Product Description
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.
Features:
- Product Name: Alnico Permanent Magnet
- Max Operating Temperature: 550℃
- Tolerance: ±0.05mm
- BHmax: 1.13-9 MGOe
- Magnetization Direction: Axial, Radial, Multi-poles...
- Application: Generator, Microphone, Measuring Instrument
- Specialty: Alnico9, Alnico Rod Magnet, Cast Alnico Magnet
Technical Parameters:
Characteristic of Both Cast and Sintered Alnico
Very temperature stable, great for high heat applications
Maximum working temperature 450-550°C
Does not lend itself to conventional machining (hard and brittle)
High residual induction and energy product compared to ceramic material
Low coercive force compared to ceramic and rare earth materials (more subject to demagnetization)
Most common grades of alnico are 5 and 8
Not suited for repelling or high friction applications

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.
