Competitive Price for Current Transformers Core - Low loss Sendust Core for AC inductors – Pourleroi Detail:
Sendust is a magnetic metal powder that was invented by Hakaru Masumoto at Tohoku Imperial University in Sendai, Japan, about 1936 as an alternative to permalloy in inductor applications for telephone networks. Sendust composition is typically 85% iron, 9% silicon and 6% aluminium. The powder is sintered into cores to manufacture inductors. Sendust cores have high magnetic permeability (up to 140 000), low loss, low coercivity (5 A/m) good temperature stability and saturation flux density up to 1 T.
Due to its chemical composition and crystallographic structure Sendust exhibits simultaneously zero magnetostriction and zero magnetocrystalline anisotropy constant K1.
Sendust is harder than permalloy, and is thus useful in abrasive wear applications such as magnetic recording heads.
Mainly used in power inductors, AC inductors, output inductors, line filters, power factor correction circuits and other switching power supplies, and sometimes replace air-gap ferrite as transformer cores;
Main features and advantages: When reducing the effective permeability of the magnetic core, during the application of the DC pulse, the small air gap evenly distributed in the magnetic core enables the winding to withstand a large DC component without saturating the magnetic core; Lower core losses than existing powdered iron core materials across the frequency range. It has a similar effect at any Gaussian value. Under the same test conditions, the temperature rise of the FeSiAl magnetic core is always less than half of the iron powder core, and the core loss is only 1/2 to 1/2 of the iron powder composition. 4. Under high frequency conditions, they are superior to iron powder cores and can meet the needs of high frequency power conversion equipment for inductors with extremely high efficiency; they can be used at frequencies above 8KHz; the saturation magnetic induction is around 1.05T; The shrinkage coefficient is close to zero, and no noise is generated when working at different frequencies; it has a higher DC bias voltage capability than MPP; it has the best cost performance.

Sendust core are formed by adding a certain amount of glass forming agent to the molten metal, and rapidly quenching and casting using a narrow ceramic nozzle under high temperature melting conditions. Amorphous alloys have the similar characteristics of glass structure, which not only make them have excellent mechanical properties, physical properties and chemical properties, but more importantly, the new technology of producing amorphous alloys using this rapid quenching method is less than the cold-rolled silicon steel sheet process. 6 to 8 processes can save energy consumption by 60% to 80%, which is an energy-saving, time-saving and efficient metallurgical method. Moreover, the amorphous alloy has low coercivity and high magnetic permeability, and its core loss is significantly lower than that of oriented cold-rolled silicon steel sheet, and its no-load loss can be reduced by about 75%. Therefore, the use of amorphous alloys instead of silicon steel sheets to manufacture transformer cores is one of the main means to save energy and reduce consumption in today’s power grid equipment.
