Mumetal SuPermalloy (1J85) sheet/STRIP/bar/Ring
Jeneng Dagang Umum: Mumetal, UNS N14080, HY-MU80, Permalloy 80, 1J79, 79НМ,
Mumetal / Permalloy 80 minangka paduan wesi nikel-molybdenum-magnetik banget.kanthi kira-kira 80% nikel lan 15% wesi lan 5% isi molibdenum.Iki migunani minangka bahan inti magnetik ing peralatan listrik lan elektronik.Permalloy 80 nyedhiyakake permeabilitas awal lan maksimal kanthi daya coercive sing kurang, mundhut histeresis sing kurang, kerugian arus eddy sing sithik, lan magnetostriksi sing sithik sing penting kanggo aplikasi industri.
Aplikasi:
• laminasi trafo •Relay • Rekaman Heads • Deflection lan Fokus Yokes • Amplifier • Loudspeaker • Shielding.

Potensi Mumetal Shielding
Permalloy nduweni permeabilitas sing dhuwur banget lan gaya coercive nominal sing ndadekake bahan sing cocok kanggo operasi shielding.Kanggo entuk sifat shielding sing dikarepake, HyMu 80 dianil nganti 1900oF utawa 1040oC sasampunipun proses mbentuk.Annealing ing suhu sing luwih dhuwur nambah permeabilitas lan sifat pelindung.
