Engineering Thermal Properties of Metals, Conductivity, Thermal Expansion, Specific Heat Data Metals in general have high electrical conductivity, high thermal conductivity, and high density. Typically they are malleable and ductile, deforming under stress without cleaving.

The Bessemer and open hearth processes were much more efficient than making steel by the puddling process because they used the carbon in the pig iron as a source of heat. The Bessemer (patented in 1855) and the SiemensMartin (c. 1865) processes greatly reduced the cost of steel .
