1j22 Product Introduction：
1J22 is a high saturation magnetic induction strength iron cobalt vanadium soft magnetic alloy. Among the existing soft magnetic materials, this alloy has the highest saturation magnetic induction strength (2.4T), a high Curie point (980 ℃), and a maximum saturation magnetostriction coefficient (60-100 × 10-6)。 Due to the high saturation magnetic induction strength, when making an electric motor with the same power, the volume can be greatly reduced. When making an electromagnet, it can generate a large attraction force under the same cross-sectional area. Due to the high Curie point, this alloy can work at higher temperatures where other soft magnetic materials have been completely demagnetized, and maintain good magnetic stability. Due to its large magnetostrictive coefficient, it is extremely suitable for use as a magnetostrictive transducer, with high output energy and high work efficiency. The alloy has a low resistivity (0.27 μ Ω · m), not suitable for use at high frequencies. Due to its high price, easy oxidation, and poor processability, the addition of appropriate amounts of nickel or other elements can improve its processability.
