Examples of alnico
alnico
A magnet made of alnico, an iron alloy.
From the en.wikipedia.org
Alnico magnets resist corrosion and have physical properties more forgiving than ferrite, but not quite as desirable as a metal.
From the en.wikipedia.org
Alnico permanent magnets based partly on nickel are of intermediate strength between iron-based permanent magnets and rare-earth magnets.
From the en.wikipedia.org
A magnetic pickup consists of a permanent magnet with a core of material such as alnico or ceramic, wrapped with a coil of several thousand turns of fine enameled copper wire.
From the en.wikipedia.org
The development of alnico began in 1931 when it was discovered that an alloy of iron, nickel, and aluminum had a coercivity double that of the best magnet steels of the time.
From the en.wikipedia.org
Alnico magnets are made by casting or sintering a combination of aluminium, nickel and cobalt with iron and small amounts of other elements added to enhance the properties of the magnet.

- Trade name for an alloy used to make high-energy permanent magnets; contains aluminum and iron and nickel plus cobalt or copper or titanium
- Alnico is an acronym referring to iron alloys which in addition to iron are composed primarily of aluminium (symbol Al), nickel (symbol Ni) and cobalt (symbol Co), hence al-ni-co, with the addition of copper, and sometimes titanium. ...
- For medium strength and excellent machinability. Developed in the 1940s and still in use today. They perform much better than plain steel, but are much weaker in strength (lower B, Br and BHmax) and must be carefully stored since they are prone to demagnetization. ...
