Sintered Alnico Magnet is a Magnetic Materials product. Key specs — Origin: China; Price Term: FOB.
Product Description
Alnico magnet is a kind of alloy consisting primarily of iron,aluminum, nickel,cobalt,with minor amounts of other elements including copper and titanium.
Alnico magnet alloy is a mature technology and is manufactured by casting or Alnico magnet is produced by conventional foundry methods using resin bonded sand molds,it is suitable for complex geometries and configurations not achievable with other magnet Alnico can be tailored easily to obtain a variety of magnetic properties and characteristics.
Specialized casting techniques are used to achieve the unique crystalline grain orientation found in Alnico 5-7(LNG60). Sintered Alnico magnet is produce by powder metallurgy. Shaped by dry powder press,sintered in vaccum sintering furnance.
Both Cast Alnico and sintered Alnico's property are optimized during a heat treatment process which is unique to Alnico.Physical characteristics of AlnicoAlnico material are hard and brittle and are not suited to drilling,tapping,or machining operations.Tolerances closer are achieved only by abrasive grinding and cutting.Due to its brittle nature,Alnico should not be used as a structural component in any device.
Strengths: High temperature ability,high corrosion resistance,good magnetic stability Weaknesses: Poor resistance to demagnetisation,high cost,brittle
