Tungsten Alloy Rocket Ignition Tube

Tungsten alloy rocket ignition tube is a kind of high temperature resistant ignition tube as it has property of ultra-high melting point. Also, such an ignition tube also has high hardness and good wear resistance to meet the high performance requirements of rocket engines on ignition tubes.

When the rocket is launched, the high temperature generated in the nozzle and the combustion chamber is unbearable for ordinary metal materials. Tungsten alloy has a temperature resistance of more than three thousand degrees, so that it can avoid oxidation, melting and evaporation of the rocket ignition tube under high temperature environment. Also, it increases the safety factor of the rocket.

Rocket engine, a type of jet engine, turn the reactant (propellant) in the propellant tank or vehicle into a high-speed jet, to generate thrust due to Newton's third law of motion. Most rocket engines are internal combustion engines. They generate thrust by discharging high-temperature and high-speed gas. Solid or liquid propellants composed of oxidants and fuel are combusted at high pressure of 10-200 bar in the combustion chamber to produce gas. The gas is discharged from the ignition tube, so the ignition tube must be made of high temperature resistant materials. In addition, the space environment also puts forward higher requirements for the material of the ignition tube, and the tungsten alloy rocket ignition tube can meet these requirements.
