Pure tungsten rods are produced from tungsten powder, and the purity is usually quite high, up to 99.95%. Tungsten can be processed by forging, drawing, extruding and rolling. Pure tungsten ingots are made from tungsten powder using powder metallurgy technology and are the raw materials for processing tungsten rods.

Our tungsten rods are made of particularly fine-grained material, guaranteeing good machinability.

We emphasize absolute precision during the tungsten rod production process. Thanks to our many years of experience in the field of refractory metals, we can even supply tungsten rods with diameters up to 100 mm. We insist on exceptionally low tolerances on diameter and roundness and guarantee excellent straightness of the bars.

Tungsten rod process: A suitable ingot is forged and drawn multiple times. During the multiple drawing processes, it needs to be repeatedly annealed. If it is not annealed, it may break during drawing. Molds are involved in the process to draw the required diameter. To remove oxides from the surface, the graphite acts as a lubricant and this step also removes it from the surface of the rod. Conventional surface treatment is grinding or finishing to ensure that tolerances and surface roughness are within a good range.

Tungsten rods can be used to make emitting cathodes, high-temperature forming rods, support wires, printer needles, various electrodes, quartz furnace heating elements, etc. Tungsten rods are also used in rockets, satellites, aircraft and ships.
