The 857 Nuclear factory was founded in the early 1960 's, the company’s location is personally selected in a mountain by China First Prime Minister Zhou Enlai , it was the TOP1 ultrafine nickel powder manufacture factory in Asia, and unique uranium separation membrane factory in China. It gathered a lot of technology experts &talents from the following five colleges: Tsinghua University, University of Science Technology Beijing, Chongqing University, Dalian Institute of Iron and Steel, Central& South Institute of Mining and Metallurgy. And about 750 outstanding officers and soldiers from the PLA of Armed Force, and 1050 young workers from Beijing, Shanghai, Chongqing, Sichuan, total Joined in the old state-owned nuclear group of 857 factory. In 1966, 857 factory finally provided critical core components for the part of atomic centrifuge, make outstanding contributions for China Nuclear Bomb & Hydrogen Bomb industry. Reformed in 2003, in according with the relevant national documents ,had established Chengdu Nuclear 857 New Materials Co.,Ltd.
857 manufactures series of powder metallurgical industry ,including Carbonyl nickel powder, iron powder, ultrafine cobalt powder, chromium, and alloys powder,etc. which owns excellent quality and stable quality. For years, we have been providing to the industries of nuclear, weapons, aerospace, large domestic tungsten carbide, powder metallurgy, and many other industries and many private enterprises with a high quality service.Moreover , we continual progressing our own advantages of the industry, offering the imported matching raw materials to the purchasing department, so that we can meet multi-level customer needs. We are in line with the principle of mutual development and look forward to cooperation with your enterprise.
