Jinconn Magnet Brief introduction

Neodymium magnet grades

Choosing the right neodymium magnet grade is key to unlocking optimal performance in your products. Each grade represents a unique combination of magnetic properties—including residual induction (Br), intrinsic coercivity (Hcj), maximum energy product (BHmax), and maximum operating temperature. These performance indicators play a critical role in ensuring stability, reliability, and efficiency across real-world applications.

At JinConn New Material, we offer a full spectrum of grades from N35 to N56, including high-temperature options such as M, H, SH, UH, and EH. Our materials are trusted in demanding industries including new energy vehicles, industrial robotics, medical technology, smart manufacturing, and high-efficiency motors—where performance cannot be compromised.

We go beyond supplying magnets—we deliver magnetic solutions. Backed by our own R&D platform, advanced magnetic circuit simulation technologies, and over 20 years of industry expertise, JinConn  provides tailored magnetic circuit design and grade recommendation services for customers worldwide.

Whether you're aiming for higher magnetic flux density, better thermal stability, or maximum magnetic output in compact spaces, our engineering team is here to support you—with solutions that align perfectly with your product’s performance goals, structural requirements, and cost targets.
