Technical Drawing
Areas of application
Neodymium block magnets are made of the powerful neodymium-iron-boron (NdFeB) alloy and offer exceptionally high adhesive force compared to conventional ferrite or AlNiCo magnets. The combination of impressive magnetization capability and high flux density makes neodymium one of the strongest magnetic materials on the market. These properties are ideal for applications that require high magnetic force in a small space:
- Industry and production: Neodymium block magnets are often used in industrial manufacturing and assembly to hold components in place. Thanks to their high adhesive force, they hold machine covers, tools and metallic components securely in place. They are also ideal for locking systems, such as cabinet or door magnets.
- Events and presentations: At trade fairs, exhibitions and presentations, neodymium block magnets provide an easy way to securely and flexibly attach posters, signs and presentation materials. Their small size allows for unobtrusive attachment without damaging the material.
- Furniture and interior design: Neodymium block magnets are popular in furniture making for integrating concealed magnetic closures into cabinet doors and drawers. In interior design, they are used to attach panels and covers, where they are visually discreet yet extremely strong.
- Electrical engineering: Neodymium magnets play a central role in electrical engineering, particularly in the field of electromobility. They are installed in the electric motors of cars and bicycles, where they enable the rotation of the motors through the interaction of magnetic fields and electric current.
In addition, magnets are used in loudspeaker technology: in combination with a current-carrying coil, they generate sound waves in the loudspeaker by causing membranes to vibrate, thus making sounds audible. Their versatile application possibilities make magnets an indispensable component in modern technical systems.
