The term ‘refractory metal’ is used to describe a group of metal elements that have exceptionally high melting points and are resistant to wear, corrosion, and deformation.
Industrial uses of the term refractory metal most often refer to five commonly used elements:
Molybdenum (Mo)
Niobium (Nb)
Rhenium (Re)
Tantalum (Ta)
Tungsten (W)
The identifying feature of refractory metals is their resistance to heat. The five industrial refractory metals all have melting points in excess of 3632°F (2000°C).
Why Do F1 Racing Engines Use Tungsten Alloy Crankshafts? Compared with inexpensive lead, tungsten alloy not only has a higher density (60% higher than lead), but also lower toxicity. Compared with steel, tungsten alloy has twice its density and has the advantages of high hardness, good wear resistance, strong corrosion resistance, high melting point, and high-temperature […]
