Tungsten Lanthanum Sheet

Tungsten Lanthanum Sheet

Description:Tungsten is a refractory metal with the highest melting point and the lowest expansion coefficient, and is suitable for various environments with extremely high temperature requirements. Tungsten lanthanum alloy is made by adding a small amount of lanthanum oxide (La2O3) to tungsten. The content of lanthanum oxide is generally 0.5%~2.5%, and the conventional content is 1.5% and 0.5%.Tungsten lanthanum sheets have the advantages of high melting point, high temperature stability, good electrical and thermal conductivity, high plasticity and weldability. Compared with pure tungsten, tungsten lanthanum alloy not only improves the strength, high temperature creep resistance and recrystallization temperature of tungsten, but also has its own characteristics, such as superior machinability, ductility and wear resistance.The addition of lanthanum can also greatly reduce the electron work function, which is beneficial to electron emission.

Application:Tungsten lanthanum sheets are ideal materials for ion sources, welding electrodes and contact electrodes. They are widely used in aviation, electronics, electric light sources, semiconductors, metallurgy, chemicals, medicine, vacuum films and lighting industries.Tungsten lanthanum alloy sheets are often used in the production of electric vacuum devices, evaporation boats, cathode ray tube components, power semiconductor devices, internal parts of light bulbs, etc.Tungsten electrodes made of tungsten lanthanum sheets have lower electrode burnout rate, good welding performance, better arc starting performance and higher arc column stability. Such as the anode or cathode of thermionic tubes, electrodes for resistance welding and plasma-coated electrodes.
