Magnetic recording powder is mainly used for magnetic cards (eg: credit card, airline tickets) and magnetic disks. Compared with the regular magnetic ferrite powder, it needs higher intrinsic coercive force, better anti-oxidation properties as well as better temperature adaptability characteristic.
Unimagnet has been in the field of barium ferrite magnetic powder of magnetic recording for four years, and Hexagonal Barium Ferrite Powder is one of our main products. Stable particle shape, narrow particle distribution, high filling ratio, and good oxidation resistance guarantee that the magnetic powder can satisfy our customers with different requirements.
