1. Materiale
are manufactured with high quality rare earth neodymium materials and other various materials mixed together uniformly.
un. Before grinding and cutting, we inspect the black product tolerance.
b. Before and after coating, we will inspect the tolerance by AQL standard.
c. Before delivery, we will inspect the tolerance by AQL standard.
PS: Product size can be customized.
3. Trattamento della superficie
sì. If magnets are without surface coating (also named plating), it may rust easily under humid conditions.
There have many plating options like Nickel, Zinco, Oro, Black Epoxy, White Epoxy coating and so on.
Zn and Nickle coating are the most popular coating. The magnet with plating will resist the corrosion effectively.
Different coatings for your choose
Rivestimento | Suface Color | Coating Thickness | Applicazione | Salt Spray Test |
Zn | Blue White | 5 ~ 10 Microns | Have a high anti-corrosion ability | > 24 hr |
Nickle | Glowing Sliver | 15 ~ 30 Microns | Applicable to a more harsh enviroment | > 48 hr |
Epoxy | Nero | 15 ~ 30 Microns | Toy, insulation machinery | > 300 hr |
Oro | Golden | 5 ~ 10 Microns | Decorativo, heathy-care | > 24 hr |
How Strong is Neodymium Magnet?
CANTON FAIR every year, Cina
— In 2013, invested USD30,000,000 to establish new factory as production base with 35000 SQM in Changzhi city.
— Established our branch companies in Shenzhen & Guangzhou & Dongguang province for fast service.
— We could supply full turnkey production line for customers. Our factory is equipped with efficient welding furnace & vacuum rapid condensation furnace etc.

Cover N25 ~ N52 such normal strong grade and M, H, SH, UH, EH, AH high temperature resistance grade magnets.
Now we occupy a considerable market share in Chinese market. Especially for load speakers supplying market.
UN: Neodymium magnet is also named NdFeB magnet, and its chemical formula is Nd2Fe14B. Neodymium magnet is a man-made permanent magnet, and it is a magnet with the strongest magnetism under normal temperature at present.
Q2: What is the difference between sintered neodymium magnet and bonded neodymium magnet?
UN: Neodymium magnet includes sintered neodymium and bonded neodymium magnet. Bonded magnet actually is made through injection moulding technology, and sintered neodymium magnet is made through high temperature heating under vacuum condition. The magnetism of sintered neodymium is much stronger than the magnetism of bonded neodymium magnet.
UN: Neodymium magnets will likely lose less than approximately 1% of their flux density over a 10-year period if their physical properties remain intact, and they are not subjected to demagnetizing influences (such as high-temperatures, opposing magnetic fields, radiation etc.)
Q4: Sei una fabbrica o una società commerciale?
UN: We have engaged in R&D and manufacture neodymium magnet over 25 years and now has 2 factories in China.
Q5: Could i visit your factory, where is your factory?
UN: Ben arrivato. Our main factory is located in Changzhi city, Shanxi province, The other branch plant is located at Guangdong province.
Q6: Can you supply custom magnets service?
UN: Yeah, we can customize any size of magnet based on your demand.
Q7: Quali sono i tuoi termini di pagamento?
UN: Alibaba Trade Assurance / T/T / Paypal / L/C.
D8: How do you control the quality?
1) We monitor magnet production from raw materials to the whole production processes
2) Equip various advanced testing instruments to ensure the quality stability
3) We have QC Department to ensure an ongoing development and maintenance with high quality standards
4) Check the packing before delivery.
