Product Description

We produce Sintered Alnico magnet since ***1.Alnico is an acronym referring to metal alloys which are composed primarily of aluminium (symbol Al), nickel (symbol Ni) and cobalt (symbol Co), hence al-ni-co, and iron, with the addition of copper, and sometimes titanium. Alnico alloys are ferromagnetic, and used to make permanent magnets. Before the development of rare earth magnets in the ***0s, they were the strongest type of magnet. Other trade names for alloys in this family are: Alni, Alcomax, Hycomax, Columax, and ***** composition of alnico alloys is typically 8~*2% Al, *5~*6% Ni, 5~*4% Co, up to 6% Cu, up to 1% Ti, and the balance is Fe. A high working temperature limit (**0 C / ***0 F) makes Alnico especially well suited for sensitive automotive and aircraft sensor applications. Other popular Alnico applications include: Instruments, security sensors, magnetos, electronic distributors, separators, electron tubes, traveling wave tubes, radar, holding magnets, coin acceptors, generators and motors, clutches and brakes, relays, controls, receivers, telephones, microphones, bell ringers, guitar pickups, loudspeakers, security systems, cow magnets. Alnico is produced in many grades to fit the requirements of these applications, from Alnico 1 to Alnico *2, but the most popular grades are 2, 5 and 8. By comparison to newer materials, like ceramic, Nd-Fe-B and Sm-Co the coercivity of Alnico is low, so they have replaced Alnico where cost and/or greater resistance to demagnetization are valued more than a high temperature limit and temperature stability.
