Physical Properties
Ferrite magnets feature moderate remanence (Br) for stable magnetic flux and high coercivity (Hci), giving strong resistance to demagnetization under load or heat. Their energy product ((BH)max) is lower than rare-earth magnets but sufficient for cost-effective motor and speaker applications. With a high Curie temperature (Tc) of about 450–460 °C, ferrite magnets maintain performance in elevated-temperature environments, making them durable, economical choices for various industrial uses.

FAQ
Why choose ferrite magnets for speakers instead of neodymium?
Ferrite magnets are cost-effective, highly resistant to corrosion and demagnetization, and perform well in most speaker applications, making them ideal for high-volume production.
Can you provide custom sizes or grades?
Yes, we offer OEM and customization based on your drawings or samples, including different outer/inner diameters, thicknesses, and magnetic strengths.
What testing methods ensure product quality?
We perform dimensional checks, magnetic flux measurements, pull-force tests, and salt spray testing to ensure consistency and durability.
