Grain-oriented hluav taws xob hlau feem ntau muaj silicon qib ntawm 3% (Si: 11Fe). Nws yog ua tiav nyob rau hauv xws li ib txoj kev uas cov khoom zoo yog tsim nyob rau hauv lub dov kev taw qhia, vim yog ib tug nruj tswj (them los ntawm Norman P. Goss) ntawm lub crystal orientation txheeb ze rau daim ntawv. Qhov sib nqus flux ceev yog nce los ntawm 30% nyob rau hauv lub coil dov kev taw qhia, txawm hais tias nws magnetic saturation yog txo los ntawm 5%. Nws yog siv rau lub cores ntawm lub hwj chim thiab faib transformers, txias-kuav los tiag grain-oriented steel feem ntau abbreviated rau CRGO.
