The top 10 tings you need to know about N52 magnets？

1.What is N52 magnet？

N52 is the performance grade of neodymium permanent magnets material. The letter “N” in N52 means this is neodymium and the number “52” is the maximum energy product (BH max) of 52 MGOe. The maximum energy product of permanent magnet is measured in MGOe (Mega Gauss Oersteds). This is one of the main performance indicators that identifies the magnetic strength of a permanent magnet. Generally, the higher the (BH)max value, the greater the magnetic field generated by the magnet in a given application. N52 grade is recognized as having the best magnetic properties and is the most widely used.

2. What is the pulling force of an N52 magnet?

The pulling force of a magnet is how much force is needed to pull the magnet and move it away from a surface of another magnet. The pulling force is measured in kilograms and usually varies with the N number of the magnet.

For example, if the N52 magnet is 12.7 mm in diameter and 12.7 mm thick, the pulling force would be about 9 kg. However, if the diameter and thickness are doubled (25.4 mm), the pulling force will be about 35 kg. A pull force calculation to measured the pulling force is available on our website, if you want to try it, please click on this link.

3. What is the surface field magnetism of the N52 magnet and what is the strength of the N52 magnet? What is the working temperature of the magnet?

The surface magnetism is the magnetic induction strength at a certain point on the surface of the magnet, the unit is Gauss Gs or Tesla T (1T=10000Gs), the number of Gauss can be reach on the surface magnetism of N52 NdFeB magnet depends on the size, shape and grade of the magnet. And the factor is slightly different according to the requirements of different customer, generally the residual induction of N52 is 14.2~14.7KGs. The maximum working temperature of N52 magnets is 80 degrees Celsius.

4.Are N52 magnets the strongest magnets?

No, there are other higher grade magnets above N52, such as N54. But N52 is the strongest and most commonly used magnet in the market.

5.What are the applications of N52 magnets?

N52 magnets are generally used inside products with high magnetic properties and low size ratio. For example, electronic products, scientific experiments and household products. Our products are mainly used in motors, sensors appliances, communication equipment, electronic appliances industries.

6、How do I choose an N52 magnet?

Magnetic properties are not the only factor that should be considered when we are choosing a strong magnet of the required grade. Many customers will ask for N52 magnets, and they think the stronger the magnet grade is, the better. In fact, when choosing a magnet, we should consider other factors, such as working temperature, cost, magnetic properties and other factors to choose a magnet that is low cost and suitable for your product

7. Are N52 magnets suitable for my product?

In some cases, the performance of the N52 may exceed the performance required for its application. Other grades such as N35 or N38 may also meet performance requirements, depending on the temperature, shape and application of the magnet.

8. What are the characteristics of N52 magnets?

Its main characteristics are high maximum magnetic induction strength, high magnetic energy density, high tensile strength, good plasticity, etc. 

N52 magnet parameters are: 

magnetization strength: maximum magnetic induction strength (Br) up to 12000-13000 gauss; 

magnetic energy density: up to 120 kJ/m3; 

tensile strength: up to 270 MPa; 

plasticity: good plasticity, can be shaped at very low temperatures; 

thermal stability: good thermal stability, can withstand 80 ℃ Magnetic loss: magnetic loss is very small, can ensure the permanence of magnetic properties 

Corrosion resistance: good corrosion resistance, which can be applied to many different environments.

9. Price of N52 magnets? How to buy magnets?

Many customers are curious about the price of N52 magnets, and we usually quote according to the customer's requirements. However, sometimes the price of magnets fluctuates due to the increase in the price of rare earths material in the market. So the price of magnets are not fixed. At the same time, the size, plating, and moq of the magnet required by the customer are different, and the price we quote will be different.
