Tungsten rods have a wide range of applications in industry, ranging from daily necessities to military applications. The demand is very large. Mature processing technology is required to ensure the production volume of tungsten rods. Below we will follow the polycrystalline tungsten and molybdenum. Learn about the processing technologies of tungsten rods.
The most commonly used processing technology for tungsten rods is forged tungsten rods, also known as forged tungsten rods. Forging is used to increase the density of the tungsten rods and improve the organizational structure. Tungsten is very stable at room temperature, but will change when the temperature reaches 400-500°C. The surface A yellow-green protective film is formed, which is normal. It is recognized by the industry that there are slight oxide films and forging hammer marks on the surface.
There is currently no way to forge tungsten rods with a diameter exceeding 100 mm, so they need to be sintered. The surface of the sintered tungsten rod will be silver-grey.
