Corrosion Resistance
Alnico magnets exhibit a high degree of corrosion resistance and are typically employed in applications with no coatings or plating.
Temperature Effects
Alnico magnets offer the best temperature characteristics of any standard production magnet material available. Alnico magnets can be used for continuous duty applications where temperature extremes up to 930°F (500°C) can be expected.

Magnetization Options
The lower coercive force of Alnico makes magnetizing a simple matter in most cases. In order to optimize the performance of Alnico magnets, it is advisable to magnetize the magnet after assembly with other circuit components.
Compliance and Intellectual Property Considerations
Alnico magnets manufactured by Dura Magnetics are compliant with Intellectual Property Rights, Environmental Restrictions, and Conflict Mineral usage.

Alnico Magnet Manufacturing Methods
Alnico magnets are typically manufactured by a powdered metallurgical process utilizing rigid steel or rubber molds.
DFARS & ITAR Compliance
Limited availability of Defense Federal Acquisition Regulation Supplement (DFARS) compliant material can make small magnet production runs costly. However, we stock various grades at our U.S. facility, enabling us to provide cost-effective, DFARS-compliant magnets for all customers if needed, regardless of project size or requirements.
We are also registered and compliant with the International Traffic in Arms Regulations (ITAR). This qualifies us to work with items listed on the United States Munitions List (USML). We are also ITAR registered with the Directorate of Defense Trade Controls (DDTC).
