Alnico5 Permanent Magnet For Measuring Instrument With Axial
Magnetization Direction
Product Description:
Alnico magnets are a type of permanent magnet composed of an alloy
consisting of aluminum, nickel, and cobalt. Alnico magnets are
characterized by their high common magnetic properties, high
temperature stability, and moderate coercive force. Cast Alnico
magnets are formed through a process of melting and pouring the
alloy into a mold to form the desired shape. Alnico magnets are
often used in generators, microphones, and measuring instruments.
The magnetization direction of Alnico magnets can be axial, radial,
or multi-poles, and they can be produced in a variety of grades.
Alnico 5 and 8 are the most commonly used grades. Furthermore,
Alnico magnets are known for their excellent tolerance of ±0.05mm.
Alnico magnets are highly valued for their strength, high
temperature resistance, and stability. In conclusion, Alnico
magnets offer a wide range of properties and can be used in a
variety of applications.

Packing and Shipping:
Alnico Permanent Magnets packaging and shipping:
Packaging: Alnico permanent magnets are usually wrapped in a thick
layer of plastic or cloth to prevent scratching and damage during
transportation. The package must be clearly labeled with the type
of magnet, size, and quantity.
Shipping: Alnico permanent magnets are usually sent by air freight
or ocean freight. If sent by air freight, the package must be
clearly labeled with the air freight carrier, the package size, and
the estimated delivery date.
