Alnico magnet is the earliest developed permanent magnet material, which is an alloy composed of aluminum, nickel, cobalt, iron, and other trace metal elements.
Neodymium disc magnet with 3M adhesive, can be easily fixed to non-metallic surfaces with adhesive. Because the adhesive is not resistant to high temperatures, please use it at normal temperatures.
Alnico magnet is the earliest developed permanent magnet material, which is an alloy composed of aluminum, nickel, cobalt, iron, and other trace metal elements.
Neodymium bonded magnets are typically made by mixing neodymium powder with a polymer binder such as epoxy or nylon. This mixture is then molded into the desired shape and cured to form a solid magnet. The binder helps hold the neodymium powder together and provides stability and durability to the magnet.
The advantage of Alnico magnets is high remanence (up to 1.35T), but it is easy to be magnetized and demagnetized. Do not contact ferromagnetic substances during use
