I ordered a magnet with N38 performance. How do I know if it is really N38? Or use N35 to shoddy it? I believe that many of my friends are confused about this. Today I will share with you how to distinguish the performance of magnets and see if the ones you bought are really correct.

NdFeB strong magnetic magnets are generally divided into N35/N38/N40/N42/N45/N48/N50/N52 and other grades. The most obvious difference between each performance grade is the difference in magnetic properties. For example, products of the same specification, The higher the performance grade, the better the magnetic performance of the product. However, the neodymium iron boron strong magnet is a kind of surface molecule and its active product, so the surface of the neodymium iron boron strong magnet must be electroplated, such as zinc plating, nickel plating, nickel plating copper nickel, epoxy resin, etc. Wait.

Under normal circumstances, we don't have equipment to test the magnetic properties of products at any time around us, so how do we judge the product performance of a neodymium iron boron magnet? To be precise, there is no way to judge the performance of a magnet product without any testing equipment.

Because they all look the same, you can’t tell what the results are. Maybe you’re looking for a few magnet suppliers, some quoted 0.08, some quoted 0.03, which creates a problem, why is that so cheap, isn’t it? Is it really the grade I want?

In the actual work requirements, we often encounter the need to judge the magnetic properties of the product. If there is a Gauss meter, we can make a rough judgment based on the surface magnetic field of the product. Without the instrument, we need to use the unique product itself. To judge by magnetic conditions, for example, we first use a magnet to attract or repel each other, so we can judge the magnetic poles of the magnet product, at least the magnetic poles in a uniform direction. Magnet, you can feel the magnetic strength of the magnet product by the feel of the hand.

What does N52 magnet mean?

N52 grade neodymium iron boron powerful magnet has high magnetic energy product performance. N52 is a performance grade and is considered to be the strongest performance grade of NdFeB. According to the temperature coefficient, it is divided into n grades, m grades, h grades, sh grades, etc., N52 The 5*5 surface Gauss is larger than the N42 5*5 surface Gauss.

Where is the manufacturer that produces N52 magnets?

N52 magnets are strong in magnetic force, and the price is not cheap, so there are not many customers using this brand. Basically, between N35-N48, some special-shaped NdFeB magnets often use N52 performance.

N52 strong magnetic

Normally, the N35 neodymium iron boron strong magnet material blank is F64*54*35. Normally, the magnetization direction of the neodymium iron boron strong magnet material will not exceed the length and width of the material blank, because if the material is magnetized Once the direction is higher than the length and width of the material blank, the magnetization orientation of the magnetic molecules cannot be agreed, that is, the phenomenon that the magnet cannot be magnetized will occur. Therefore, the high-performance N52 neodymium iron boron strong magnet material is being produced The technical difficulty in the process and sintering process is more difficult than the production of N35 materials.

Guess you pay attention to N52 magnet parameters

N52 magnet: remanence: 1.44-1.48 (T)

Coercivity: 828-907KA/m

Maximum magnetic energy product: 49.5-52

The working temperature of N52 magnet is lower than 70¡æ

The specific difference between n52 magnet and N35 magnet

The two are magnets of different models. Under the premise of the same specification, the magnetic attraction of N52 is much larger than that of N35.
