Alnico Permanent Magnet BHmax 1.13-9 MGOe Hcj ≥30 KA/M
Product Description:
Alnico Permanent Magnet is a type of permanent magnet made of cast
alnico, a combination of aluminum, nickel and cobalt. It has high
magnetic properties, with a maximum energy density (BHmax) ranging
from 1.13 to 9 MGOe. Alnico permanent magnet is widely used in many
applications, such as generators, microphones, measuring
instruments and many other industrial applications. Different
magnetization directions, such as axial, radial and multi-poles,
can be customized according to customers' special requirements.
Alnico magnets can be further divided into Alnico5, LNG37, and
other types. Alnico permanent magnets have high working temperature
and good corrosion resistance, making them an ideal choice for many
industries.
