Alnico Permanent Magnet is a type of permanent magnet that is widely used in various industrial and commercial applications. It is available in several grades, including Alnico 5, Alnico 8, Alnico 8M, Alnico 9, Alnico 5, and Neodymium. It is highly magnetized with a high BHmax of 1.13-9 MGOe and can be magnetized in axial, radial, and multi-pole directions. The tolerance is ±0.05mm. Alnico 8 and LNG37 are the most common grades that are normally used.
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

Alnico Permanent Magnet Packaging and Shipping
Alnico Permanent Magnets are packaged and shipped in sturdy cardboard boxes. The boxes are lined with a protective material such as bubble wrap to protect the magnets during transit. The boxes are then sealed with strong adhesive tape and labeled with an identification number. The magnets are then loaded onto a pallet and securely strapped for shipment.
