The Iron Based Amorphous Ribbon is made by the composition of 80%Fe, 20%Sic and B-metal elements materials and formed by strip-casting technology.
With high permeability, low loss and ideal stability, it can meet modern electronic product's requirements in high frequency, large current, small size and energy saving, and can also replace silicon steel, perm alloy and ferrite in electricity utility and electronic products.

Performance Advantages & Feature
High saturation flux density-- to reduce winding turns, minimize product size
High resistivity, low coercivity--to improve production performance
Low loss(1/3 to 1/5 of silicon sheet)--to cool temperature, improve efficiency
Low excitation--decrease no-load current, and noise
Adjustable permeability--adopt different heat treatment process according to different requirement
High temperature stability--long-term operation under 130° C
All production and manufacture procedures are under strict control.
