Product Advantages & Features

The engineering behind the ferrous powder yields several distinct physical and magnetic benefits:

Smooth Particle Surface

The highly spherical morphology ensures exceptional flowability during molding and pressing, significantly reducing die wear and improving automated handling.

Excellent Dispersion

The powder exhibits flawless single-particle dispersion. The complete absence of agglomeration and satellite particles ensures uniform density throughout the pressed core.

Guaranteed High Purity

Manufactured with a base purity of >99.5%, the powder minimizes unwanted inclusions that could disrupt magnetic domains and degrade performance.

Controllable Oxygen Content

Oxygen levels are strictly managed, ranging from <3000 ppm to <8000 ppm across different grades, allowing manufacturers to balance core compressibility with internal insulation requirements.

Wide Adjustable Size Range

The material is available in a highly customizable particle size range (including CFN and PFN specifications), enabling precise matching for specific permeability and frequency targets.

Superior Magnetic Performance

The combination of spherical shape and phase purity directly contributes to higher packing density, translating to lower core loss, reduced eddy currents, and improved DC bias characteristics in finished inductors.
