Key Features:

1. Material Composition:
   • Made from a combination of neodymium (Nd), iron (Fe), and boron (B), these magnets are commonly referred to as NdFeB or neo magnets.
   • The material is sintered or bonded to achieve high magnetic strength.
2. Magnetic Strength:
   • The rectangular NdFeB magnet offers incredibly high magnetic strength relative to its size. For example, an N52 grade magnet has one of the highest energy products, delivering a magnetic field strength of up to 1.4 Tesla.
   • These magnets are axially magnetized, meaning their magnetic poles are on the larger rectangular surfaces.
3. Coatings:
   • Rectangular NdFeB magnets are typically coated with materials like nickel (Ni), zinc (Zn), or epoxy to prevent corrosion and wear, making them durable in various environments.
4. Available Sizes:
   • Available in a range of dimensions, from very small (a few millimeters) to larger magnets, allowing for versatility across different applications. Common sizes include 20×10×5mm, 50×25×10mm, or custom sizes based on user needs.
5. Grades:
   • NdFeB magnets come in various grades, with N35, N42, N50, and N52 being the most common. The higher the grade, the stronger the magnetic field.
6. Temperature Resistance:
   • Standard NdFeB magnets can operate in temperatures up to 80°C (176°F), while specially designed variants can handle higher temperatures without significant loss of magnetism.
