A rocket engine or simply "rocket" is a jet engine that uses only propellant mass for forming its high speed propulsive jet. Rocket engines are reaction engines and obtain thrust in accordance with Newton's third law. Since they need no external material to form their jet, rocket engines can be used for spacecraft propulsion as well as terrestrial uses, such as missiles. Most rocket engines are internal combustion engines, although non combusting forms also exist.

Rocket engines produce thrust by the expulsion of a high-speed fluid exhaust. This fluid is nearly always a gas which is created by high pressure (10-200 bar) combustion of solid or liquid propellants, consisting of fuel and oxidiser components, within a combustion chamber.

Owning to its superior wearing resistance, high melting point, low vapor point and strange hardness, tungsten alloy ignition tubes  are increasingly used for rocket engines.

In rockets, temperatures employed are very often far higher than the melting point of the nozzle and combustion chamber materials, two exceptions are graphite and tungsten (~1200 K for copper) It is important that these materials be prevented from combusting, melting or vaporizing to the point of failure. So they need tungsten alloy ignition tubes.

Here is a new tungsten alloy based aramid fiber fabric that protects users against X-ray and gamma ray radiation, which will provide samples to selected customers for applications such as protective clothing and sheet materials used in areas with high radiation levels.

The new fabric is produced by blending radiation-shielding tungsten particles with high strength para-aramid fiber.

Here are some advantages:
Tungsten alloy based aramid fiber fabric is stronger than polyester despite containing a high concentration of tungsten alloy, which can impair fiber’s mechanical properties.

A high level of radiation shielding from the amount of tungsten blended into the aramid fiber.

Excellent flexibility and workability properties not present in lead plates or concrete used for tungsten alloy radiation shielding.

The tungsten-blended fabric also has a high level of flame resistance compared to regular aramid fabric, making it useful in high-heat working conditions.

1. Tungsten alloy collimator is one of the most effective devices for reducing the radiation levels on a job site;

2. Tungsten alloy collimator also increases the quality of radiography shots by reducing the scattering radiation around  the film;

3. Tungsten alloy collimator can provide a safer operating conditions for radiographers;

4. Tungsten is a more effective shielding material than lead. It is an easy handle, non-licensed and very effective shielding material;

5. Tungsten alloy collimator does not spark, which makes it a ideal material for plant operations.
