Mumetal Shielding Potential
Permalloy altissimam permeabilitatem et vim coactivam nominalem habet, quae eam materiam aptam ad operationes protegendas efficit.Ad obtinendas proprietates protegendas desideratas, HyMu 80 usque ad 1900oF vel 1040oC subnectitur, processibus formandis posterior.Annexum temperaturis elevatis permeabilitatem et protegens proprietates auget.
