1j79 Ni79mo4 E11c Malloy Permalloy 79hm Nickel Mos Sib Nqus Alloy Round Bar / Rods / Hlau Nqe Ib Kg
1J79 (Soft magnetic alloy)
(Common Name:nqe 79m4, E11c, malo, permalloy, 79HM)
High permeability mos magnetic alloy
High permeability mos magnetic alloy mas npib tsib xee puag alloy, nickel cov ntsiab lus yog tshaj 75%, hom alloy no muaj lub siab heev pib permeability thiab permeability.Often hu ua permalloy, kuj hu ua thaum ntxov high magnetic conductivity alloy.Lawv tag nrho cov muaj kev ua tau zoo, yuav dov mus rau hauv nyias strip.Alloy yog haum rau daim ntawv thov nyob rau hauv lub ac ntau yam suab paj nruag thiab suab paj nruag. Qhov tseeb choj transformer, transformer, sib nqus shielding, magnetic amplifier, magnetic modulator, lub taub hau, choke, precision hluav taws xob meter ntawm daim thiab daim, thiab lwm yam
1J79 dav siv nyob rau hauv xov tooj cua-electronic kev lag luam, precision instruments, chaw taws teeb tswj thiab tsis siv neeg tswj system.
