Alnico is an abbreviation of the first 2 letters of three metallic elements. The three metallic elements are aluminum, nickel and cobalt. In early of 1930’s, Japan invented an alloy of iron, nickel and aluminum. This alloy is two times stronger than rolled steel. People shortly found that the alloy owned super strong resistance to corrosion after adding cobalt. And the iron alloy with added Alnico has extremely strong heat-resistance, and doesn’t lose magnetism easily. Therefore, this kind of alloy was applied in manufacturing of permanent magnet.
Owing to the superior heat-resistance and durability, Alnico magnets are widely spread in various applications like electricity motors, sensors, microphone, and pickup and etc. A typical application of Alnico rare earth magnet is used for electric guitar pickup. The structure of pickup is composed of alnico magnet and coil. High quality alnico magnet is very suitable for making electric guitar pickup. Alnico magnet makes pickup possessing warm and smooth high quality tone. There are different types of Alnico pickup. They are marked simply by roman numbers, such as Alnico II,Alnico III and Alnico V, namely Alnico2, Alnico3 and Alnico5. Different numbers indicates different magnetic strength, and different ratios of all kinds of elements. Alnico V is the most powerful one with better tone and frequency response.
