Adding small quantities of lanthanum oxide (La₂O₃, 1.0~2.0%) to tungsten will improve its creep resistance and the recrystallization temperature. The machining performance for Lanthanum oxide-doped tungsten (Tungsten Lanthanum Alloy, W-La alloy) is better than pure tungsten. Which makes the Lanthanum oxide doped tungsten (Tungsten Lanthanum Alloy, W-La alloy) an ideal material for ion sources, welding electrodes and contact electrodes.
The regular content is 1.5% of lanthanum oxide for Tungsten Lanthanum Alloy (W-La alloy).
