What You Should Know About N52 Magnets

What is an N52 magnet?
An N52 magnet is a high-energy magnet made of neodymium-iron-boron (NdFeB), a rare earth material. It is one of the most powerful magnets in the world and is renowned for its exceptional performance.

Is N52 the strongest magnet?
N52 NdFeB is the highest grade in terms of magnetic strength among neodymium magnets, and it also has high temperature resistance, with a maximum ambient temperature of up to 200°C. For example, the numerical abbreviations N35, N42, N52 represent the strength or energy product of the magnet grade. An increase in the number associated with the grade indicates an increase in the magnet's energy product.

Applications of N52 magnets
N52 magnets, with their high strength-to-size ratio, are typically used in applications that require small yet powerful magnets. Examples include electronics, scientific applications, and household items such as door locks that require securely fixed components. However, strength is not the only factor to consider when selecting the required magnet grade. Some customers mistakenly specify N52 neodymium magnets solely based on their high energy product. They may assume that a stronger magnet grade will result in better performance, but this is not always the case. The force that an N52 magnet can withstand can vary due to multiple factors.

What other factors should be considered when selecting N52 magnets?
While high energy product materials are generally stronger than those with lower energy products, the strength of N52 magnets and their (BH)Max values are not the sole criteria for selecting a material grade. Factors such as operating temperature, magnet geometry, cost, and value must also be taken into account.
