Mumetal Shielding peev xwm
Permalloy muaj permeability siab heev thiab nominal coercive quab yuam uas ua rau nws yog ib qho khoom siv rau kev tiv thaiv kev ua haujlwm.Txhawm rau ua tiav cov khoom thaiv kev xav tau, HyMu 80 yog annealed txog 1900oF lossis 1040oC tom qab tsim cov txheej txheem.Annealing ntawm qhov kub siab ua kom cov permeability thiab shielding zog.
