Cast Alnico Magnets

Customized Cast Alnico MagnetsAlnico material is comprised of aluminum,Website:, nickel, cobalt and iron with varying additions of other elements. There are two different manufacturing processes for Alnico: Cast and sintered.Cast Alnico magnets can be made into many shapes and sizes during manufacturing process by using the casting processing method. Cast Alnico magnets are manufactured by pouring the molten metal alloy of Alnico into a mold and then further processing it through heat treated and cooled alternatively. The solidified material has a dark gray appearance on the exterior and may be roughly ground. Magnets that have been polished using machines, may have a shiny gray surface similar to that of steel.Dimension                     ToleranceUp to 1" Up to 25.4 mm          ±1/64" .40 mm1" to 3" 25.4 to 76.2 mm        ±1/32" .81 mm3" to 5" 76.2 to 127.0 mm       ±3/64" 1.19 mm5" to 7" 127.0 to 177.8 mm      ±1/16" 1.59 mm7" to 9" 177.8 to 228.6 mm      ±5/64" 1.98 mmAdvantages of Alnico Magnets1.Cast Alnico offers a near net shape. 2.Cast alnico can be produced to complex shapes with complex magnetic patterns.  3.Alnico Br as high as NdFeB at room temperature.4.Can be used up to 450-550 degrees C (842-932F). 5.Least variation in magnetic output with temperature change of any magnetic material. 6.Can be cast in very large sizes.Production Properties:Our regular sizes for reference:Applications:Mainly used for a variety of Meter, Odometer, Sensors, Motors, Multimeter, Tele, Mobile, Watermeter, Eletricitymeter, Switch, Adhesion, Loudspeakers Port machines, Musical instruments, Magnetic chucks, Educations, Magnetic Bases etc.
