Alnico is an acronym to the iron alloys which in addition to iron are composed largely of aluminum (A), nickel (Ni) and cobalt (Co), hence alnico, with the addition of copper, and sometimes titanium. Alnico magnets are largely comprised of Iron, Cobalt, Aluminum, and Nickel with trace amounts of other elements used to tailor the alloy’s magnetic and mechanical properties. Alnico magnets are the ferromagnetic in nature and are use to make permanent magnets. A To Z Magnet provides you a wide range of accurate ground bar magnets, which are manufacture from Alnico that provides a higher resistance to the corrosion and a higher temperature rating that goes up to 500 °C.
The surfaces of cast Alnico magnets are usually dark grey, have wide tolerances, and have a rough finish. A To Z Magnet gives you high quality Alnico magnets that are use for various purposes such as –:
These alnico magnets come in different shapes and sizes. Usually size parameters have ranges from 1 ounce to 70 pounds. Sintered Alnico magnets made from powdered mixture of ingredients pressed into close tolerance\minimal grinding to finish.
Alnico magnets are the most temperature stable and idle for high heat applications with maximum working temperature of 975 F to 1020 F. May be ground to size but does not lend itself to conventional machining (hard and brittle). It also has high residual induction and energy product compared to ceramic material.
Low coercive force compared to ceramic and rare earth materials mainly subjected to demagnetization. Most popular and the most common grades of alnico magnets are 5 and 8.
