Introduction of iron silicon aluminum magnetic powder core

Iron silicon aluminum magnetic alloy was invented by the Japanese in the 1930s. It was invented in Sendai County, so it is also called sendust alloy. Subsequently, it was made into magnetic particle core in the early 1980s, also known as sendust magnetic particle core. Welcome to the company website http://www.mwaya.com

Iron silicon aluminum magnetic alloy was invented by the Japanese in the 1930s. It was invented in Sendai County, so it is also called sendust alloy. Subsequently, it was made into magnetic particle core in the early 1980s, also known as sendust magnetic particle core, which is represented by CS. The magnetic properties of Fe Si Al powder magnetic core are similar to those of high flux magnetic core, and the loss is lower than that of high flux magnetic core, but its price is much cheaper. Therefore, it has been used more and more widely in recent years. Iron silicon aluminum magnetic particle core can be used wherever it can replace MPP and high flux magnetic particle core.

The standard composition of Fe Si Al alloy is: al5.4%; Si9.6%； The rest is iron. The control range of alloy composition for producing iron silicon aluminum magnetic particle core is al5.2-5.6%; Si9.2-9.8%； The rest is iron. The iron silicon aluminum iron powder core used at low frequency (below 1kHz) has the highest effective permeability μе 147。 At present, the iron silicon aluminum magnetic particle cores we mass produce and supply have the following performance grades: μе 26； μе 60； μе 75； μе 90； μе 125, etc., which is also the most commonly used. The saturated magnetic induction BS value of iron silicon aluminum magnetic particle core is 800-1000mt. The number of ampere turns used is about 300. The product pressing density is 5.2-6.0. Various common specifications of iron silicon aluminum magnetic particle core are shown in Table 3. The coating color code of iron silicon aluminum magnetic particle core produced by us is black. It can also be coated according to the color code required by the user. The marking method of iron silicon aluminum magnetic particle cores of various specifications and models is expressed by CS plus outer diameter and effective permeability. For example, the model cs330125 represents 33 × twenty × 10.7㎜ μе Iron silicon aluminum magnetic particle core (see high flux magnetic particle core for details).
