• Composition - Neodymium magnets are composed of neodymium (Nd), iron (Fe), and boron (B). The combination of these elements results in a crystalline structure that contributes to the high magnetic properties. However, this crystalline structure also makes the magnets less hard than other carbon steels.
• Feature - Various sizes can satisfy your various choices. We provide the perfect size for a variety of applications. These magnets have a triple layer coated with Nickel+Copper+Nickel to provide shiny and durable protection.
• Applications - These magnets are used for educational, research, professional, commercial, or industrial purposes that are sold or distributed to school educators, researchers, professionals, or commercial or industrial users.
• Tips- Magnets can attract to each other with great force, so avoid dropping them or subjecting them to impacts.
