Tungsten alloy ignition tubes for rocket engines
Tungsten alloy ignition tube has excellent properties such as high temperature resistance, impact resistance, corrosion resistance, high strength, high density and good ablation resistance, which can meet the high temperature ablation resistance conditions proposed by rocket engines.
Rocket engines, the engines used in rocket thrusters, are jet engines that use compressed, high-performance fuel and produce temperatures that can reach more than 2,000 degrees Celsius during rocket launch. Tungsten alloy ignition tube is used for engine ignition device components, deep into the engine combustion chamber, generally installed in the flamethrower muzzle.
Rocket engine ignition after the instantaneous generation of huge heat, the ignition tube at this time to bear a higher temperature, the ignition tube material put forward higher requirements of high temperature resistance, and the tungsten alloy ignition tube temperature resistance can reach more than 3,000 degrees, fully meet the requirements.
The tungsten alloy can withstand high temperature and maintain its appearance and performance in the fiery working environment. In addition, the density of tungsten alloy is high, generally above 18.2g/cm3;At 1600℃, the thermal expansion coefficient is 4.98x10-6.And low pollution, non-toxic environmental protection. It can be used in the military field to make ammunition, weapon counterweight and radiation proof material.
