Product Description
LNG48/LNG60 Customized High Temperature Resistance Rare Earth Permanent Alnico Magnets
Product Description
Alnico magnets are made of an alloy of aluminum, nickel and cobalt. They are very used magnets in the industrial
sector, thanks to their properties and their resistance to high temperatures. They are the magnets with more stability
at extreme temperatures, for this reason we can find them inside ovens making the function of subjection or detection.
The Alnico magnet is the magnetic element with the highest stability at extreme temperatures, that is, it maintains
all its magnetic properties between -250ºC and 425ºC, ensuring a high thermal resistance. (In the case of neodymium
magnets, the maximum working temperature is 200°C)
This alloy composed of aluminum, nickel and cobalt, has a high level of magnetic induction but a lower coercivity.
Although new stronger materials and cheaper solutions have emerged, alnico magnets continue to incorporate a
special property, have a lower coercive field that enables magnetization and demagnetization, with low power.
The magnetic orientation of these products must be carried out during their heat treatment, ensuring a magnetic field
with the direction of magnetization defined. The force that alnico magnets can provide is the most similar and comparable
to neodymium magnets.
Another great advantage is its resistance to chemical products, such as acids or solvents, and its good oxidation behavior.
The horseshoe Alnico magnet is the best known product thanks to its design that is assigned to describe a conventional magnet.
