Buy alnico magnets on-line today! We carry a large inventory of alnico grade 8 disc & alnico grade 5 rod magnets, available in a wide range of sizes and shapes, not all of which is shown on this website. Alnico magnets, are part of the permanent magnet family, and they are relatively high in magnetic strength. These powerful magnets offer excellent temperature stability & can be used at temperatures up to 1000⁰F (500⁰C). Because of their relatively high strength and temperature stability, alnico magnets are commonly used for industrial applications such as rotating machinery, meters, instruments, sensing devices holding applications and more. Alnico magnets are manufactured through either a casting or sintering process, so they can be made into complex shapes such as horseshoes, which is not possible to do with some of the other magnet materials. We can also custom manufacture these to your exact specifications using our in-house global manufacturing facilities and our experienced team of engineers. Just let us know what you are looking for by sending us a request for quote or contact us today, and we'll work with you to determine the most economical way of providing you with what you need. Features & Characteristics of Alnico Magnets What are the main characteristics of alnico magnets? Alnico magnets offer high magnetic strength, energies but low coercivities. They are less brittle than Rare Earth magnets, are highly resistant to corrosion, have excellent temperature stability and can be used at very high temperatures. Manufactured through either a casting or sintering process, they can be made into complex shapes (such as horseshoe shapes) that are not possible with other magnet materials. (top) What grades & shapes are available for alnico magnets? Grades 5 and 8 are the most commonly used Alnico grades. Non-standard shapes can be custom fabricated to blueprint specifications from raw stock in sintered, or cast forms, & we can custom manufacture virtually any shape & size to meet your specialty requirements. Send us a request for quote, and we'll work with you to determine the most economical way to manufacture your specialty project. (top) Are there machining constraints for alnico magnets? Alnico magnets are hard and brittle, and prone to chipping & cracking. They require very careful machining & it is not generally recommended that these materials be used for structural or decorative purposes. Machining or drilling cannot be accomplished by ordinary methods. Cutting & grinding should be done prior to magnetizing. Holes must be made by EDM methods. We are fully equipped to machine these materials to your blueprint specification
