Tungsten-lanthanum tungsten pin is an alloy material composed of tungsten and lanthanum elements. The chemical symbol of tungsten is W, and the chemical symbol of lanthanum is La. The material made by mixing the two elements in a certain proportion is a tungsten-lanthanum alloy. It has a high melting point.
Tungsten-lanthanum tungsten pin is an alloy material composed of tungsten and lanthanum elements. It has the characteristics of high melting point, high hardness, low conductivity, etc., and is often used to make electrode materials. This kind of electrode can withstand high current density and high temperature, and has good electron emission performance, so it is often used in fields such as electron tubes, arc welding, cutting and arc ignition. When making tungsten-lanthanum alloy electrodes, tungsten and lanthanum elements need to be mixed in a certain proportion, and then sintering, processing, etc. are performed to finally obtain an electrode material with the required shape and performance. It should be noted that lanthanum element has certain radioactivity, so safety needs to be paid attention to when processing and using it.
