Our aluminum nickel cobalt magnets are made from aluminum and cobalt alloys, designed for heavy-duty use with excellent resistance to demagnetization over time. These magnets are ideal for lifting, holding, sorting, clamping, or retrieving steel and iron parts. They can also be used for fishing, measuring, collecting small metal screws, conducting experiments, and other applications. These horseshoe-shaped magnets feature a hole at the top for easy attachment to conveyor belts, racks, welding fixtures, and similar setups. A removable retainer helps preserve magnetic strength. Safety Notes: 1. Keep away from pacemakers. 2. If damaged or decomposed, discard immediately. 3. Strong magnetic properties—handle with care to avoid pinching fingers.
