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.
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 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.
