Description: Description Product name: high-purity tungsten wire, electrode wire, white tungsten wire, black tungsten wire Purity: W≥99% Basic knowledge of tungsten wire: Tungsten wire, a thin wire made by forging and drawing a tungsten bar. Tungsten filaments are mainly use in electric light sources such as incandescent lamps and halogen lamps. The resistivity of tungsten wire is 5.3*10^-8. Tungsten has a high melting point, high resistivity, good strength, and low vapor pressure. It is a good material for making incandescent filaments among all pure metals. But tungsten is hard and brittle, and it is difficult to process. When the current passes through the tungsten wire and is heated to a certain temperature, the resistance value of the tungsten wire also increases to a certain value (generally, the resistance value of the metal wire increases as the temperature rises). The resistance of this object should be 1370°C-2000°C at room temperature, but the resistance value will change when the length of the cross-sectional area of the tungsten wire changes. Notice: 1. Due to manual measurement, please allow a slight deviation in size. 2. Due to the influence of light and display brightness, the color tone of the photo may be slightly different from the actual project.
