Description
HIGH QUALITY: Made from strong neodymium-iron-boron alloy (NdFeB) and have a stylish nickel coating (Ni-Cu-Ni) with an appealing silver surface — All the magnets are magnetized axially and have a maximal operating temperature of 80 degrees Celsius
MULTIPURPOSE: These neodymium magnets are perfect for DIY craft projects and scientific projects
LARGE SIZE: Diameter 40mm x thickness 20mm(approx.1.57″x0.79″ ).Tolerances: ±0.2mm x ±0.2mm. Stronger magnetic properties and wider applications than ordinary magnets
USAGE TIPS: Neodymium magnets are not actually made of solid blocks of metal, but rather large amounts of powder pressed into blocks through a process called sintering. When subjected to a sudden impact, they will break. To prevent the magnets from breaking, the two magnets should be separated by a large distance to prevent them from being attracted and collided.
PURCHASE TIPS: If you want a stronger magnet, you can rotate and buy 2 magnets. The combination of two magnets has a stronger magnetic force. The maximum pulling force of one is 125 pounds, and the maximum pulling force of two together can reach 250 pounds
