The difference between different permanent magnetic material
Neodymium magnet, SmCo, ceramic magnet and AlNiCo can be used to make pot magnets
- Neodymium pot magnets have strong magnetic force and high performance.
- The advantage of ferrite pot magnets is economical price and moderate performance.
- AlNiCo pot magnets works well in extreme high temperature up to 550ºC. The maximum working temperature of samarium cobalt magnet is 350ºC.
