Axial Magnetization Alnico9 Magnets With Tolerance ±0.05mm
Product Description:
Alnico Permanent Magnet is a high performance permanent magnet
material which is composed of iron, aluminum, nickel, cobalt and
other alloy elements. It is a ferromagnetic material with high
magnetic properties, superior corrosion resistance and excellent
temperature stability. Alnico magnets are available in different
grades such as Alnico9, Alnico5, Alnico8. It can be made into rod,
ring, and disc shape, etc.
Alnico9 is the highest performance and most widely used type of
Alnico magnet. It is a cast Alnico magnet with high residual
induction (Hcj) of ≥30 KA/m. Its maximum operating temperature is
550℃ and the tolerance is ±0.05mm. The maximum energy product
(BHmax) range is 1.13-9 MGOe.
Alnico9 magnet is suitable for use in applications requiring high
temperature, good corrosion resistance, excellent machinability,
and high magnetic field output. It is widely used in various fields
such as motors, generators, transducers, sensors, and
instrumentation. It is also commonly used in aerospace, automotive,
and medical industries.
