1J50 is a nickel-iron soft magnetic alloy containing about 50% nickel. Its unique structure gives it high permeability and low coercive force, allowing magnetic fields to pass through efficiently while minimizing energy loss. With a density of 8.2 g/cm³ and the ability to function reliably at temperatures up to 500°C, 1J50 provides durability in demanding environments.
Unlike conventional silicon steels, which are often designed for bulk power applications, 1J50 excels in precision components where magnetic accuracy and efficiency are non-negotiable.
