Normally, pure tungsten products can be used in the high temperature vacuum environment, so that they can exert their superior high temperature performance. If it is used in air condition under the high temperature of over 400 degrees, tungsten will react with oxygen and produce WO2. Because the melting point of tungsten is 3410 degrees, it can withstand up to 3300 degrees. But its normal working temperature is 1800~2600 degrees.
