Description

Strong Power Alnico 8 Bar Magnet

Alnico Magnet

These magnets are based mainly on iron (Fe), aluminum (Al), nickel (Ni) and cobalt (Co). The magnets are fragile
and not ductile. Therefore, after the raw metal is melted at high temperature and turned into an alloy, it is cast into a
casting mold. These magnets are therefore also known as cast magnets.Al-Ni-Co magnets achieve high Br values and
high temperature stability, readily cause low-temperature demagnetization and thermal demagnetization, achieve
high mechanical strength, and offer other advantages. However, these magnets have low magnetic coercive force
and readily undergo demagnetization due to an external magnetic field, are unsuited for thin products, and placed
under other constraints. In the design process, it is therefore important to select a method of magnetization
that allows for sufficient shape and magnetic characteristics, and a method of assembly in
which consideration is given to demagnetization.

Produced by casting or sintering powder metallurgical technique with alloy composite of Al-Ni-Fe-Co

Alnico is a very hard and brittle material and does not lend itself to conventional machining.
UNMAG have experienced machinists and the proper equipment to grind alnico to its required dimensions.

Characteristic of Both Cast and Sintered Alnico magnet


Very temperature stable, great for high heat applications
Maximum working temperature 450-550°C
Does not lend itself to conventional machining (hard and brittle)
High residual induction and energy product compared to ceramic material
Low coercive force compared to ceramic and rare earth materials (more subject to demagnetization)
Most common grades of alnico are 5 and 8
Not suited for repelling or high friction applications
