CHEMETAL USA specializes in the manufacturing of tungsten rod. We offer tungsten rods with diameters ranging from 0.029″ to 5.0” or more. The centerless grinding surface is available for tungsten rod with a diameter less than 1.6″.
The tungsten and tungsten alloy rod products are isostatically pressed and sintered from our high purity tungsten powders to compact billet by powder metallurgy. Following the powder metallurgy is a series of further deformations and heat treatments until the required products are finished. After the production process, the sintered tungsten rods need to be ground, polished, or cleaned based upon the surface condition requested by the customer.
Our tungsten rods are thoroughly checked with NDT (Non-Destructive Testing) in order to identify and eliminate the crack lines, pores and various other defects. In addition, hot isostatic pressing ensures our tungsten rods obtain a high density and fine grain size. These two properties are critical to the components fabricated with the rods since it will help the components have an expected performance and a long service lifespan.
