Meet the "Iron **" material

Iron end

The full name of iron soft magnetic powder is specifically referred to as those magnetic materials with small coercive force, easy magnetization and demagnetization. The so-called soft refers to the fact that these materials are easily magnetized and exhibit "soft" magnetic properties. The use of soft magnetic materials is very extensive. Because they are easy to magnetize and demagnetize, and have a high magnetic permeability, they can play a good role in gathering magnetic lines of force. Therefore, soft magnetic materials are widely used as paths for magnetic lines of force, ie, as magnetically conductive materials, such as transformers and sensors. The core, magnetic shield, special magnetic circuit yoke and so on.

Iron core

The full name of the iron magnetic core magnetic alloy was invented by the Japanese in the 1930s. It was invented in Sendai, it is also called Sendust alloy. Then, in the early 1980s, it was made into a magnetic powder core, also called Sendust magnetic powder core, and we used CS to represent it. The magnetic properties of the iron core are similar to those of the high-throughput magnetic powder core, and the loss is lower than that of the high-throughput magnetic powder core. However, its price is much lower. Therefore, it has become more and more widely used in recent years. Wherever it is possible to replace MPP and high-flux magnetic powder cores, FeSiAl magnetic powder cores can be used as much as possible.

The standard composition of iron silicon aluminum alloy is: AL 5.4%; Si 9.6%; The rest is iron. The control range of the alloy composition for the production of iron silicoaluminum magnetic powder cores is: AL 5.2-5.6%; Si 9.2-9.8%; the balance is iron. Iron cores used at low frequencies (below 1 kHz) have an effective magnetic permeability up to μе147. At present, we have a large number of production of iron powder magnetic core has the following performance levels: μе26; μе60; μе75; μе90; μе125, etc., which is also the most commonly used. The saturation magnetic induction Bs value of the iron core is 800-1000mT. The number of ampoules used is about 300. Product compression density 5.2-6.0. See Table 3 for various common specifications of iron** magnetic powder cores. The coating color code of the iron core powder we produce is black mark. It can also be coated according to the user's requirements. The marking method of iron cores of various specifications and models is indicated by CS plus outer diameter and effective permeability. For example, model CS330125 shows a 33×20×10.7mmμf iron core (see High-throughput magnetic powder core for details).

Iron ** magnetic ring

Generally used for switching power supply, he has a low temperature rise, high saturation flux density, high magnetic permeability C, the main series products are iron powder core magnetic ring 28, iron powder core magnetic ring 26 (yellow white ring ), Iron powder core magnetic ring 52 material (blue green ring), iron powder core magnetic ring 33 material (gray yellow), iron powder magnetic core ring 18 material, iron powder core magnetic ring 2 material (red gray ring), iron powder 40 magnetic core material (green yellow ring), magnetic iron core material 8 (yellow red ring) and so on. Iron ** magnetic ring
