attributes of alnico:
very temperature stable, great for high heat applications
working temperature can reach 550-600 oc
does not lend itself to conventional machining (hard and brittle)
high residual induction and energy product compared to ceramic material
low coercive force compared to ceramic and rare earth materials (more subject to demagnetization)
