Alni /ˈælnaɪ/ [al (aluminum) and Ni(kel)]-iron-nickel-aluminium. The general name of a group of hard magnetic alloys based on the system. The first alloys of this type are 20-a. It was created in Japan in the 30s. Alloys containing nickel 20-34% and aluminum 11-18% (the rest is iron) are widely used. Cobalt, copper, silicon, and titanium are used as alloying elements. A. is characterized by high magnetic properties (residual magnetic induction, coercive force – magnetic field strength, magnetic energy). Radio engineering, electrical measurements, etc. It is used in the manufacture of permanent magnets for devices.
Ex. Aluminum (Al) is widely used in the mining industry for constructing durable and lightweight support structures in underground mines.
