Iron-based Amorphous Alloy Ribbon

 

With a random atomic structure, the crystal anisotropy is not formed in amorphous alloy, so the alloy has an excellent soft magnetic property and the magnetic property of the alloy can be widely adjusted by a heat treatment process.

Amorphous alloy is a new type of energy saving material produced by rapid solidification technology, being cooled from molten alloy at a rate of nearly million degrees per second. It has high permeability and low core loss because of the unique long-range disordered atomic structure, which is completely different from that of crystals. Amorphous alloy is widely used in the fields of distribution transformers, inductors, motor stators and sensors, taking the advantage of significantly improving device efficiency and reducing energy consumption.

 

 

● IF power transformer core

● Annular non-cut core for the switching power supply smoothing filter output inductor, differential mode input inductor

● Annular non-cut core for car audio noise suppression and car navigation system choking coil

● Annular cut core for PFC power factor correction in air conditioning and plasma TV

● High-frequency rectangular cutting core for output inductors and transformers of switching power supplies and uninterruptible power supplies

● Annular non-cut core of IGBTs, MOSFETs and GTOs pulse transformers

● Stator and rotor of high power density variable speed motor, and generator

 

 

● Short strip production process and low production cost (see Fig. 1.1)

● The strip has excellent magnetic properties (Fig.1.2) and performance stability thanks to a special microstructure.

The composition and process parameters of the strip can be quickly adjusted to meet different application requirements.
