Production
Magnetically soft alloys are melted in special metallurgical furnaces using a charge of particular purity and are rolled or forged after cooling. The group of magnetically soft materials includes especially pure ferromagnetic iron, electrical low-carbon (unalloyed and siliconized) steels, low-coercive precision alloys based on iron-nickel, composite powder ferroalloys. They find the widest application in modern industry.
Applications
Production of transformers, radio and electrotechnical equipment, automation systems, telemetry, computer engineering. Manufacturing of microphone cores, transformers, electronic memory components, magnetic cores for operation in sea water, magnetic antennas and parts for electrical machines. Used in innovative technology, precision machine tool engineering, household appliances, precision electronics manufacturing, laser technology, and for metrology equipment.
