Axial Alnico Permanent Magnet

Cast Alnico Permanent Magnet With ±0.05mm Tolerance And BHmax 1.13-9 MGOe

Product Description:

Alnico Permanent Magnet is a kind of permanent magnet made of Alnico alloy. It is made by casting or sintering process. It is a magnetic material with high magnetic properties and dimensional stability. Alnico 8 is the most commonly used grade and LNG37H is the most common type of cast Alnico magnet. It has a high magnetic performance, with a maximum energy product of 1.13-9 MGOe and a maximum operating temperature of 550℃. Its tolerance is ±0.05mm, ensuring its high precision and reliability.

Packing and Shipping:

Alnico Permanet Magnet Packaging and Shipping

Alnico permanent magnets are usually packaged and shipped with the following two methods:

1. Standard Packaging

Standard packaging for Alnico Permanet Magnets includes plastic or paper bags. The package should be sealed and labeled to assure that the contents are not damaged by water or other elements during transport.

2. Special Packaging

For special applications, such as high temperature, high humidity, or corrosive environments, special packaging may be required. This may include plastic or metal containers, or special wrapping materials.
