AlNiCo magnet has the advantages of high remanence (up to 1.35T), low coercivity (usually less than 160kA/m) and nonlinear demagnetization curve, so AlNiCo magnet is easy to be magnetized, but also easy to demagnetize. Special attention should be paid to its particularity in the design and manufacture of magnetic circuit of devices, and the magnet must be stabilized in advance. AlNiCo permanent magnet material has low mechanical strength, high hardness, crisp quality and poor machinability, so it can not be designed as structural parts. It can only carry out a small amount of grinding or electric discharge machining during processing, and can not use forging and other mechanical processing.

AlNiCo horseshoe magnet is a classic Alnico magnet shape. Sometimes AlNiCo horseshoe magnet is called a C-shape magnet.It is strictly prohibited to contact with any ferromagnetic material during use, so as not to cause local irreversible demagnetization or distortion of flux density distribution.

Among permanent magnet materials, casting AlNiCo permanent magnet has the lowest reversible temperature coefficient. AlNiCo horseshoe magnet has good temperature stability and aging stability. AlNiCo horseshoe magnets are capable of operating at temperatures of up to a maximum of +550 degrees C. AlNiCo horseshoe magnets are supplied in natural (uncoated / unpainted) and red paint finishes. AlNiCo horseshoe magnets can be offered in other dimensions and grades, and is suitable for making instruments, motors, electroacoustic devices, magnetic machinery, etc.
