1J79 (Soft magnetic alloy)
(Common Name:nqe 79m4, E11c, malo, permalloy, 79HM)
High permeability mos magnetic alloy
High permeability mos magnetic alloy tsuas yog npib tsib xee puag alloy, cov ntsiab lus nickel yog tshaj 75%, hom alloy no muaj qhov pib permeability siab heev thiab permeability.Feem ntau hu ua permalloy, tseem hu ua thaum ntxov high magnetic conductivity alloy.Lawv txhua tus muaj qhov zoo. kev ua tau zoo, tuaj yeem dov rau hauv nyias strip.Alloy yog tsim rau daim ntawv thov nyob rau hauv lub ac tsis muaj zog magnetic teb.Xws li TV thiab instrumentation nyob rau hauv ntau yam suab transformer, lub siab 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.
