Soft Magnetic Alloy para sa Shielding at permalloy core
Malambot na Magnetic Alloy : ay isang uri ng haluang metal na may mataas na permeability at mababang coercivity sa mahinang magnetic field.Ang ganitong uri ng haluang metal ay malawakang ginagamit sa industriya ng radio electronics, precision instrumentation, remote control at automatic control system.Magkasama, pangunahing ginagamit ito sa dalawang aspeto: conversion ng enerhiya at pagproseso ng impormasyon.Ito ay isang mahalagang materyal sa pambansang ekonomiya.
