Nanocrystalline strip for wireless charging of mobile

online order

 * Our company began to produce nanocrystalline and amorphous strips in 1995. It is the first private enterprise to produce nanocrystalline and amorphous strips in China.

* In 1998, our low loss nanocrystalline iron core was applied to the self-excited transformer of a fighter plane.
* Our transformer core was applied to national key projects such as Bird‘s Nest and the Three Gorges Project.
* Our automatic production line of nanocrystalline thin strip for wireless charging is independently designed and manufactured. Siemens automation technology is adopted and high-quality beryllium copper rollers are imported. In 2020, 11 patents were newly declared.
* The nanocrystalline strips produced for wireless charging has the advantages of high density, no pitting and high toughness.
