China Neodymium And Ferrite Magnets Manufacturer & Supplier 
N35 is neodymium magnets in a variety of grades in the application of more than one, mainly because of cost-effective, magnetic to meet the application, in the purchase of N35 magnets, but also encountered a lot of customer problems, the following collated some of the more frequent problems.
1. How strong is the magnetic force of N35 magnet?
This mainly depends on the size of the magnet, the bigger and thicker, the stronger the magnetism will be, such as a diameter of 10mm, 2mm high N35 magnet for example, its surface magnetic field strength up to 2000 gauss or so, the vertical pull of about 0.66kg.

2. What are the main parameter data for N35 magnets?
Remanent magnetization BR approx. 1.17-1.22 T, coercivity ≥ 868 kA/m, max. magnetic energy product 35 MGOe, operating temperature ≤ 80°C.
3. What is the difference between N35 and other grades (e.g. N52, N54)?
N35 has a lower magnetic energy product (35MGOe) than N52 (52MGOe), N54 (52MGOe), and is weaker but less costly.
4. Can N35 magnets stick to stainless steel?
It depends on the material of the stainless steel. 304 and 316 stainless steel have a high nickel content and are highly anti-magnetic, making it difficult for magnets to adhere to them. 430 stainless steel has a high iron content and can be adsorbed by magnets. To fix N35 magnets, they can be glued (e.g. epoxy resin glue, 502 glue) or mechanically fixed.
5. Are N35 magnets prone to rust? How to prevent rust?
As long as the neodymium material is easy to rust, N35 is no exception, the surface usually need to be coated to protect (nickel, zinc, epoxy resin, etc.). In addition, avoiding humid environment or plastic wrapping N35 magnets can better prevent rust.
6. Can N35 magnets be machined to any shape or size?
Although N35 NdFeB magnets can be processed to realize a variety of shapes and sizes, they can not be processed completely “arbitrarily”, for example, some ultra-complex shapes and ultra-thin (0.1mm) sizes may not be processed.
7. How long is the service life of N35 magnets?
Under the condition of no physical damage, corrosion and high temperature demagnetization, the magnetism can generally be maintained for more than 10 years.
8. Can I drill or cut into N35 magnets?
I don't don't recommend it. The NdFeB material is highly brittle and prone to breakage or demagnetization with machining.
9. How do N35 magnets compare to other materials (e.g. ferrite, alnico)?
The magnetic force is much stronger than ferrite, and the cost performance is higher than Alnico. Corrosion resistance is worse than ferrite, and high temperature resistance is not as good as Alnico.
10. What is the price of N35 magnets?
The price of N35 magnets is affected by size, plating, temperature resistance, processing difficulty, order quantity, etc. Larger sizes or special shapes are more expensive. The price is higher for large size or special shape magnets. If there are special requirements for temperature resistance and coating, the price will be increased.
