Overview of Ferrosilicon Spherical Soft Magnetic Alloy Powder

Ferrosilicon spherical soft magnetic alloy powder is an alloy of iron (Fe) and silicon (Si) that exhibits zachte magnetische eigenschappen. Soft magnetic materials are those that can be easily magnetized and demagnetized. Ferrosilicon, in particular, is favored for its hoge elektrische weerstand, which reduces wervelstroomverliezen in high-frequency applications. When processed into spherical powder form, this alloy becomes ideal for use in various poeder-Metallurgie en additieve productie applications due to its superior flowability and packing density.

Key Features of Ferrosilicon Spherical Soft Magnetic Alloy Powder:

  • Lage coërciviteit, meaning it can be easily magnetized and demagnetized.
  • Hoge elektrische weerstand, which minimizes energy losses in high-frequency applications.
  • Bolvorm, offering excellent flowability for powder-based processes.
  • Kosteneffectief, compared to other magnetic alloys like cobalt-based materials.
  • Corrosieweerstand, thanks to the silicon content.

Composition of Ferrosilicon Spherical Soft Magnetic Alloy Powder

Understanding the precise composition of ferrosilicon spherical soft magnetic alloy powder is crucial, as even slight variations can significantly impact its performance, especially in applications requiring high magnetic efficiency.
