Bismuth

Description

General

Bismuth is mostly produced in the USas by-product of lead, copper, tin, silver and gold winning.The thermal conductivity belongs to the lowest of metals. Remarkably Bi expands 3.32% at solidification. It is with tin, cadmium a low melting metal and used for safety devices. Very poisonous. Available in wire and rods.
