Alnico bar magnets have good thermal stability and are very suitable for high heat applications.
They have maximum working temperature which vary between 975 degrees to 1020 degrees.
Since they are hard and brittle, they cannot be subjected to conventional machining.
As compared to ceramics they have high residual induction and energy product.
If compared to ceramics and rare earth materials they have low coercive force.
