What is Rocket Engine?

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.(http://en.wikipedia.org/wiki/Rocket_engine)

Tungsten Alloy Application for Rocket Engine

Owning to its superior wearing resistance, high melting point, low vapor point and strange hardness, tungsten alloy products is increasingly used for making ignition tubes of 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.
