Neodymium disc magnets have unique features and characteristics that make them highly sought after for various applications. Here are the key features:

1. Strong Magnetic Strength: Neodymium magnets have magnetic properties that far exceed all other permanent magnet materials. They are known for their exceptional strength and can generate powerful magnetic fields.

2. Wide Range of Grades: Neodymium disc magnets are available in a wide range of grades, ranging from N30 to N54. N54 is the highest grade available in the market, offering the strongest magnetic strength.

3. Various Sizes and Shapes: Neodymium disc magnets come in a variety of sizes and shapes, including micro-sized discs measuring as small as 1mm diameter and larger cylinder magnets that can hold up to 30kgs. This wide range of options allows for versatility in different applications.

4. High Temperature Resistance: Neodymium magnets can perform well in ambient temperatures. However, it is important to note that they have a temperature limit and should not be used above certain temperatures, typically around 80°C, to maintain their magnetic properties.

5. Axial Magnetization: Neodymium disc magnets are typically magnetized axially, meaning the magnetic field runs through the thickness of the magnet, with each pole located on the flat surfaces of the disc. This magnetization orientation provides optimal magnetic strength.

6. Durable and Corrosion Resistant: Neodymium disc magnets are sintered for optimal magnetic strength and can withstand various environmental conditions. They can be left uncoated or can be coated with finishes such as nickel (Ni-Cu-Ni) or gold (Ni-Cu-Ni-Au) plating to provide maximum protection against corrosion and oxidation.

7. Versatile Applications: Neodymium disc magnets have remarkable holding power for their size, making them ideal for a wide range of applications. They are commonly used in industries such as electronics, electrical machinery, medical equipment, motors, speakers, magnetic therapy, DIY projects, and more.

These features make neodymium disc magnets highly valued in both industrial and consumer markets for applications demanding strong, compact, and durable magnetic solutions.
