product details

Manufacturing process

1). Dry process:By dry process combined with magnetic field orientation process, can produce isotropic & anisotropic magnets. The tool can be changed and developed easily.

2). Wet process:By wet process, only anisotropic magnets can be produced. It is complicated to change the tool and the tooling charge is much higher.

Magnetization:

1). Isotropic ferrite magnets are not oriented and can be magnetized in any direction.

2). Anisotropic ferrite magnets are different. They are oriented according to the manufacturing direction and must be magnetized strictly in the orientation direction.

Custom Magnetic Ring Ferrite Speaker Magnets, available in Y25, Y30, and Y35 grades, offer Good magnetic properties, excellent resistance to demagnetization, and long-term stability. With low cost and versatile shapes, these magnets are widely used in speakers, audio equipment, phones, TVs, and automotive applications, providing reliable and cost-effective solutions for various industries.
