High-quality material: Magnetastico magnets are made of NdFeB (neodymium-iron-boron-alloy) with the highest N52 magnetisation possible. So called rare earth magnets are real power packs with strong magnetization. These powerful neodymium magnets (super-magnets) can be used in your kitchen, bathroom, office, for crafts, on your magnetic pin board & in many other areas in the home, office & in hobbies. Neodymium permanent magnets are also used for science, innovation, engineering & industry. Scope of delivery: You get 100 pieces with 6x2 mm (diameter x height) disc-shaped neodymium magnets (disc magnets / magnetic discs / cylinder magnets). These disc magnets are axially magnetised throughout their thickness i.e. height. That means that the magnetic North Pole and the magnetic South Pole are located on the neodymium magnet ‘s large surfaces. High-quality magnet coating: Magnets have three coats of nickel-copper-nickel (NiCuNi) and thus a smooth, silvery surface for high loadbearing capacity and relative inurement to external influences (such as corrosion) are achieved! Nevertheless, these magnets are not indestructible and should be used with care. The alloy could suffer harm if these extra strong magnets strike each other. Highly versatile: N52 magnetic strength guarantees an extremely high adhesive force. Even multiple layers of photos, postcards, business cards, tickets, calendars, budgetary plans, newspaper articles or paperclips can be held fast to your refrigerator, your fridge door, your whiteboard, your magnetic board (magnetic notice board), wall or board, your magnetic track, pin-board, white board & white wall board, your magnetic rope or other metal surfaces (such as iron, steel, tin). Magnetastico brand quality: Like all other Magnetastico magnetic products these strong neodymium magnets are also high-grade everyday companions at work, in the office as office magnets, for handicrafts and in the repair shop as holding and lifting magnets with an almost unlimited range of uses! For their size these neodymium magnets provide a very high adhesion force (nothing compared to normal, weak ferrite magnets) and are no toys!
