On May 25, 2017, Beijing Xinwei Technology Co., Ltd. announced that it intends to acquire British aviation component manufacturer Doncasters for 1 billion pounds, with 100% control. However, because Doncasters' defense division involved components used in US missile and launch systems, the US government blocked the deal on the grounds of national security concerns.
Doncasters is an international leading manufacturer of high-precision special alloy components. Its products can be used under severe conditions such as high temperature and pressure and strong corrosion. The products are widely used in the aerospace, industrial gas turbine, automotive and petrochemical markets, and are at the leading level in the fields of precision casting, forging, machining, high-temperature alloy production, and automotive stud welding equipment supply and manufacturing.
