Features include:
• Temperature stability in high thigh-temperature applications, and a maximum working temperature of approximately 1000°F
• Alnico bar magnets may be ground to size but not by conventional machining. We can grind them to your specifications.
• Alnico bar magnets have high residual induction and energy product compared to ceramic magnets, and low coercive force compared to ceramic and rare earth materials (more subject to demagnetization).
• We stock Alnico bar magnets in Grade 5. We can supply grade 8 upon request. For a comparison of Alnico grades,

Dimensions are in inches. Direction of magnetization is through the length. Other sizes, shapes, and grades of Alnico are available from stock, and we can fabricate to your specifications.

Grinding and Tolerances
Alnico is hard and brittle, and is not suitable for drilling, tapping or conventional machining operations. Close tolerances are attained by abrasive grinding and cutting. Adams provides in-house cutting and grinding to meet your application requirements.

Temperature Constraints and Magnetization

Alnico has the best temperature coefficient of any but the most advanced commercial magnet material, providing for excellent stability over a wide temperature range. A properly designed circuit using alnico magnets will have a stable flux output during temperature fluctuations. Although Alnico displays considerable residual induction it conversely exhibits among the lowest coercivity of any magnetic material. A consequence of low coercivity is sensitivity to demagnetizing effects caused by external magnetic fields, shock, and application temperatures. For critical applications, AlNiCo Permanent Magnet can be magnetically stabilized to minimize these effects. Alnico magnets can be partially demagnetized if like poles of magnets are brought together. Placing individual magnets in contact with ferrous materials can also partially demagnetize them. Care must be taken in handling magnetized magnets. Typical open circuit Alnico 5 applications require a long magnetic length to pole surface ratio (usually 4:1 or greater) to ensure good magnetic performance. Check with Adams’ technical staff to confirm best ratio for your application.
