Aluminum, Nickel, Cobalt (referred to as Alnico) is manufactured by traditional foundry casting or sintering techniques developed in the 1930’s. This kind of material offers the best temperature coefficient (0.02% per degree centigrade) of all permanent magnets making it an ideal choice when a constant field over a wide temperature range (‐270°C to +500°C) is required.
The high nickel content results in good stability against corrosion and oxidation. However, Alnico magnets are a low coercive force material and most times should be magnetized after assembly. The performance can be affected by mishandling or exposure in other magnetic fields.
