Amorphous alloys yog hlau thiab alloys uas tsis muaj ntev-ntau thiaj nyob rau hauv lawv cov atomic kev npaj rau. Cov tshuaj hlau los yog hlau muaj kev siv lead ua qauv, thaum lub sij hawm amorphous hlau lov cov thawj kev siv lead ua qauv thiab pib ib tug ntev-lub sij hawm disordered qauv nyob rau hauv lub ceev ceev txias lub xeev, uas yog heev uas zoo sib xws rau cov kua nyob rau hauv cov qauv.

Hlau raws li amorphous hlau yog ib hom ntawm amorphous hlau lug siv nyob rau hauv transformer.Its hlau poob tus nqi yog ib tug thib tsib ntawm cov tsoos silicon steel khoom. Nws yuav hloov tau cov tsoos silicon steel ua faib transformer yuav txuag lub zog ntawm 60-70%, yog tsim nyog ntawm lub zog-txuag cov ntaub ntawv uas. 

Lub amorphous hlau xwb tsis muaj ib tug tsawg dua tsis dua li tsoos silicon steel, tab sis kuj muaj ib tug ntau luv luv npaj cov txheej txheem tshaj lub pob zeb ntais steel, uas zoo heev txog cov nqi ntawm kev npaj.
