Tungsten Alloy Rod in Vacuum Equipment

Tungsten alloy rod is high specific gravity tungsten alloy rod with tungsten (W) as the main matrix and nickel (Ni), iron (Fe), or copper (Cu) as alloying elements, manufactured through powder metallurgy. Featuring high density, high strength, low coefficient of thermal expansion, and good dimensional stability, CTIA’s tungsten alloy rod is suitable for counterweights, mechanical structural components, precision parts, and special functional components in vacuum equipment. Through the complementary properties of tungsten-based materials and alloying elements, tungsten alloy rod meets the requirements of vacuum equipment for materials with high stability and reliability.
