SP2809 Ferrosilicon (gas-atomised) Powder FeSi

Ferrosilicium (gas-atomised) Powder Description

Ferrosilicium (gas-atomised) Powder comprises two of the Earth’s most abundant elements. It is a viable candidate for applications in the low- to mid-frequency range. The powder exhibits high saturation magnetisation, high permeability, electrical resistivity exceeding 50 µΩ-cm, low coercivity and limited hysteresis.

Ferrosilicium (gas-atomised) Powder Applications

As a soft magnetic material with low cost, Ferrosilicium (gas-atomised) powder finds a range of applications in power electronics and electrical machinery, as detailed below:

Electricity Conversion

High silicon steel fulfils the requirements for low- and mid-frequency applications (up to 1 kHz). It is used in high frequency chokes (up to 15 kHz) in the automotive, aerospace and stationary power generation sectors.

Electrical Machinery

Non-oriented silicon steel is utilised in electric vehicles. It is employed in drive motors, power steering motors, windshield wiper motors, seat adjustment motors, fuel pumps, HVAC compressors and fans, window lift motors and electric turbocharger motors. Steel with high silicon content is favoured due to its low raw material cost, near‑zero magnetostriction and reduced iron losses at higher frequencies.

Electronic Components

Soft magnetic materials in this category are used in dimmer switches, contact plates, heating valves, relay assemblies and cores for gas safety valves. For components requiring high electrical resistivity and high permeability, silicon steel is the conventional choice. For instance, pressure heads in impact printers used in ATMs employ this material.
