Strong Power Alnico 8 Bar Magnet
Alnico Magnet
Produced by casting or sintering powder metallurgical technique with alloy composite of Al-Ni-Fe-Co
Alnico is a very hard and brittle material and does not lend itself to conventional machining.
UNMAG have experienced machinists and the proper equipment to grind alnico to its required dimensions.
Characteristic of Both Cast and Sintered Alnico magnet
Very temperature stable, great for high heat applications
Maximum working temperature 450-550°C
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)
Most common grades of alnico are 5 and 8
Not suited for repelling or high friction applications
