Thickness 0.05~2.0mm Soft Magnetic Alloys 1J50 with High Saturation Magnetic Flux Density
A-ONE ALLOY supplies 1J50 soft magnetic cold rolled strip with minimum thickness 0.05mm
1J50 is a widely used soft magnetic alloy in China. It is used where high initial permeability, maximum permeability, and low core loss is needed.
Density: 8.2g/cm3
Curie point: 500°C
Saturation magnetostriction: 25 ppm
Applications
Transformer cores, highly efficient motors, shielding, and specialized electronic devices, such as LF power transducers, chokes, relay parts, solenoids & oscillators.
Chemical composition

| Weight(%) | 0.03 max. | 0.020 max. | 0.020 max. | 0.20 max. | 0.30~0.60 | 0.15~0.30 | 49.0~51.0 | Balance |
Heat treatment
1100°C~1180°C, held for 3~6 hours, cooled to 600°C at a speed below 200°C/h , then cooled to below 300°C at a speed of no less than 400°C/h. Take out from furnace.
The parts heat treated should be handled with care, no vibration, no squeezing, no impacting. Or the magnetic properties will be worse.
