Alnico 5 Permanent Magnets High Residual Induction For Guitar Pickup Makers

Alnico Permanent Magnets Alnico V Bar Magnet for Guitar Pickup makers
Alnico magnets, composed of primarily aluminum, nickel, and cobalt, were developed in the 1940's. The working temperature is up to 250 degrees c. Outer surface except pole can be red (smooth or wrinkle) painted. Coated Nickel, zinc, Chrome to maintain the magnetic strength. Deep pot magnets have a steel outer shell with a tapped hole in the back and a highly magnetic front face. The casting process allows for the magnet to be manufactured into intricate and complex shapes, which are not possible with other magnetic materials.This class of magnet remains a preferred material because of it's excellent temperature stability, high magnetic flux density, and resistance to corrosion. Alnico magnets are manufactured through a casting or sintering process.
 
Attributes of Alnico
• Very temperature stable, great for high heat applications
• 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)
• Working temperature can reach 550-600 °C
