Technical Field

[0002] Tungsten bar is a long strip of material made of tungsten metal. It is often used in applications such as electrodes and vacuum equipment. It is often used in electrodes and thermal industries under high temperature environments. The density of tungsten is also very high, about 19.3 grams per cubic centimeter, which is more than twice that of lead. Therefore, tungsten bar has a good sense of weight and quality and is suitable for some applications that require high-density materials. Tungsten has good corrosion resistance and can resist the erosion of most chemicals. Therefore, it is often used to manufacture vacuum equipment and chemical container linings. Tungsten is a good conductive material, so tungsten bar is often used to manufacture electrodes, such as welding electrodes, discharge electrodes, etc. It is also used to manufacture electrodes for electric furnaces and vacuum tubes at high temperatures. Tungsten has very stable chemical properties at room temperature and is not easy to react chemically with other elements. Therefore, it is often used in some applications that require high chemical stability. Tungsten bar forging machine is a device used to process tungsten bars. It can perform hot processing on tungsten bars and perform operations such as drawing to meet the needs of different shapes and sizes.
