Alnico magnets is a Magnetic Materials product. Key specs — Origin: China (Mainland).
Product Description
Excellent temperature stability Good resistance to demagnetization from vibration and shock High residual density and magnetic stability Applications of Alnico Magnets Sensitive automotive Instruments Aircraft sensor applications Electronic distributors Magnetos Traveling wave tubes Electron tubes Radar Holding magnets Guitar pickups Telephones Generators and motors Alnico alloys basically consist of aluminum,nickel,cobalt,copper,iron and some grades cobalt and/or titanium are these alloys may contain additions of silicon,columbium,zirconium or other elements which enhance heat treatment response of one of the magnetic characteristics.   They are manufactured through either a casting or sintering process.
Cast magnets may be manufactured in complex shapes, such as horseshoes, not possible with other magnet materials.Sintered Alnicos offer slightly lower magnetic properties but better mechanical characteristics than cast Alnicos.
