1. Material
Rare earth Powder, Cost-effective The raw materials are neodymium, iron and boron. Starting from material selection, high quality ndfeb strong magnetic materials are manufactured with high quality rare earth neodymium materials and various mixed materials.


2. Size Tolerance

+/-0.05mm
a. Before grinding and cutting, we inspection the black product tolerance.
b. Before and after coating, we will inspection the tolerance by AQL standard.
c. Before delivery, will inspection the tolerance by AQL standard.
3. Customized Magnets
Strong Neodymium Arc magnets are used in building motors, generators or magnetic bearing. Since neodymium magnets N35,N36,N42,N45,N50 & N52 are much stronger than other magnets, using strong neodymium magnets can build much more powerful motors, generators.

How Strong is Neodymium Magnet?
-- Different NdFeB Magnet Parameters:
Magnet Application:
Used in electronic, electrical machinery, medical equipment toys packaging, metal machinery, aerospace and other fields, The more common permanent magnet motor, speaker, magnetic separator, computer disk drive, household appliances, digital cameras, mobile phones, stationery, handicrafts, magnetic resonance imaging equipment etc.
Qaulity Control
How Neodymium Magnet is Made ?
-- Production Process:

Product Package:


1. Magnet is a special goods for delivery, and they have to make special packing before transportation.
2. Antimagnetic Packaging / Neutral Packing / Custom-make Welcome.

Magnet is a brittle product, with strong magnetic force. Improper handling and shaking may cause damage during transportation, so professional package is very important.
Jin Tong adopts the strictest package, and our products could be shockproof and waterproof, besides satisfy magnetic isolation requirement. Our package is totally suitable for sea and air transportation, which makes our products could pass customs inspection fluently.

FAQ
Q1: What is a neodymium magnet?
A: 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?
A: 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.

Q3:Are you a factory or trade company?
A: We are specific in produce of neodymium magnet over 24 years and now has 2 factories in China.

Q4: Could i visit your factory, where is your factory?
A: Welcome,Our main factory located at Changzhi city, Shanxi province, The other branch plant locate at Guangdong province.

Q5: Can you supply custom magnets service?
A: Yeah, we can customized any sizes of magnet based on your demand.

Q6: What is your sample policy?
A:If the round magnet diameter below 30*3mm are available, we could provide 20-30 pcs samples for free to you, you just need to pay the delivery fee.

Q7: What is your terms of payment?
A: Alibaba Trade Assurance / T/T / Paypal. 100% in advance.(less than 5000$,100%payment, more than 5000$, 40% deposit, 60%balance)
