Soft Magnetic Precision Alloy 1j50 Permalloy Round Rod/Bar is a high saturation magnetic induction iron cobalt vanadium soft magnetic alloy. Among the existing soft magnetic materials, this alloy has the highest saturation magnetic induction (2.4T), high Curie point (980 ℃), and the maximum saturation magnetostriction coefficient (60-100 × 10-6). Because of the high saturation magnetic induction strength, the size of the motor with the same power can be greatly reduced. When it is used as an electromagnet, it can produce a large attraction force under the same cross-sectional area.

1j50 Bar is a beneficial alloy for magnetic cores in electrical equipment requiring high permeability at high magnetic flux densities. It is also found in tape cores where lowest A.C. losses and high permeability at high inductions are desired.
