Ningbo Yunsheng Co. Ltd., is located in Ningbo prefecture, the “Silicon Valley of Magnetics” in China, home to 100+ magnet manufacturers.
In 2013, Yunsheng renewed its license agreement with Hitachi Special Metals, and remains among an elite group of approved patent licensees. We are, therefore, able to guarantee that every Yunsheng product is manufactured from our own facilities using licensed materials and certified processes only. Yunsheng also holds the sublicense to sell NdFeB magnets under Magnequench patents.
DY-FREE AND LOW-HRE
dependence on HRE (Heavy Rare Earth) material used to control coercivity. Yunsheng has made enormous strides since 2012 to completely eliminate Dysprosium and Terbium from almost half our material grades. Today, Yunsheng already provides Dy-free grades up to 48H with significant HRE reductions (up to 70%) in our low-HRE grades. As Yunsheng anticipates the growing demand in Neodymium magnets from the automotive and industrial sectors for higher efficiency and cost-down opportunities, our R&D team continues to develop and expand its sustainable practices programme for HRE-free grades.
Since 2011, as part of a national mandate from the Chinese Government 863 Project, Yunsheng researched the development of low HRE material grades.
The 863 project finished in 2014.
Yunsheng has continued its own low HRE grade development programme.
1.Yunsheng continues to extend its Dy-free programme to more material grades, in line with its Dy elimination programme.
2.Yunsheng continues its development of proprietary low HRE material grade technologies to eliminate the use of Ho and other Dy substitutes used in Dy-free grades.
3.The continued reduction or elimination (where possible) of all HRE in its material grades remains a key priority and objective for Yunsheng.
