Description: 5pcs N52 Rectangular Block Magnets 15x6x3mm Rare Earth Neodymium Magnets Neodymium (chemical symbol Nd) is element 60 on the periodic table. It is a rare earth metal and forms one of the Lanthanides series. When added to Iron (Fe) and Boron (B) (chemical formula Nd14Fe21B) the resultant magnets are the strongest magnets currently available. Neodymium magnets are sometimes known as Neo, Neod or NIB magnets. Neodymium magnets are usually coated Nickel-Copper-Nickel plating to prevent the iron from rusting. Usually placed in room temperature, the maximum operating temperature is 80 C and it never will demagnetization. Specification: Shape: Block Cuboid Grade: N52 Size: 15mm x 6mmx 3mm Plating: Ni-Cu-Ni ( Nickel ) Material: NdFeB Color: Silver Quantity: 5 pcs Max Operating Temperature: 80C/176F Features: Can also be used to extend protected lithium batteries with recessed contact points. Electrically conductive (making them suitable to extend recessed batteries). Perfect for sticking notes on fridge doors. Great for DIY projects.
