Samarium cobalt magnet is also called samarium cobalt permanent magnets, rare earth cobalt permanent magnets, etc. It is a magnetic material made of samarium, cobalt and other metal rare earth materials through proportioning, smelting into alloys, milling, pressing and sintering. With high magnetic energy product, extremely low temperature coefficient, the maximum working temperature can reach 350 ºC, and the negative temperature is not limited. When the working temperature is above 180 ºC, its maximum magnetic energy product and temperature stability and chemical stability are all better than NdFeB permanent magnet materials. It has strong corrosion resistance and oxidation resistance, so it is widely used in aerospace, defense and military industry, microwave devices, communications, medical equipment, instruments, meters, various magnetic transmission devices, sensors, magnetic processors, motors, magnetic cranes and other fields.

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.
