Wholesales AlNiCo Magnet for Sensors
China Wholesales AlNiCo Magnet for Sensors, Find details about China Cast AlNiCo Magnet, AlNiCo U Magnet from Wholesales AlNiCo Magnet for Sensors
Alnico permanent magnets were developed in the 1930's and were the first "Real" performance permanent magnets. They are made primarily from aluminum, nickel, cobalt, copper, iron and sometimes titanium. They can be either cast or sintered.
Products Overview
Alnico bar magnets offer excellent temperature stability, high residual induction, and relatively high energies.
Features include:
• Temperature stability in high thigh-temperature applications, and a maximum working temperature of approximately 1000°F
• Alnico bar magnets may be ground to size but not by conventional machining. We can grind them to your specifications.
• Alnico bar magnets have high residual induction and energy product compared to ceramic magnets, and low coercive force compared to ceramic and rare earth materials (more subject to demagnetization).
Common Characteristics of Alnico magnets
1. Very temperature stable, great for high heat applications
2. Wide range of working temperatures, up to 550ºC
3. May be ground to size
4. Does not lend itself to conventional machining (hard and brittle)
5. High residual induction and energy product compared to ceramic material
6. Low coercive force compared to ceramic and rare earth materials (more subject to demagnetization)
Size: Customized according to your requirement
