High Hcj Permanent Alnico Magnet Grade Alnico 5 BHmax 1.13-9 MGOe
Product Description:
Alnico permanent magnets are magnets made from cast Alnico that
exhibit permanent magnetism. These magnets are used in a variety of
applications, such as generators, microphones, and measuring
instruments. Alnico permanent magnets are known for their superior
magnetic properties, including a high BHmax of 1.13-9 MGOe and
tight tolerance of ±0.05mm. Moreover, the magnetization direction
of Alnico permanent magnets can be axial, radial, and multi-poles.
Permanent Alnico magnets, with their high quality and reliable
performance, are an ideal choice for many applications.
