Tungsten Tube


Fine tubes

Tungsten tube is widely used as high-temperature vessel in sapphire single crystal growth furnace, rare earth metals smelting system, induction furnace heating element, quartz glass smelting system. It is also used more and more in LED industry.

Edgetech Industries LLC provides W Tubes with customized specifications that are used at high temperature.

Specifications of our W tube

Shape Tube
Item No. PM74-T
Purity W≥99.95%
Density 18.3g/cc to 19.2g/cc
Process Sintering or machining from rod
Size 20-640mm OD x 50-1000mm length
Fine tungsten tube 4.75-20mm diameter x 50-300mm length
Surface Grinding, Finish turning

Production process: Isotactic pressing – Intermediate frequency sintering – Machining – Finishing.

Similar with crucible, tube with OD>80mm is made by sintering while small tubing is made by drilling from rod or cylinder. The density for sintered tube will be a bit smaller than forged rods. For 80-100mm OD tubes, which can be made by both way, price for sintered one will be lower.

We are very familiar with our customer’s requirements regarding tungsten product’s quality, therefore we produce and deliver products with high purity and long service life.

Edgetech Industries LLC began offering Tungsten and other refractory metals products years ago. We specialize in providing worldwide customers with all types of Tungsten fabricated products (such as crucible, rod and bar, sheet and plate, etc.), heavy alloy that is mostly used as weights and shielding, composites (such as CuW, AgW) that is used for electrode contacts, and carbide alloy using as tools. Contact us at sales@edgetechmat.com for inquires and more information of tungsten.
