The most commonly used processing technology of tungsten rod is the forging of tungsten rods, which is know as the smithing tungsten rods, it increases the density of tungsten rods to improve the organizational structure by forging. Tungsten is stable at room temperature, the yellow green protective film is formed on the surface of tungsten when the temperature reaches 400-500 degrees. This is normal, the industry recognized a slight surface oxide film and hammer marks.
The tungsten rod with a diameter of more than 100 mm can not be forged at present, so it is necessary to adopt the sintering method, the surface of the sintered tungsten rod is silver grey.
The above is the tungsten rod processing technology that I introduced. Tungsten rod production requires skilled processing technology and perfect equipment, so as to produce a good quality tungsten rod, we have to look for the regular manufacturers in the purchase of tungsten rod.
