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