Product Name: Strong Permanent Disc AlNiCo Magnets Model NO.: SM-A05 Grade: FLNGT18 Coating: Nickel, Zn, Black Epoxy, AG, Au etc. Application: Industrial Magnet Shape: as Customer's Request Type: Permanent Composition: AlNiCo Magnet Trademark: OEM Transport Package: Carton, Pallet Specification: As customer's request Origin: China HS Code: 8505119000 Product Description Alnico magnets are made primarily from aluminum, nickel, cobalt, copper, iron and sometimes titanium. The composition of alnico alloys is typically 8? C12% Al, 15? C26% Ni, 5? C24% Co, up to 6% Cu, up to 1% Ti, and the balance is Fe. They can be either cast or sintered. Cast alnico magnets is melted and and poured into a mold. once solidified, the material is rough ground and then heat-treated and cooled, sometimes in a magnetic field. When treated in the presence of a magnetic field, the magnet is called anisotropic. This orients the material to take on maximum magnetization and allows a higher gauss level. A cast alnico magnetthat is not heat-treated in a magnetic field is called isotropic. After heat treatment and cooling, the material can be ground to specific tolerances and then magnetized.Magnetic Properties of Cast AlNiCo MagnetsGradeRemanence BrCoercivity Force HcbMax.
