Alnico permanent magnet products are widely used in various instruments and other applications.

Alnico magnets are made from aluminum, nickel, cobalt, copper, iron, titanium and other element. There is cast or sintered Alnico magnet due to different process craft.
Casting process can be processed production into different sizes and shapes;
Cast aluminum nickel and cobalt with low temperature coefficient, operating temperature up to 550 degrees Celsius.
resistant to heat and moisture, not easy to oxidized, and working stability is the best,it is graet for high heat applications

The advantages of the Alnico magnet remanence (up to 1.33T), low temperature coefficient. The temperature coefficient of -0.02% / ° C, while the maximum operating temperature up to about 550 ℃.
Shortcoming: the coercivity is very low (typically less than 140kA / m), demagnetization curve is nonlinear. Alnico magnets easily magnetized, also easy to demagnetization.

Applications:
auto parts,
instrumentation,
