Cylinders Shape Cast Alnico 8 Magnet Customized Of Ground Surface
Cast Alnico magnet is composed primarily of Aluminum, Nickel, Cobalt, Copper and Iron. It has very good corrosion resistance and high temperature operation.
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)
