Alnico Magnets

Types Of Alnico Pickup Permanent Magnets For Sale

A high working temperature limit (550°C/1020°F) makes Alnico especially well-suited for sensitive automotive and aircraft sensor applications. Alnico is produced in many grades to fit the requirements of these applications, from Alnico 1 to Alnico 12, but the most popular grades are 2, 5 and 8. By comparison to the newer materials, the coercivity of Alnico is low.

Where Alnico is appropriate, magnet size can be minimized if it can be magnetized after assembly into the magnetic circuit. If used independently of other circuit components, as in security applications, the effective length-to-diameter ratio (related to the permeance coefficient) must be great enough to cause the magnet to work above the knee in its second quadrant demagnetization curve. For critical applications, Alnico magnets may be calibrated to an established reference flux density value. However, a result of low coercivity is sensitivity to demagnetizing effects due to external magnetic fields, shock, and application temperatures. For critical applications, Alnico magnets can be temperature-stabilized to minimize these effects.
