Tungsten alloy ignitron is used for engine ignition components. It is usually installed at the nozzle of the flamethrower, which can withstand high temperature. It has a high density, generally above 18.2g/cm3; At 1600 ℃, its thermal expansion coefficient of 4.98 x10-6; And the pollution is low. The maximum internal temperature of gasoline engine reaches 2800K, which requires high temperature resistance of ignition tube material. Tungsten alloy is a good material for high temperature resistance. Even at this temperature, it…
