Tungsten Tube
Simple introduction:
With special equipments, Zhengzhou Jinxing Co., Ltd can precisely provide tungsten tubes with different specifications, which may reflect the real performance of tungsten tube.
Tungsten composition is more than 99.95%.
The crystal structure of tungsten tube is compact.
Zhengzhou Jinxing Co., Ltd offers high density tungsten tube. Tungsten tube appears silver gray metallic luster. The purity of tungsten tube is not smaller than 99.95%.
We are able to provide sintered tungsten tube and machined tungsten tube.
Tungsten tube is mainly used as thermocouple protection tube in the high temperature furnace and support in sapphire single crystal furnace and high temperature sintering furnace.
Features and applications of tungsten tube:
We have tungsten alloy tube and tungsten seamless thin- wall tube . Tungsten alloy tube and tungsten seamless thin-wall tube has high melting temperature, high strength, good thermal conductivity and spalling resistance. Tungsten alloy tube and tungsten seamless thin-wall tube can be used as the parts of electron tubes and the heating elements of high temperature furnace. They also can be made into tungsten wedding rings.The highest temperature in service can be up to 3000℃.
The possible interal injuries of tungsten tube such as porosity, slag and cracks are doubly strictly inspected with eddy current and ultrasonic equipments by us to ensure the quality of tungsten tube.
