Aluminium scandium master alloy AlSc2 ntawm kev muag khoom
Master alloys yog cov khoom semi-tiav lawm, thiab tuaj yeem tsim nyob rau hauv cov duab sib txawv. Lawv yog pre-alloyed sib tov ntawm alloying ntsiab. Lawv kuj tseem hu ua modifiers, hardeners, lossis grain refiners raws li lawv daim ntawv thov. Lawv tau ntxiv rau yaj kom ua tiav qhov tshwm sim tsis zoo. Lawv tau siv los hloov cov hlau ntshiab vim tias lawv siv nyiaj ntau heev thiab txuag lub zog thiab lub sijhawm ntau lawm.
