Alnico Magnet

Send Message Request a Quote

The alnico magnet is an alloy composed of aluminum, nickel, cobalt, iron and other trace metals. The component percentage of the metal elements determines the magnetic properties and the applications of the product.

There are two manufacturing methods, casting and sintering. Through casting, alnico magnet of different sizes and shapes can be obtained. The sintered product is relatively small in size, but its dimensional tolerance is less than that of the cast product.

The alnico magnet has the lowest reversible temperature coefficient among all magnets and its operating temperature can reach 500℃ and higher. It is widely used in the teaching, aviation, electronic, automobile, electromechanical, medical treatment, military technology, and other fields.

Our products are mainly sold to auto parts manufacturers in the US and Germany. We have established a good and stable cooperative relationship with BOSCH and other world-renowned enterprises. If you have any questions or needs, please feel free to contact us.
