Contact UsThese aluminum, nickel and copper magnets are sintered in Inconel boats to form small magnets no greater than 2 inches in any direction.
Material Composition
Aluminum, Nickel, Cobalt, and Iron powder that is pressed and sintered into its final form.
Key Properties
Stronger magnetic performance than cast Alnico, excellent resistance to demagnetization, and good stability in high temperatures.
Temperature Range
Can withstand temperatures up to 480°C, making it ideal for high-temperature applications.
Manufacturing Notes
The sintering process gives a more uniform microstructure compared to casting, leading to improved magnetic performance. However, it is harder and more brittle, requiring careful handling during machining.
Common Uses
Pressure gauges, magnetrons, amplifiers, sensors, and meters.
