Sintered Alnico Magnets – Alnico is composed primarily of aluminum (Al), nickel (Ni) and cobalt (Co). Alnico alloys are ferromagnetic, with a high coercivity (resistance to loss of magnetism). Before the development of rare earth magnets in the 1970s, they were the strongest type of magnet.
RoHs and DFAR Compliant Materials are available off the shelf in different configurations.
Alnico magnets produce magnetic field strength at their poles as high as 1500 gauss which is about 3000 times the strength of Earth’s magnetic field and are the only magnets that have useful magnetism even when heated red-hot.  AlNiCo Rod Magnets
Some types of alnico are isotropic and can be magnetized in any direction. Other types, such as alnico 5 and alnico 8, are anisotropic, having a preferred direction of magnetization, or orientation. Anisotropic alloys generally have greater magnetic capacity in a preferred orientation than isotropic types.

Alnico magnets are manufactured using primarily two processes:
Cast Alnico Magnets and Sintered Alnico Magnets

Sintered alnico magnets are made from a powdered mixture of ingredients that are pressed into a die under tons of pressure.
They are then sintered in a hydrogen atmosphere and cooled in an anisotropic or isotropic environment.
Attributes of Sintered Alnico Magnets
* Mechanically strongest of the Alnico Magnets
* Close tolerance pressing – typically minimum grinding
