Key Advantages
- Excellent Temperature Stability
It offers outstanding temperature stability with very low demagnetization rates at elevated temperatures, outperforming ferrite and NdFeB magnets. They can operate reliably in a wide temperature range from -60°C to 540°C with minimal magnetic performance loss.
- Natural Corrosion Resistance
With inherent resistance to corrosion, AlNiCo magnets do not require surface coating and can be used directly in humid or mildly corrosive environments, ensuring long-term stability and reduced maintenance costs.
- High Residual Flux & Flexible Forming
Featuring high residual induction, AlNiCo magnet provide strong magnetic output. They can be produced through casting or sintering into various shapes, supporting diverse design requirements for industrial and precision applications.

FAQ
Do AlNiCo magnet require surface coating?
No. AlNiCo magnets have natural corrosion resistance and can be used without any surface coating, even in humid environments.
Are AlNiCo magnets easy to demagnetize?
AlNiCo magnets have high residual flux density but relatively low coercivity, which means proper magnetic circuit design is important to prevent demagnetization during use.
Can AlNiCo magnet blocks be customized?
Yes. We support customization in size, shape, magnetic grade, tolerance, and magnetization direction based on customer drawings or application requirements.
