Alnico Magnets
Alnico magnets are made primarily from aluminum, nickel, cobalt, copper, iron and sometimes titanium. There are cast or sintered Alnico magnet due to different process craft .
Applications of Alnico Magnets

> Relays | > Educational products |
Attributes of Alnico
> Very temperature stable, great for high heat applications
> Working temperature can reach 550-600 °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)
