Sintered Alnico Magnets-tend To Be Small, Thin, Light And Complex Magnets Manufactured through powder metallurgy technology, sintered AlNiCo magnets resemble other sintered magnets. They come in small, thin, and complex shapes with high dimensional accuracy and strict tolerances. Sintered AlNiCo magnets also possess superior mechanical strength and machinability. They utilize materials better and have lower composition segregation and magnetic property fluctuation compared to cast AlNiCo magnets. Though their overall magnetic properties are slightly lower than cast AlNiCo magnets, sintered AlNiCo magnets are still a reliable option for certain applications. Cast AlNiCo magnets are more commonly used due to their higher magnetic properties.
Cast Alnico Magnets-more Widely Used Alnico Magnets The production of Cast AlNiCo magnets involves a traditional casting process wherein the aluminum nickel cobalt alloy with varying components is melted and poured into resin sand molds. Subsequently, it undergoes a heating and cooling process to solidify the material with a rough surface. Cast AlNiCo magnets can be divided into anisotropic and isotropic types depending upon the application of a magnetic field orientation during cooling. In cast AlNiCo magnets, anisotropy is characterized by a shape anisotropy resulting from slender Fe-Co particles arranged parallel to the magnetic field during amplitude modulation decomposition. Hence, after heat treatment, the AlNiCo material is crafted into specific geometry and tolerance.

Application of AlNiCo Permanent Magnets
AlNiCo permanent magnets find widespread application in industries such as automotive, aerospace, power generation, and telecommunications. They are used in relays, sensors, meters, loudspeakers, motors, magnetic chucks, and holding systems due to their high magnetization stability, good temperature stability, and excellent corrosion resistance. AlNiCo magnets are also utilized in medical equipment, musical instruments, and educational kits, making them a versatile and reliable option for various applications.
Details of AlNiCo Magnets
As a non rare earth metal permanent magnet material, the composition of Aluminum Nickel Cobalt(AlNiCo) alloy magnet is usually 8-13wt% aluminum, 13-28wt% nickel, 5-24wt% cobalt, and the rest is iron. In addition, the enhancement of acicular phase is promoted to improve the intrinsic coercivity, and alloy elements such as copper, titanium and niobium are added to the matrix phase. Aluminum Nickel Cobalt(AlNiCo) magnets once occupied a dominant position in the permanent magnet industry before the birth of rare earth magnets with their strongest magnetic properties. Alnico magnet is famous for its excellent heat resistance / temperature stability, hard and brittle materials, and it is also a magnet with low to medium strength.
AlNiCo magnets perform well in applications with operating temperatures above 400 degrees According to the manufacturing process, AlNiCo magnets can be divided into cast AlNiCo magnets and sintered AlNiCo magnets.
