Advantage High performance, low termpeature coefficient with high working temperature 350 degree centigrade. When working over 180 degree centigrade, the maximum energy BH and steady temperature are superior than NdFeB magnet. it is not easy to corrode and oxidize as Neodymium magnets,  so ineed not  to be coated, demagnetization rate of <3%.
Features: no matter how bad the environment,its performance of magnetic is still strong!
Characteristic Smco ‘s high magnetic force and working temperature : Compared to traditional motor, rare-earth magnet coreless motor with high efficiency, light weight, small size, good speed control,reliability, etc., can be widely used in wind power, electric vehicles,industrial motors, and other fields. In the low-carbon energy saving background, samarium cobalt market is very large. Currently in Japan
and Europe and other countries use about 98% of the air-conditioning inverter air conditioner, but China seldom use. inverter air conditioner has a comfortable, energy-saving features, will become a trend in the future.

Why Choose Us

Harwell magnet factory Why Choose Us 6




Q1: Can I have a sample order for Neodymium magnet?
A: Yes, we welcome sample order to test and check quality. Low MOQ of 1pc for sample checking is available.Mixed samples are acceptable. Please cover the freight.

Q2: What about the lead time?
A:Sample needs 3-5 days, mass production time needs 15~30 days for each order in general.

Q3: How do you ship the goods and how long does it take to arrive?
A: We usually ship by DHL, UPS, FedEx or TNT. It would take around 3-5 days to arrive. Airline and sea shipping are also available.

Q4: Is it OK to print my logo on magnet product or package?
A: Yes. Please inform us formally before the production and confirm the design firstly based on our sample.

Q5: How are Neodymium Magnets made?
A: The main ingredients are Neodymium, Iron and Boron. The exact ingredients depend on the grade being produced. We also add a key ingredient called dysprosium to raise the coercivity of the material and increase the resistance to demagnetisation and corrosion. You can read more about the manufacturing process in our company website,

Q6: How do you make our business long-term and good relationship?
A: We keep good quality and competitive price to ensure our customers’ benefits. We respect every customer as our friend and we sincerely do business and make friends with them, no matter where they come from.
