The main types of industrial tungsten needles are as follows:
1. Pure tungsten needle: A needle-shaped object made of pure tungsten. It has the characteristics of high melting point, high strength, high hardness, good corrosion resistance and low evaporation rate. It is often used in the manufacture of industrial equipment such as high-temperature furnaces and vacuum furnaces. electrodes and heaters.
2. Tungsten alloy needle: A needle-shaped object obtained by alloying tungsten with other metals. It has higher wear resistance and corrosion resistance and is often used in the manufacture of cutting tools, drill bits, pliers and other tools.
3. Round rod-shaped tungsten needle: A tungsten needle with a slender shape and a metallic surface. It is often used as an argon arc welding electrode. It can generate an arc between the tungsten electrode and the workpiece during welding. The filler metal is fed in from one side. Under the action of arc heat, the filler metal and workpiece melt together to form a weld.
4. Tungsten needle with pointed tip: mainly used for instrument probes, such as digital four-probe tester. This equipment is a multi-purpose comprehensive measurement equipment using the four-probe measurement principle. It is suitable for semiconductor material factories and semiconductor device factories, scientific research units and universities conduct resistance performance testing of semiconductor materials.
