Neodymium magnets are the strongest type of permanent magnet currently available. They are amazingly powerful for their size and have many applications. These magnets are 1/2 inch (0.5) x 3/8 inch (0.375) disc. They are composed of a grade 45 alloy of neodymium, iron, and boron and are plated in nickel-copper-nickel for a shiny corrosion resistant finish. Their individual pull force is approximately 16.8 lbs. Notes: 1. All magnets are fragile. The stronger the magnets the easier they break when collide together. These magnets may snap if collide together or to a steel surface. Hold and release slowly when apply. If used properly, these magnets can serve you for lifetime. 2. Keep them away from children under 8 years old. Also keep them away from pacemakers and any other physical devices.
