1、Appearance: The tungsten bar is fine-grained and has a luster rather like that of silver in uniform color. Though the whole bar may slightly curved, the maximum height of the bend should not be more than 15mm.It measures 12×12×510. 2. Application: Purified tungsten bars are used as a material for making special steels and tungsten wire, or used in electric contact points. Tungsten bars with impurities are used to procedure bulb filaments or electron tube filaments, which are guaranteed[...]

The lanthanated tungsten became very popular in the circle of welding in the world soon after it was developed because of its good welding performance .The electric conductivity of Lanthanated Tungsten is most closed to that of 2% Thoriated Tungsten. Welders can easily replace Thoriated Tungsten Electrode with Lanthanated tungsten Electrode at either AC or DC and not have to make any welding program changes. The radioactivity from Thoriated Tungsten can thus be avoided. Another advantage of Lanthanated[...]
