In the photovoltaic field, tungsten wire is generally used as a diamond wire base material for silicon wafer cutting. It has high toughness, high tensile strength, high temperature resistance, corrosion resistance and other characteristics. Compared with traditional high-carbon steel wire, tungsten wire has great potential for wire diameter refinement. At present, the diameter of tungsten wire used in diamond wire saws in the photovoltaic industry is about 25-35μm, which is only half the diameter of an adult hair. The diameter of high-carbon steel wire is usually 30-60μm. Wire diameter refinement can effectively reduce silicon wafer loss, meet the requirements of large-size and thin silicon wafer cutting, and help the photovoltaic industry reduce costs and increase efficiency.
In addition to the photovoltaic field, tungsten wire is also widely used in other high-temperature and precision scenes. For example,
In the lighting field: used as a light source or electrode material in lighting equipment such as incandescent lamps and halogen tungsten lamps.
In the electronics field: used as an electron emission source or cathode material in electronic devices such as vacuum tubes and ray tubes.
In the medical field: used as a micro guide wire or electrode material in interventional medical devices or equipment.
In the industrial field: used as heating elements in heating equipment.
