Lead is highly appreciated in apparatus construction for the chemical industry and primarily for nonferrous metallurgy, thanks to its special properties such as corrosion resistance to highly aggressive media, high electrical conductivity, great density, good malleability and low melting point, as well as the fact that it is particularly easy to repair. In most cases, lead needs a base or structural material because of its relatively low strength.
Examples here are sealing with lead and homogeneous lead coating of steel. In addition, solid lead structures are also used.
