Application:
Tungsten alloy has good radiation shielding effect, so tungsten alloy tubes can be used for shielding needle tubes in medical treatment; the engine used in rocket thrusters is a jet engine that uses compressed high-performance fuel, which is used when the rocket is launched. The temperature generated can reach thousands of degrees.
Pure Tungsten Tube is a metal material with extremely high temperature resistance, so it is used in rocket engines as lining parts and ignition tube components.
Tungsten tube characteristics:
1. The purity of tantalum and tungsten tubes is very high, generally above 99.95%;
2. Density is above 18.2g/cm3;
3. The recommended working temperature should be lower than 2500℃;
4. Black tungsten tube is 0.2965 at 2027℃;
5. At 1600℃, its thermal expansion coefficient is 4.98x10-6;
6. The specific heat capacity at 1400°C is 0.16J/g. ℃.
7. Tungsten tubes have lower pollution.
Tungsten Tube Production Process:
Isostatic pressing----medium frequency sintering----machining----finished tungsten tube
