Tungsten pin, also named tungsten needle or tungsten electrode, is 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 easy to bend or break during transportation or using.
These pins can be divided into different kinds of products, such as rod shape or a rod with a sharp tip. Although their characteristics are the same, their applications are different.
