Alnico Bar Magnet 180 mm Length Painted Red and Blue Color for Education science
Magnetic Alnico Bar are made primarily from aluminum, nickel, cobalt, copper, iron and sometimes titanium. They can be either cast or sintered and be applied widely in our daily life. Especiall for Educational Purpose.
Their Advantage: 1. They have stable temperature coefficient and great for heat applications. The working temperature can reach 550-600 °C.
2. High residual induction and energy product compared to ceramic material
3. Low coercive force compared to ceramic and rare earth materials (more subject to demagnetization)
Shortage: Cast Alnico Magnet are hard and brittle, not easily to conventional machining.
The common grade is AlNiCo 5 and AlNiCo 8.
