1j85 alloyis mainly used in the electric power field to manufacture magnetic cores and iron cores in electrical equipment such as transformers, mutual inductors, and relays. Its excellent soft magnetic properties can effectively improve the efficiency of equipment and reduce energy consumption.
1j85 alloyis widely used in the manufacture of various electronic components, such as inductors, transformers, chokes, etc. Its high magnetic permeability and low coercivity can ensure the stability and reliability of electronic components during high-speed operation while reducing electromagnetic interference.
1j85 alloyis used to manufacture various high-frequency devices, such as filters, common mode chokes, etc. Its excellent frequency response and stable magnetic properties ensure the normal operation of communication equipment.
The manufacturing process of stainless steel and alloys involves multiple steps to transform raw materials into flat,rectangular sheets or plates made of stainless steel and alloys. Here are a few key steps for stainless steel and alloys:
Molten stainless steel and alloys are cast into large ingots or billets through a casting process.
During the hot rolling process,the thickness of the steel ingot is gradually reduced and elongated to form long strips or coils.
Annealing involves heating stainless steel and alloys to a specific temperature and then slowly cooling it.
Cold rolling is carried out through rolling mills to reduce thickness to meet customer specifications.
