Material Description

Fe-based nanocrystalline alloys are composed of iron, silicon, boron, niobium and copper.Iron base amorphous alloy containing Cu and Nb will form very fine grain structure when annealed above the crystallization temperature, and the grain size is only 10-20 nanometers. The crystalline material formed by special crystallization annealing of this amorphous alloy is called nanocrystalline alloy.Nanocrystalline material with high saturation magnetic induction intensity, high permeability, low coercive force, low loss and good stability, high strength, toughness and wear resistance corrosion resistance and other excellent properties, as in the metal soft magnetic material which has the best performance/cost ratio of nanocrystalline alloy material, can replace silicon steel, permalloy and ferrite become the high-frequency transformer, transformer, inductance components ideal material.

Application field

* EMC common mode, differential mode filter inductance core;

* Switch power supply large and small power transformer core;

* Core of current transformer with different precision (zero sequence, leakage protection);

* Magnetic amplifier, peak suppressor, saturation inductance core.

Amorphous is a new kind of soft magnetic alloy material, it adopts the international advanced super quenching technology will molten metal at millions of degrees per second direct cooling, formation thickness of 25 to 28 m amorphous thin belt, get on the atomic arrangement of short-range order, long-range disorder characteristics of amorphous gold group, on the microstructure of completely different from the traditional metal and alloy material. Therefore, in the physical properties, chemical properties, mechanical properties and many other aspects of traditional metal materials with incomparable excellent characteristics. And, in terms of its preparation technology is completely different from the traditional metallurgical technology, made of amorphous thin liquid steel step belt, eliminating the traditional metallurgical technology of casting, forging, intermediate annealing, rolling process, saves a large amount of energy, and no pollutants, amorphous alloy is regarded as a new type of green environmental protection, energy saving and efficient materials.

Iron based amorphous strip, with its high permeability, high saturation magnetic sensitivity, low iron loss and excellent stability, meets the needs of electronic products to high frequency, high current, miniaturization and energy saving, can replace silicon steel, permo alloy and ferrite, widely used in power and electronic products.
