1, ferrite low performance and medium, the lowest price, good temperature characteristics, corrosion resistance, performance and price ratio.
2, NdFeB has the highest performance, price, good strength, high temperature resistance and corrosion resistance
3, samarium cobalt high performance, the highest price, brittle, excellent temperature characteristics, corrosion resistance,
4, AlNiCo low performance and medium, the price, excellent temperature characteristics, corrosion resistance, poor interference resistance
5, SmCo, ferrite, NdFeB can be made by sintering and bonding methods, high sintering magnetic properties, poor molding, good shapeability of bonded magnets, and much lower performance.
6, AlNiCo can be produced by casting and sintering methods, casting magnets have higher performance, poor formability, lower sintered magnets, and better formability.
