Among metals, tungsten has the:
- · highest melting point
- · lowest coefficient of thermal expansion
- · lowest vapor pressure
Other tungsten properties include:
- · high tensile strength
- · high thermal conductivity
- · high resistance to thermal creep
- · high electrical conductivity
- · high resistance to corrosion
- · high modulus of elasticity
Tungsten Carbide has a hardness close to diamond. This makes it a commonly used material for applications requiring high strength and wear resistance.
