High Purity Polished Tungsten Rod

High purity tungsten rod (bar) has high melting point, high strength, high hardness, low thermal expansion rate, low vapor pressure, high temperature performance, small expansion coefficient, etc., which is the most widely used high temperature resistant metal materials. Tungsten is the best choice for high temperature applications. There is no metal in nature that is more resistant to heat than tungsten. Because the melting point of tungsten is 3410 degrees, and at high temperature, high purity tungsten can still maintain a very high tensile strength, so tungsten is the first choice in high temperature industrial applications.
 
Application: high purity tungsten rod (bar) is mainly used in the manufacture of various kinds of cathode, high temperature setting rod, bracket, lead wire, electrode for various industrial equipments.
 
Our company strictly control the smallest diameter and roundness tolerance to ensure that the bar / rod has a good straightness. With advanced production equipment and many years of experience in the field of refractory metals, even the production of 20 mm diameter tungsten bars, it is not a problem for us.
