Alnico Permanent Magnet is a kind of permanent magnet made of Alnico material, which is widely used in a variety of applications, including Generators, Microphones, and Measuring Instruments. It is hard and brittle and has strong magnetic properties. Alnico magnets come in a variety of shapes, like Alnico8, Alnico rods, and Alnico magnets. The magnetic properties of Alnico magnets include high coercive force (Hcj) of up to 30 KA/m, and a high tolerance of ±0.05mm. Its magnetic properties make it an ideal choice for many applications. Alnico magnets are also highly durable and resistant to corrosion.
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 are packaged and shipped in secure and sealed containers to ensure they are not damaged during transit. Depending on the size, shape, and weight of the magnets, they can be packaged individually or in groups. For small, lightweight magnets, we use bubble wrap and cardboard boxes, and for larger magnets, we use wooden crates or pallets.
We use reliable and trusted carriers to ensure that our magnets are delivered to their destination safely and on time. Our carriers offer a variety of shipping options, including ground, air, and express, to meet the needs of our customers. We also offer international shipping for customers outside the United States.
