Alnico magnets have the best temperature coefficients of any magnet material. Alnico magnets are a best choice in extremely high temperature applications. Alnico magnets are Cast or Sintered. They are an alloy of Aluminium, Nickel and Cobalt hence the term Al-Ni-Co.
Alnico magnets have the best temperature coefficients of any magnet material. Alnico magnets should be regarded as the best choice in extremely high temperature applications. They can be produced by Casting or Sintering. Cast Alnico is the most common form of Alnico magnet. Casting is often used to get “near net shape” Alnico magnets. Casting Alnico is cost effective for both low and high volume, for small and very large magnets. Sintered Alnico magnets are not so commonly used due to lower magnetic performance and limitation to simpler shapes. Anisotropic magnets have the direction of magnetisation (DoM) permanently within the structure and give the maximum performance.
