the conductive properties of the material and other related requirements.
