High Purity Tungsten Metal Needles
High Purity Tungsten Metal Needles Description
High Purity Tungsten Metal Needles are ultra-sharp electrodes used in experimental instruments made from the refractory metal tungsten through powder metallurgy. They are mainly used to score marks on metal surfaces, cut collodion particles and single particle operations, and can also be used as semiconductors. Arc starting electrodes for various industries and various welding processes to improve welding efficiency and quality. High Purity Tungsten Metal Needles have excellent characteristics such as high melting point, high tensile strength, wear resistance, corrosion resistance, high temperature resistance, strong arc ignition ability, high processing performance, long service life, excellent welding performance, etc., depending on the design shape It can be divided into two types: round rod tungsten needle and pointed tungsten needle. Our company can also provide tungsten alloy products such as carbide, tungsten copper and tungsten rhenium. If necessary, please feel free to contact us by email.
