Tungsten-Lanthanum Alloy Plate

  • 鎢鑭合金板（英文名稱：Tungsten Lanthanum Alloy） 鎢鑭合金是在鎢基體中以彌散質(zhì)點(diǎn)存在的三氧化二鑭組成的合金。三氧化二鑭含量一般為0.5%~2.5%(質(zhì)量分?jǐn)?shù))。鎢鑭合金在擁有純鎢特性的同

                    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.
