    THE KEY FEATURES OF REFRACTORY METALS. The stand out feature of refractory metals is their resistance to heat. All of the five industrial refractory metals have melting points in excess of 3632°F (2000°C) and can maintain their hardness and high strength at elevated temperatures. Refractory metals all are ‘heavy’ with high densities.
