NdFeB Magnets-Permanent Magnets-Jinghong Magnets (JMAG)-Industrial Magnets Manufacturer

Description of NdFeB Magnets

· NdFeB magnets are the strongest permanent magnets commercially available in the world. They can provide unparalleled levels of magnetism and resistance to demagnetization when contrasted with Ferrite, AlNiCo, and SmCo magnets.

· Due to their excellent magnetic properties, NdFeB magnets offer great flexibility of use in replacing traditional materials such as ferrite magnets, alnico, and samarium cobalt with greater efficiency and a more compact format.

· NdFeB magnets can have a maximum energy product of up to 55 MGOe, and they possess a high remanence and coercivity. They are available in a wide range of colors, sizes, and shapes to suit specific applications.

Characters Of NdFeB magnets

· Very high resistance to demagnetization

· High energy for size

· Good in ambient temperature

· Moderately priced

· Material corrodes quickly, and surface treatment is necessary

· The highest working temperature for NdFeB magnets can be 220℃

Q: Are you manufacturer?

A: Yes, we are. Our factory was established in 2003 with more than 6000 square meters.

Q: Do you supply OEM services?

A: Yes, we do. Our professional team will help you to choose the proper material grade for your products.

Q: What’s your lead time?

A: Usually, the lead time for magnets is 30 days. It will be shortened or lengthen depends on the season or customer’s requests.

Q: When can we get your reply?

A: We always reply to you within 24 hours and provide you with an excellent solution.

Q: How can you guarantee your products?

A: Excellent customer service is one of our characteristics. All defective products will be replaced free of charge as early as possible.

Q: How to order magnets?

A: Due to the Neodymium magnet are not a standard mechanical component; basically, all the dimensions will be produced according to the customer’s requirement. Sometimes, we keep the rough semi-finished products (cylinder and block shape) in stock for urgent need.
