This listing includes a top quality AlNiCo magnet which is made of AlNiCo 5 material. This magnet is 1/4" square and 1/2" long and magnetized through 1/4" so the N and S poles are on the 1/2x1/4" surfaces. This magnet has a holding of 1.34 lbs.
AlNiCo magnets have an extrodinary temperature stability than the other types of magnets so it is mostly used in the industries like high temperature tooling or oil fields where high temperature is present.
Generally speaking, AlNiCo magnets are more fragile than neodymium magnets. AlNoCo magnets have a better machinability so it can be made with higher precision. It also exhibites a better conductivity than the other types of magnets. There is no coating for this magnet. The following is the magnetic characteristics of this magnet.
- Material: AlNiCo class 5
- Magnetic Characteristics: Br: 1,200mT, Hcb: 48kA/m, BH: 37KJ/m³
- Holding Power:
- Pole Orientation: Magnetized through 1/4", i.e. the north and south poles are on the 1/2x1/4" surfaces
- Tolerances: 1/2 +/-0.004" x 1/4 +/-0.004" x 1/4 +/-0.004"
- Maximum Normal Operating Temperature: 550 degree C or 1,022 degree F (5% loss of the magnetism at this temperature)
