Fe-based Amorphous Ribbons Antaimo®
After 9 years hard researching and testing, our parent company successfully achieved the good result of Amorphous Ribbons from the 40,000-tons-output production line, which is established with technical guide from Chinese Academy Of Engineering.
As the non-crystalline metallic material, amorphous ribbons is particularly good at soft magnetic and high performance in brazing. The amorphous ribbons will replace the position of silicon steel to be widely used in electric transformer, then the power consumption will be saved 60-70%
Application Field
- Medium frequency transformer cores in heating equipment
- Toroidal gapless cores as SMPS output inductors, differential input inductors
- Toroidal gapless cores as noise preventive chokes in car audio,car navigation
system
- Toroidal gap cores for PFC use in air conditioner, plasma TV set
- High frequency rectangular cut cores as output inductors and transformers in
SMPS,UPS etc.
- Toroidal gapless cores as pulse transformer for driving IGBTs,MOSFETs and GTOs
- Amorphous stators and rotors in high power density variable speed electric
motors and generators
Property and Advantage
- Highest saturate induction among amorphous alloy → Reduce component volume
- Low coercivity → Improve component efficiency
- Low core loss → Reduce device temperature rise
- Variable permeability → Meet the various applications requirement by different core heat treatment
- Excellent stability → Having highest serving temperature of 130oC
