AlNiCo Magnets

Using patterns and simple moulding techniques, Cast AlNICo Magnet can be cast to form a vast range of complex shapes and sizes at an economical cost.

. Alnico magnets are ideal for high temperature applications up to 550ºC
. Cast AlNICo Magnet is very stable, has good corrosion resistance and a typical hardness of 50 Rockwell C.   Once cast, the material is so hard that the only machining possible is grinding
. Cast AlNICo Magnet represents the most versatile magnet material available. The range of properties can be accurately designed for specific applications by changes to element analysis and heat treatment.

Specifications
Alnico magnet
s are made from aluminum, nickel, cobalt, iron and a few other elements such as copper, titanium and sulfur etc. Because of their high magnetic flux density and superior temperature stability,

Alnico magnets are widely used in instruments, meters, speakers, electricity motor, sensor, microwave device, automatic control appliance, aviation, spaceflight and military technology, etc.

AlNiCo advantage
1.Compact crystal, high intensity, good chemistry Stability, strong anti-corrosion.
2.Even elements, excellent and stable magnetic performance;
3.Excellent temperature stability (temp. coefficient of Br is the smallest among all of the other permanent magnets.)

4.Highest usage temperature reach 500ºC 5.Suitable for small volume and complex shape and magnet assemble for sintered Alnico.
