Beyond the Core – Redefining Electromagnetic Performance with Leimai Electronics
In the precision electromagnetic components industry, the material often sets the ceiling for device performance. At Shanxi Leimai Electronic Technology Co., Ltd., we start right at the source – dedicated to the R&D and manufacturing of nanocrystalline ribbon and nanocrystalline cores. By controlling the material foundation, we deliver solutions that offer higher performance, smaller footprints, and lower losses for our customers.
From Material to Magnetic Core – Defining the Performance Frontier
We fully understand that the quality of nanocrystalline ribbon directly determines the final performance of the magnetic core. Our iron‑based nanocrystalline ribbon, produced using ultra‑rapid solidification technology, exhibits high permeability and low core loss at high frequencies – making it an ideal replacement for traditional ferrite, silicon steel, and permalloy. Through precision winding, controlled thermal‑magnetic annealing, and impregnation processes, we convert this ribbon into a wide range of nanocrystalline cores. These cores are widely used in key sectors such as new energy vehicles, photovoltaic energy storage, smart grids, and consumer electronics.
Key Advantages Over Conventional Materials
• Superior Performance – Initial permeability exceeds 80,000, with a saturation magnetic flux density of 1.25 T. Our cores maintain excellent frequency response across a broad frequency range.
• Compact and Lightweight – The high saturation flux density enables significant size and weight reduction compared to traditional solutions at the same power rating, facilitating miniaturization of end products.
• Wide-Temperature Stability – Operating temperature ranges from –40 °C to 140 °C, with a Curie temperature of 560 °C, ensuring stable performance even in harsh environments.
Why Choose Leimai?
• End-to-End Quality Control – With full in-house production from ribbon to finished cores, we ensure complete traceability and consistent quality. Our annual production capacity reaches 1,500 tons, supported by advanced production lines and a modern manufacturing base.
