Cost-effective sintered/cast Alnico ring magnets used on speakers
Description
AlNiCo magnets are excellent temperature stability (max. working temperature up to 500⁰C), high residual induction, and can be made into very complicate shapes which are not possible for other magnets.
They do not require coatings because they are difficult to be eroded and oxidized.
Our company with China’s No.1 rare earth miner Chinalco has a strategic partnership, with a complete production chain and a sound quality assurance system.
Customized needs
To Order, please provide the following key requirements:
1. Performance requirements (such as Remanence Br, Intrinsic Coercivity Hcj, Working Temperture, etc.)
2. Shape and size (drawings are available)
3. Magnetizing direction (axial, radial, and other magnetizing angle)
4. Tolerance requirements (please pay attention to cost-effective, to avoid excessive quality)
5.Testing requirements
6. Futures requirements
7.Packing and transportation requirements
The performance and maximum processing accuracy of the AlNiCo rare earth magnet products provided by our company please refer to the following two tables:
