Tungsten Mesh Characteristics:
1. Tungsten is a very hard, dense, silvery-white, lustrous metal that tarnishes in air, forming a protective oxide coating. In powder form tungsten is gray in color.
2. The metal has the highest melting point of all metals, and at temperatures over 1650 ºC also has the highest tensile strength. Pure tungsten is ductile, and tungsten wires, even of a very small diameter, have a very high tensile strength.
3. Tungsten is highly resistant to corrosion. It forms tungstic acid (H2WO4), or wolframic acid from the hydrated oxide (WO3) and its salts are called tungstates, or wolframates.
4. Tungsten is one of the five major refractory metals (metals with very high resistance to heat and wear). The other refractory metals are molybdenum, tantalum, rhenium and niobium.
Tungsten Mesh Chemical resistance:
At relative humidity of under 60 %, tungsten is corrosion-resistant. In moisture air, discoloration starts to occur. However, this is less pronounced than in molybdenum. Even at very high temperatures, glass melts, hydrogen, nitrogen, noble gases, metallic melts and oxide ceramic melts are largely unaggressive to tungsten provided that they do not also contain oxidants.
1. Tungsten has the highest melting point of all the refractory metals, a low coefficient of thermal expansion and a relatively high density.
2. Tungsten's good electrical conductivity and excellent thermal conductivity are further valuable properties.
The mechanical properties of tungsten are similar to those of molybdenum. As in the case of molybdenum, these properties are dependent on the temperature at which they are tested. At 3 420 ºC, tungsten has the highest melting point of all metals. The material's high thermal stability coupled with its high modulus of elasticity give tungsten its high creep resistance.
