Alnico alloys have some of the highest Curie temperatures of any magnetic material, around 800 ° C (1, 470 ° F), although the maximum working temperature is normally limited to around 538 ° C (1, 000 ° F). They are the only magnets that have useful magnetism even when heated red-hot. This property, as well as its brittleness and high melting point, is the result of the strong tendency toward order due to intermetallic bonding between aluminium and its other constituents. They are also one of the most stable magnets if they are handled properly. Alnico magnets are electrically conductive, unlike ceramic magnets.
Cast Alnico Magnet Feature:
1. 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.
2. Eclipse Magnetics Alnico magnets are ideal for high temperature applications up to 550° C
3. 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
4. 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.
Alnico Magnet Application:
1. ABS braking system magnets
2. ABS braking system magnets
3. Reed switch operating magnets
4. Electricity meter damping magnets
5. Holding/clamping applications
6. Microwave applications
7. Weighing scale damping magnets
