Product Description

The AlNiCo materials (composed predominantly of Aluminum, Nickel, and Cobalt with minor amounts of other elements including Titanium and Copper) permit design latitudes providing high indications, high energies and relatively high coercivities. AlNiCo magnetic material are manufactured through either a casting or sintering process. Specialized casting techniques are used to achieve the unique crystalline grain orientation found in the Alnico 5 and 8 grades. These anisotropic grades are designed to produce high magnetic output in a specified direction. Alnico 5 and Alnico 8 are anisotropic and exhibit a preferred direction of orientation. Magnetic orientation should be specified on your drawing when you send an order to us. Cast Alnico 5 is the most commonly used of all the cast Alnicos. It combines high inductions with a high energy product of 5MGOe or more and is used extensively in rotating machinery, communications, meters and instruments, sensing devices and holding applications. The higher resistance to demagnetization (coercive force) of Alnico 8, cobalt content to 35%, allows this material to function well for short lengths or for length to diameter ratios of less than 2 to 1. Sintered Alnico materials offer slightly lower magnetic properties but better mechanical characteristics than the cast Alnico materials. Sintered Alnico magnets are most suitable in small sizes (less than 1 oz.). In this process, the desired mix of metal powders is pressed to shape and size in a die, then sintered at 2300?F in a hydrogen atmosphere. The sintering process is well suited to large volume production, and results in parts which are structurally stronger than cast magnets. Relatively close tolerances can be achieved without grinding

AlNiCo-magnet can be used for continuous duty applications where temperature extremes up to 550℃. AlNiCo is very hard and brittle. Machining or drilling can not therefore be accomplished by ordinary methods. Holes are usually cored in at the foundry. Magnets are cast or sintered as closely as possible to required sizes so that abrasive grinding to finished dimensions and tolerances is minimized
