Mumetal / Permalloy 80 ni magnetiki cyane nikel-molybdenum-fer.hamwe na 80% nikel na 15% fer hamwe na 5% bya molybdenum.Ningirakamaro nkibikoresho bya magneti mubikoresho byamashanyarazi na elegitoroniki.Permalloy 80 itanga ubushobozi bwambere kandi ntarengwa hamwe nimbaraga nke zagahato, igihombo gito cya hystereze, igihombo cya eddy-cyubu, hamwe na magnetostriction nkeya ningirakamaro mubikorwa byinganda.
Porogaramu:
• Transformer laminations •Icyerekezo • Kwandika imitwe • Gutandukana no kwibanda ku ngogo • Amplifiers • Indangururamajwi • Ingabo.

Mumetal Shielding Potential
Permalloy ifite imbaraga zo hejuru cyane nimbaraga zo guhatira izina bigatuma iba ibikoresho bikwiye byo gukingira ibikorwa.Kugirango ugere kubintu bifuza gukingira, HyMu 80 ihujwe kugeza 1900oF cyangwa 1040oC nyuma yo gukora inzira.Gufata ubushyuhe bwo hejuru byongera uburyo bwo gukingira no gukingira.
