Block Sinter Alnico LNG40 Permanent Magnets Guitar Pickup High Temperature Resistance
Description :
The casting process allows for the magnet to be manufactured into intricate and complex shapes, which are not possible with other magnetic materials.
Attributes of Cast 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)
Applications of Cast Alnico
Electricity Meters
Water Meters
Motorcycle odometers
