How Is A Tungsten Tube Manufactured?​

Typically, it starts with tungsten powder. The powder is compacted through methods like isostatic pressing and then sintered at high temperatures to form a solid structure.

For high - end electronics and aerospace applications, purity levels of 99.95% or higher are often required. In less demanding industrial applications, a purity of around 99% may be sufficient.​

Generally not directly. Tungsten is not a material approved for direct food contact due to potential health risks from heavy metal leaching. However, it may be used in equipment related to food processing in non - contact parts, such as in high - temperature heating elements within industrial ovens used for baking on an industrial scale.​

Compared to many metal tubes, tungsten tubes have a much higher melting point, better high - temperature strength, and superior corrosion resistance in certain high - temperature and corrosive environments. They also have a relatively low thermal expansion coefficient, which means they maintain their shape better under temperature changes.
