  • 20 Interesting Facts About Tungsten Brian D Colwell

    Tungsten has the highest melting point 6191.6 F or 3422 C, the lowest vapor pressure, and the highest tensile strength of all metals. Tungsten is also extremely dense with a density within 0.36 percent that of gold. Tungsten is one of the five refractory metals. The other metals are niobium, molybdenum, tantalum, and rhenium.Tungsten has the highest melting point 6191.6 F or 3422 C, the lowest vapor pressure, and the highest tensile strength of all metals. Tungsten is also extremely dense with a density within 0.36 percent that of gold. Tungsten is one of the five refractory metals. The other metals are niobium, molybdenum, tantalum, and rhenium.Tungsten in its pure form cannot be used in jewelry. Instead, it is formed into a metal, consisting of approximately 85 tungsten and 15 carbon, nickel or cobalt which is known as tungsten carbide. Because tungsten is very brittle, mixing it with carbon reduces this characteristic, making the metal more durable and easier to work with.
