Tungsten products
Relevance
This metal with a uniquely high melting point is a technologically complex material. Since its discovery, it has been considered a harmful impurity in ores for almost 100 years. When polymetallic ores were smelted with tungsten, the yield of the finished metal decreased, and tungsten ate it up. It is no coincidence that the name Wolfram means wolfram. Nowadays we can’t do without it in electrical engineering and production of alloys with special properties.
Technical characteristics
Tungsten heads the group of the most refractory metals but carbon is the second most refractory, Under ordinary conditions this metal does not react with any chemical substances and its lattice structure is cubic cubic volumetric centered. The density of this metal is identical to that of gold.
| Characteristics | Identification |
|---|---|
| Coefficient of linear thermal expansion α [1/Hrad] | 43x10−6 |
| Alloy density [g/cm3] | 19,3 |
| Tensile strength kg/mm2 | 35 |
| Specific heat capacity at 20 °C [kJ/(kg-grad)] | 0,134 |
| Thermal conductivity K [W/(m-K) | 300,173 |
