Tungsten rods have superior heat resistance, thermion emission, strength and hardness. Therefore, they are used for various applications, such as discharge electrodes, anchors for electronic tubes, Tungsten Inert Gas (TIG) rods, and probe pins. In addition to ordinary tungsten products, we offer high-purity tungsten products (5-N pure products; PT05).

[ For TIG Welding ]
Tungsten electrode rods for TIG welding are easily startable and are receiving an excellent reputation in stability and durability.
[ For Others ]
Depending on the intended application, you may also request grinding, polishing, machining, bending, brazing and/or other secondary processing treatments. Please contact us for further information.
