Detailed information

Alnico is mainly made up of aluminum, nickel, cobalt, iron, copper, titanium and other materials, and is divided into two categories according to the difference of processing technology.

The cast Alnico has higher magnetic property than sintered Alnico, but sintered Alnico is simpler in manufacturing process.


Property:

In the open magnetic circuit, the ratio of length to diameter of the alnico is at least 4:1, and if the ratio is less than 4:1, the magnetic property is very unstable;

Alnico has good corrosion resistance property and does not require surface coating treatment;

Alnico has the lowest Br reversible temperature coefficient, which is -0.02% / °C, so its temperature stability is great;

The maximum working temperature can reach 400 °C.


Application fields:

Hall components for temperature sensor, electronic sensor for automobile;

Magnetron, TWT amplifier, regulator, motor and meter;
