Cast Alnico 5 is the most commonly used of all the cast Alnico's .It combines high indications with a high energy product of 5 MGOe or more and is used extensively in rotation 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 butbutter 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 powder 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, alnico magnets
The Characteristics of Alnico Magnet:
