1. Sintered tungsten rods are processed by sintering when the diameter of the tungsten rods produced exceeds 100 mm. The sintered tungsten rods will appear silver-gray;
2. During the production process of tungsten rods, the oxide layer and hammer marks are removed from the forged rod surface through lathes and cylindrical grinders, which can improve the dimensional accuracy and finally give the surface a metallic luster;
3. Tungsten tubes are processed for forging tungsten rods. They are used to conduct gas or liquid in high-temperature environments. The inner diameter of each tungsten tube longer than 100 mm must be above 8 mm.
