polished WLa alloy tungsten lanthanum bar for high temperature furnace
The outstanding feature of tungsten lanthanum rod is that they can be batch operated. Among the rod-like metal materials, tungsten lanthanum rod has the highest melting point. In heat, electric conduction and electron emission, it performs very well. The tungsten lanthanum rod is also characterized by high density, low dilatation coefficient and lowest metallic vapor pressure. The density of our tungsten lanthanum rod is ≥ 18.8g/cm3; purity ≥ 99.5%. La2O3 content is normally 1%.
The main application of tungsten rods are:
1. Used as electrodes in the field of rare earth metal industry.
2. For producting electric light source parts and electric vacuum components
3. Used in electric boosting glass kiln electrode
4. Suitable for producing ion implantation parts
5. For producing heating elements and refractory parts in high temperature furnaces
6. Very good interlaminar strength at strong thermal and machanical loadings
For the tungsten lanthanum Rod, following is the normal tungsten lanthanum rod dimension form. For any special dimension, call us please.
