Iron Based Amorphous Alloy Ribbon
Iron Based Amorphous Alloy Ribbon
Performance characteristics:
Amorphous alloys have the highest saturation magnetic induction intensity - reducing device volume
Low coercivity - improving device efficiency
Low rail loss - reducing device temperature rise
Variable magnetic permeability - meeting different application requirements through different magnetic core heat treatment processes
Good stability - capable of working for 130% of a long time
Application areas:
Medium frequency power transformer magnetic core
Ring shaped uncut magnetic core for smooth filtering output inductance and differential mode input inductance in switching power supplies
Ring shaped uncut magnetic core for noise suppression in car audio systems and choke coils in car navigation systems
Circular notch magnetic core for PFC power factor correction in air conditioning and plasma TVs
High frequency rectangular cut magnetic cores for output inductors and transformers in switch mode power supplies, uninterruptible power supplies, etc
Used for IGBTs Circular notch free magnetic cores for MOSFETs and GTOs pulse transformers
Stator and rotor for high power density variable speed motors and generators
