Tungsten pins, also named tungsten needles or tungsten electrodes, are a typical tungsten product with purity of 99.95%. It has a silver-white appearance, a slender structure, a length of 20mm-1000mm, and a diameter of 0.3mm-10mm. Usually, the product is customized. The pin is mostly made from pure tungsten and sometimes tungsten alloy, with the characteristics of high hardness, greater tensile strength, good wear resistance, excellent ductility, and excellent electrical conductivity. However, if a fine tip is required, it is very…
