AlNiCo magnets are a sophisticated alloy primarily composed of aluminum, nickel, cobalt, copper, and iron. It is available in two distinct forms: cast and sintered, each shaped by unique manufacturing processes. The cast AlNiCo magnets possess exceptional hardness and brittleness. Consequently, machining or drilling is not possible through conventional methods. The casting process usually entails the creation of holes at the foundry. The magnets are cast or sintered as closely as possible to the desired size, effectively minimizing the need for abrasive grinding to achieve the specified dimensions and tolerances.
