What is an N52 magnet?

N52 magnet is neodymium magnet which containers energy product or (BX) Max of 52MGOe (Mega-Gauss Oersteds). The “N52” is an abbreviation referring to the strength of this magnet.

● Is N52 the strongest magnet?

Neodymium is the strongest rare earth magnet material, and N52 is among the highest grades of neodymium. Consequently, N52 magnets are some of the strongest magnets on the planet.

The number abbreviation, N35, N42, N52, for example, indicates the strength, or energy product, of the magnet grade. An increase in the number associated with the grade represents an increase in the magnets energy products.

● What Applications merit an N52 magnet?

With a high strength-to-size ratio, N52 magnets are often used for applications that require a small but strong magnet, such as electronics, scientific applications, households as latches that require securely held components.

However, strength isn’t the only factor that should be considered when choosing the desired grade of magnets.

Some customers mistakenly specify N52 neodymium magnets based only on the material’s high energy product. They may assume a stronger magnet grade will yield better performance, but this is no always the case. The force that an N52 magnet can hold will vary depending on a wide variety of factors.

● What other factors should be considered when choosing an N52 magnet?

Although higher energy product material is typically stronger than lower energy product material, N52 magnet strength and the value of its (BH) Max is not the only criteria for selecting material grade.

The following factors should also be considered:

○ Operating temperature

○ Magnet geometry

○ Application requirements

○ Cost and value

● Why consider cost when choosing N52 magnets?

Many of our customers are surprised to learn that the performance characteristics of N52 may exceed the required application specifications by a significant margin. N52 neodymium magnets are produced from one of the most expensive grades of neodymium; in some instances, a lower grade will perform effectively for a significantly lower price. We provide consultation to support you for making the right decision for your application.

● What problems can occur with N52 magnets?

Problems with N52 magnets can often be attribute to utilizing other suppliers with standards that allow alloy impurities.Therefore, it is critical to properly qualify suppliers prior to ordering.

The figure below illustrates a non-traditional dip in the BH curve, indicative of impurities in the magnetic alloy.

● How can you ensure superior quality N52 magnets?

To ensure proper quality grade, we verifies performance by testing samples from each delivery, and every orders are sent with PSI documents.

If a client doubts of the quality, our comprehensive in-house testing and analysis qualifies an existing material type, and our team recommends the most appropriate magnet if an alternative is available.
