Magnetic Powder

Magnetic powder refers to a type of functional powder material with magnetic properties, mainly composed of magnetic metal or alloy particles (such as iron, cobalt, nickel) or ferrite compounds. Its particle size typically ranges from a few micrometers to hundreds of micrometers, and it can be processed into different shapes (spherical, irregular) and magnetic grades based on application needs.

Depending on the magnetic retention ability, it is generally divided into two categories:

Soft magnetic powder: Easily magnetized and demagnetized, with low coercivity, suitable for scenarios requiring dynamic magnetic field changes.

Hard magnetic powder: Hard to demagnetize after magnetization, with high coercivity, ideal for manufacturing permanent magnetic components.

logoAdvantages

Excellent magnetic performance: It can efficiently respond to magnetic fields, realizing functions such as magnetic adsorption, magnetic separation and magnetic induction, and its magnetic strength can be customized according to formulas.

Good processability: It can be mixed with polymers, resins or metals to form composite materials (e.g., magnetic plastics, magnetic coatings), and is easy to shape into complex structures through molding, coating and other processes.

Wide adaptability: It has stable chemical properties, can resist corrosion (especially surface-treated magnetic powder) and high/low temperatures in most environments, and is not easily degraded by external factors.

Cost-effectiveness: Compared with integral magnetic blocks, it has lower raw material waste and production costs, especially suitable for large-scale and small-batch customized production.
