Characteristic
The soft magnetic alloy precision 49K2 °F (49K2FA-In, EP207) is used for the manufacture of magnets, pole cores, tips, solenoids. Produced in the form of hot-rolled sheet, cold-rolled strip and wire, wrought circle. It is the magnetic material. According to GOST 693−74 19 induction coercive force is not more than 4 kA / m. Magnetized to saturation in weak fields, due to the presence of cobalt in the composition. Such alloys with good permeability and the minimum coercive force are used for the manufacture of transformers, electronic and electrical equipment, automation systems and remote measuring equipment.
Production
Soft magnetic alloys are melted on the basis of high-purity iron, ferromagnetic, low-carbon steels alloyed and silicon. The basis of low coercitive precision alloys are iron and nickel, ferro-alloys, powder composites. Melting occurs in the special metallurgical furnaces using ultrapure batch, after cooling the ingots are subjected to pull the shoes or rental.
application
Production of transformers, memory components computers cores microphones, magnetic cores, designed to work in a marine environment, magnetic antenna, and so on. N. They are used in the field of innovative technologies, precision machine tools for the production of precision electronic devices, home appliances, laser optics, in the production of metrological art.
