Yttrium Hlau yog siv dav hauv kev ua cov hlau tshwj xeeb, nws ua kom muaj zog ntawm cov hlau alloys xws li Chromium, Aluminium, thiab Magnesium. Yttrium yog ib qho ntawm cov khoom siv los ua cov xim liab hauv CRT TV. Raws li cov hlau, nws yog siv rau ntawm cov electrodes ntawm qee qhov kev ua haujlwm siab. Yttrium kuj tseem siv rau hauv kev tsim cov roj mantles rau propane lanterns los hloov Thorium. Nws kuj yog siv los ua kom muaj zog ntawm Aluminium thiab Magnesium alloys. Qhov sib ntxiv ntawm Yttrium rau alloys feem ntau txhim kho kev ua haujlwm, ntxiv kev tiv thaiv rau high-temperature recrystallization thiab ho txhim khu kev tiv thaiv rau high-kub oxidation. Yttrium Hlau tuaj yeem ua tiav rau ntau yam duab ntawm ingots, daim, xov hlau, foils, slabs, rods, discs thiab hmoov.
