J22 alloy strip is an iron-cobalt-vanadium soft magnetic alloy with high saturation magnetic induction intensity. Among the existing soft magnetic materials, this alloy has the highest saturation magnetic induction intensity (2.4T), a high Curie point (980°C), and a saturation magnetostriction coefficient. Maximum (60～100×10-6). Due to the high saturation magnetic induction intensity, when making a motor of the same power, the size can be greatly reduced. When making an electromagnet, it can produce a large attraction force under the same cross-sectional area.

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.
