About the product
- HIGH QUALITY: Made from 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. 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:DO NOT attempt to pry or pull magnets apart with direct force, as this will break them.Correct method: To separate, gently slide the magnet off the edge of the other magnet or steel surface. For larger blocks, use non-magnetic tools (plastic or brass shims) as spacers to control movement
