AlNiCo Magnets & Custom Assemblies

Features & Characteristics

  • AlNiCo permanent magnets are made up of alloys that include iron, aluminum, nickel, and cobalt. Other elements (e.g., copper and titanium) may be included in minor amounts.

  • AlNiCo magnets are graded based on their cobalt content. This ranges from 0% (AlNiCo 3) to 40% (AlNiCo 8).

  • Lower grades (Mulberry’s AlNiCo 2, 3, and 4) are un-oriented or isotropic. In other words, their magnetic properties are the same in all directions rather than optimized along a particular axis. Magnetic output is relatively low.

    Anisotropic grades (Mulberry’s AlNiCo 5, 6, 8, and 9) are designed to produce high magnetic output in a specified direction. We achieve orientation of magnetic output during heat treatment by controlled cooling of the product from about 2000°F within a magnetic field.

  • AlNiCo magnets are heat-resistant, produce a strong magnetic field, and are durable. Their ability to conduct electricity makes them useful in a variety of applications.

Applications

  • Electric Motors

    AlNiCo magnets are stable at high temperatures and reliable over time, making them a common choice for use in electric motors.

  • Precision Instruments

    Precision measuring instruments such as speedometers and tachometers utilize AlNiCo magnets because of their accuracy and consistency in changing conditions.

  • Aerospace Components

    Aircraft gyroscopes and navigation equipment use AlNiCo magnets because of their resilience in temperature extremes and their ability to withstand vibrations.

  • Military Radar Equipment

    Radar systems rely on AlNiCo magnets because they can withstand temperature extremes reliably.
