Matériau Magnétique Doux.png


Soft magnetic materials are those that can be easily magnetized and demagnetized. They are widely used in electronics and electrical engineering. Here are several types:

  1. MnZn Ferrite Powder:

  • Typically used in applications requiring low losses at high frequencies.

  • Ideal for transformer cores and inductor cores at frequencies below 5 MHz.

  • Has high permeability and moderate saturation flux density.

 2. FeNi Powder for Powder Core:

  • FeNi powder, often called permalloy when it contains a high nickel content, is used for its high magnetic permeability and low coercive force.

  • It is suitable for high frequency power converters, inductors and transformers.

 3. FeSiAl Powder for Powder Core:

  • Also known as Sendust, it is suitable for applications requiring low core losses and relatively high saturation flux density.

  • Often used in power electronics, such as switching power supplies and noise suppression.

 4. FeSi Powder for Powder Core:

  • This material is commonly used in applications where cost is a critical factor, as it is generally less expensive than other options.

  • It has moderate magnetic properties and is used in various filter applications and in inductors.

Each powder type is optimized for different magnetic and electrical properties, such as permeability, saturation flux density, resistivity and operating frequency range. The choice among them depends on the specific application requirements, including environmental conditions and cost considerations.
