New Mini Alnico Magnets With Good Performance
General Description:
Alnico describes a family of materials,which is derved from a common base composition comprising of aluminum,nickel,cobalt and iron with varying additions of other elements.By varying the composition it is possible to tailor the magnetic properties to meet the needs of a wide variety of end use applications.There are two different manufacturing processes for Alnico:Cast Alnico can be made into many size and shapes,whereas Sintered Alnico si usually restricted to smaller sizes.However,both processes are not suitable for complex geometry and configurations,both alloy systems are hard and brittle and do not lend themselves to conventional machining.Standard Sintered Alnico has tighter dimensional tolerances due to its processing.It also has slightly lower magnetic properties,but better mechanical strength than Cast Alnico products.Alnico alloys .which possess the lowest reversible temperture coefficient magnetism in permanet magnet materials,have excellent working temperature up to 600℃ High Nickel content of Alnico alloy results in good stability against corrosion and oxidation,this metalic compositions is also a good electrical conductor.
Characteristics:
1.Suitable for small volume magnet with complex shape.
2.Compact crystal ,high intensity.
3.Regular shape,precision size.
4.Even elements,stable performance.
5.Suitable for compound magnet.
6.Excellent temperature stability(temp.coefficient of Br is the smallest among all of the other permanent magnets).
