    Uses for our 12mm x 5mm Alnico Disc:
    There is no coating on our Alnico Disc range. Due to lacking a protective layer are more prone to chipping and weathering.

    Our Alnico Disc magnets also have a high-temperature tolerance Being able to resist demagnetization of temperatures of up to 540°C. A permanent loss in magnetism will result if exposed to temperatures above 540°C.

    Furthermore, these magnets are axially magnetized (through thickness) and are also referred to as a raw magnet due to not having any casing around the magnet itself.

    Customers use these magnets in a variety of applications such as in small sensors in electronics and general holding applications in the home, to massive separation systems in high-temperature environments.

    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 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 independent 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. A by-product 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.

    ALNICO magnets are made from aluminum, nickel, cobalt, copper and iron. Great for high heat applications. Maximum working temperature 975°-1020° F.
