Tungsten-Lanthanum Alloy

Tungsten-Lanthanum alloy is an alloy composed of antimony trioxide in a tungsten matrix with dispersed particles. The content of antimony trioxide is generally from 0.5% to 2.5% (mass fraction). Tungsten-Lanthanum alloy has a higher recrystallization temperature than pure tungsten and has a longer service life than pure tungsten.

Tungsten-Lanthanum alloy sheets are widely used in various fields. Such as high temperature furnace heat shield and heating body, electric light source parts and electric vacuum devices, ion implantation parts and so on.
