Permanent Alloy Magnets price Permanent magnet AlNiCo is an alloy of iron in which aluminum, nickel, cobalt, and a small amount of other magnetic enhancing ingredients are added in addition to iron.AlNiCo alloy has high coercivity and high Curie temperature. AlNiCo block magnet is hard and brittle and cannot be cold worked. It must be made by casting or sintering process. AlNiCo can produce a magnetic field of up to 0.15 Tesla. For an example of an intermediate anisotropic cast Al nickelco alloy, the composition of AlNiCo-6 is 8% Al, 16% Ni, 24% Co, 3% Cu, 1% Ti, and the rest are Fe. AlNiCo-6 has a BHmax of 3.9 megagauss-oesteds (MG路Oe), a coercivity of 780 oersted, a Curie temperature of 860 掳C, and a maximum operating temperature of 525 掳C.Before the discovery of rare earth magnets in the 1970s, AlNiCo was the strongest material for permanent magnets. AlNiCo block magnet has the advantages of high remanence (up to 1.35T), low coercivity (usually less than 160kA/m) and nonlinear demagnetization curve, so AlNiCo block magnet is easy to be magnetized, but also easy to demagnetize. Special attention should be paid to its particularity in the design and manufacture of magnetic circuit of devices, and the magnet must be stabilized in advance. It is strictly prohibited to contact with any ferromagnetic material during use, so as not to cause local irreversible demagnetization or distortion of flux density distribution. Among all permanent magnet materials, AlNiCo block magnet has the lowest reversible temperature coefficient. AlNiCo block magnet has good temperature stability and aging stability, and is suitable for making instruments, motors, electroacoustic devices, magnetic machinery, etc. Our AlNiCo magnets are all REACH and ROHS compliant and don鈥檛 contain any SVHC. It is produced according to ISO 9001 and ISO 14001 Quality Control Standards. PPAP, APQP, CPK/PPK, 8-D, CO, FTA are available.
