Purity 99.95% Polished Pure Tungsten Rod
1. Description of Purity 99.95% Polished Pure Tungsen Rod:
Pure tungsten rod have high melting point, high temperature strength and creep resistance, as well as good thermal conductivity, electrical conductivity and electron emission properties, large specific gravity, low expansion coefficient and the lowest metal vapor pressure. It is generally prepared by powder metallurgy.
The unique characteristics of pure tungsten rods are low thermal expansion, good thermal conductivity, adequate electrical resistivity resistance, and high elastic modulus. As a result, tungsten rods are frequently employed in many industries. For instance, filaments, high-speed tools, automobile automatic products, lead-in lines, support lines, printer needles, different electrodes, quartz furnaces, and sputtering targets.
