GEOLOGY

Detailed explanation-1: -Alnico is a family of iron alloys which in addition to iron are composed primarily of aluminium (Al), nickel (Ni), and cobalt (Co), hence the acronym al-ni-co. They also include copper, and sometimes titanium. Alnico alloys are ferromagnetic, and are used to make permanent magnets.

Detailed explanation-2: -Alnico magnets are made primarily from aluminum, nickel, cobalt, copper, iron and sometimes titanium. They can be either cast or sintered.

Detailed explanation-3: -While alnico magnets have largely been replaced by stronger rare-earth magnets, alnico are still commonly used in the manufacturing of sensors, guitar pickups, relays and high temperature handling equipment.

Detailed explanation-4: -Permanent magnets are made from special alloys (ferromagnetic materials) such as iron, nickel and cobalt, several alloys of rare-earth metals and minerals such as lodestone.

Detailed explanation-5: -Alnico is an alloy made mainly from a combination of Aluminium, Nickel, Cobalt and Iron plus varying levels of Copper, Titanium and Niobium. The exact chemical composition within Alnico grade depends on the grade of Alnico.
