Tungsten copper alloy tungsten needle is an alloy material composed of tungsten and copper elements. It has the characteristics of high melting point, high hardness, low conductivity, etc., and is often used to make electrode materials. This electrode material has good electron emission performance and high temperature strength, and can withstand high current density and high temperature, so it is often used in fields such as electron tubes, arc welding, cutting and arc ignition.
When making tungsten-copper alloy tungsten needles, tungsten and copper 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. Tungsten-copper alloy tungsten needles have good thermal conductivity and high-temperature strength, and can withstand high current density and temperature, so they are often used to make high-efficiency electrode materials.
It should be noted that tungsten-copper alloy tungsten needles are more difficult to process and more expensive, so they are mainly used in high-end fields. At the same time, because copper has good electrical conductivity, you need to pay attention to safety when using it.
