Technical specifications
Density, heat capacity of tungsten and coefficient of temperature (linear) expansion as a function of temperature are given below.
| t ° K | Specific gravity g / cm 3 | C [kJ / (kg · deg)] | a [1 / Grad] |
| 300 | 19.25 | 0,1344 | 4.44 |
| 800 | 19.31 | 0,1442 | 4.73 |
| 1200 | 19.29 | 0,152 | 5.07 |
| 1500 | 19.26 | 1.636 | 6.05 |
| 2100 | --- | 1.694 | 6.73 |
| 2700 | 19.18 | 1,860 | 8.4 |
- C is the specific heat
- a — Coefficient of temperature (linear) expansion [1 / degree]
Chemical Resistance
Due to its chemical resistance, it does not interact with nitric, hydrochloric and any other mixture of acids. To force the metal to react with acids, it must be heated, then tungsten is dissolved by «royal vodka» and reacts with chlorine or sulfur.
Tungsten alloys
Tungsten alloys are indifferent at high temperatures in a vacuum, therefore they are used in X-ray machine targets, as well as in the production of armor plates, tool steels, and also for rotary drilling. In the presence of scanty impurities, tungsten carbon becomes incredibly hard. Carbide WC is used in engineering for milling of steel and cermets.
