High-temperature neodymium magnets—grades like H, SH, UH, and EH—are essential for demanding applications in automotive, industrial motors, energy systems, and advanced electronics. While China remains the world’s largest producer of these magnets, exporting high-temperature grades is far more complex than shipping standard neodymium materials. For engineers, buyers, and sourcing teams, understanding this process helps explain...Read More

In 2025, China significantly escalated its control over the global rare earth magnet supply chain by introducing strict export restrictions. These measures have sent shockwaves through industries that rely heavily on advanced magnets, such as electric vehicles (EVs), renewable energy, aerospace, and defense. As the world scrambles to secure alternatives, China’s policies are reshaping the...Read More

Magnet grades describe magnetic material performance—not pull force or surface gauss. Learn what N35, N42, N52 and temperature suffixes such as H, SH, UH and EH mean, how BHmax, Br and HcJ differ, and how engineers should choose the right grade for an application.Read More

Unveiling the Power of SmCo Magnets: A Comprehensive Guide to Their Composition, Properties, and Applications Samarium cobalt (SmCo) magnets, known for their exceptional magnetic properties and high resistance to demagnetization, have been a key player in the world of magnets since their development in the 1970s. These rare-earth magnets, composed of samarium and cobalt along...Read More

Heat-resistant magnets must be selected by material, grade, HcJ, geometry and operating temperature—not temperature rating alone. Compare high-temperature NdFeB grades (M, H, SH, UH, EH and AH), ferrite and Alnico, and see how permeance coefficient, load line and demagnetization margin affect real high-heat performance.Read More

Magnet technology has come a long way since its inception. With the advent of new materials and production techniques, magnets have become more powerful and versatile than ever before. One such type of magnet is the SmCo magnet, which has been gaining popularity in recent years due to its high energy and low cost. In...Read More
