Description

PERMANENT MAGNETS

AlNiCo is an acronym referring to a family of iron alloys which in addition to iron are composed primarily of Aluminium (Al), nickel (Ni) and cobalt (Co), hence Al-Ni-Co. They also include copper, and sometimes titanium. AlNiCo alloys are ferromagnetic, with a high coercivity (resistance to loss of magnetism) and are used to make permanent magnets.

AlNiCo's remanence (Br) may exceed *3,**0 G(1.*5T), its coercivity (Hc) can be up to ***0 Oersted (**8 kA/m), its energy product ((BH)max) can be up to *2 MG·Oe (*6k·A/m).

AlNiCo alloys have some of the highest Curie temperatures of any magnetic material, around **0 °C (1,**0 °F), although the maximum working temperature is normally limited to around **8 °C (1,**0 °F). They are the only magnets that have useful magnetism even when heated red-hot.

Provide whole series of AlNiCo permanent magnets, in the shape of cylinder, cube, ring and any special form requested. Allowable error could be controlled in 0.**5mm.
