Pure Tungsten Rod

Pure Tungsten Rod Picture

Tungsten has high melting point, high temperature strength and creep resistance and thermal conductivity, electrical conductivity and electron emission performance are good, than the major. Low expansion coefficient and the lowest pressure of metal vapor. The general way of preparation by powder metallurgy.

Pure tungsten rod application
Tungsten rod with special properties, such as low thermal expansion and good thermal conductivity, sufficient anti-resistive, high elastic modulus. Therefore tungsten rod is widely used in various fields. Such as support lines, import lines, printer needles, various electrodes and quartz furnace, high-speed tools, auto auto products, sputtering target.
