Tungsten Rods for Industrial Heating, Welding and Machining Applications

Tungsten rods are high-density refractory metal products designed for extreme temperature and high-stress industrial applications. Manufactured in grades such as W1, W2.1, WAL1, WLa, and WCe, they offer excellent thermal stability, mechanical strength, and electrical conductivity. These rods are widely used in electric boosting glass kilns, welding electrodes, electrical contacts, high-temperature structural components, and precision machining tools such as boring bars. Available in black, alkali washed, ground, or polished finishes, tungsten rods provide flexible processing options depending on application requirements. With a density of approximately 19.1 g/cm³ and exceptional resistance to deformation, they are ideal for demanding environments where conventional metals fail, ensuring long service life, dimensional stability, and reliable performance under extreme conditions.

Note: Special requests will be settled by negotiation between both parties.

While Tungsten Plates and tungsten rods share the same base physical properties (like an extreme melting point of 3,422°C and high density), their cylindrical shape and manufacturing orientation make rods behave differently during fabrication and application.
