Soft magnetic alloy 1J50 precision alloy K94840 used in weak magnetic fields
High saturation magnetic induction soft magnetic 1J50 ferronickel alloy is a kind of nickel alloy with 45-55% content, showing relatively good initial permeability and high saturation induction strength. The saturation induction value of 1J50 is about 1.55t, and it has the highest saturation induction value in ferronickel alloy. High magnetic properties can be obtained by low temperature annealing. After the final heat treatment, it has obvious cubic crystal structure, its hysteresis loop is almost rectangular, and its remanence is as high as 1.5T.
