Alloy magnetach bog : na sheòrsa de alloy le permeability àrd agus coercivity ìosal ann an raon magnetach lag.Tha an seòrsa alloy seo air a chleachdadh gu farsaing ann an gnìomhachas electronics rèidio, ionnstramaid mionaideach, smachd iomallach agus siostaman smachd fèin-ghluasadach.Còmhla, tha e air a chleachdadh sa mhòr-chuid ann an dà thaobh: tionndadh lùtha agus giollachd fiosrachaidh.Tha e na stuth cudromach san eaconamaidh nàiseanta.
Ìre:1J50 (Permalloy), 1J79(Mumetal,HY-MU80), 1J85 (Supermaloy),1J46
Inbhe: GBn 198-1988
Iarrtas: Bidh a’ mhòr-chuid de chruth-atharraichean beaga, cruth-atharraichean cuisle, ath-chraolaidhean, cruth-atharraichean, amplifiers magnetach, bearradh electromagnetic, tachdadh a thathas a’ cleachdadh airson raointean magnetach lag no meadhanach a’ sruthadh cridhe fàinne agus sgiath magnetach.
