Tungsten Rod

Product Details:

Tungsten Rod

A tungsten rod is a solid cylindrical bar made from tungsten (W), a metal known for its extremely high melting point, density, and hardness. Tungsten rods are widely used in high-temperature, electrical, and industrial applications.

�� Key Properties

• Highest melting point of all metals: ~3422°C

• High density: 19.3 g/cm³, similar to gold

• Excellent hardness and wear resistance

• Good electrical conductivity

• Low thermal expansion

• Corrosion resistant in most environments (except oxidizing conditions at high temperature)

�� Common Applications

• Filaments for incandescent lamps and electron tubes

• X-ray and cathode ray tube electrodes

• High-temperature furnace components

• Aerospace and military applications (rocket nozzles, counterweights)

• Electrical contacts and electrodes

• Tungsten alloy rods for radiation shielding

�� Standard Specifications

• ASTM B760 / B777 – Tungsten and tungsten alloy rods

• MIL-W-21014 – Military grade specifications for tungsten rods

• Supplied in commercially pure tungsten or tungsten alloys

�� Available Sizes

• Diameter: 1 mm to 50 mm or larger

• Length: 100 mm to 1000 mm+

• Can be supplied drawn, hot-rolled, or sintered depending on application

�� Advantages

• Can operate at extremely high temperatures without softening

• Very wear-resistant and strong

• Maintains dimensional stability in harsh environments

• Compatible with machining, EDM, or grinding processes

If you want, I can create a comparison chart of tungsten vs molybdenum vs copper rods, showing melting point, density, thermal/electrical conductivity, and typical applications, which helps in selecting the right rod for high-temperature or electrical projects.

Do you want me to make that chart?
