Tungsten is a hard brittle solid whose color ranges from steel-gray to nearly white. Its melting point is the highest of any metal, 3,410 ° C (6,170 ° F) and its boiling point is about 5,900 ° C (10,600 ° F). Its density is about 19.3 grams per cubic centimeter. Tungsten conducts electrical current very well.
