Alnico Magnets

Custom Magnetic Filter, Magnetic Separator, Magnetic Coupling, and other Magnet
Assemblies are provided. As a magnetic products supplier, Leyuan Group has been
an experienced magnetic products manufacturer in China since 1995. We
manufacture a range of main magnetic products comprising magnetic filters,
magnetic couplings, permanent magnets, and customer design magnet assemblies.
These can be used in numerous fields including food processing, pharmaceutical,
and chemical development, etc.

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.
