Advanced Technology & Malerials Co., Ltd (AT&M), a national high-tech enterprise, focuses its business on R&D and 

manufacture of new metallic materials and products. Located in the Zhongguancun Science Park in Beijing, AT&M was established 

by China Iron & Steel Research Inslitute Group (CISRI), a large state-owned scientific research institute, in Dec. 1998 and 

underwent a successful lPO on the Shenzhen Stock Exchange in May 2000. By the end of Nov. 2011, the registered capital has 

reached 854.87 Million RMB. 

The mission of AT&M is to be the foremost manufacturer of metallic materials and products in the world. In the past ten years, AT&M 

has provided its customers with the solutions to their materials technology problems in the main six industry fields of advanced 

energy materials including solar energy and amorphousfnano-crysLaliine materials, powder metallurgy products, metallic magnetic 

materials, welding materials, diamond tools and high speed tool steels. AT&M has made great contributions to the R&D of key 

matenals for many crucial industries such as aerospace and astronautics, information technology, metallurgy, advanced energy and 

environmental protection, etc. 

By ten-year development, AT&M has already established four production sites in Yongfeng, Konggang, and Changping areas of 

Beijing, and Zhuozhou in Hebei province. It also wholly owns or holds shares in 11 companies in Shanghai, Shijiazhuang, 

Shenzhen, and Beijing. Internationally, AT&M has made great efforts to promote global trade and has established sales channels as 

well as technical cooperation relationships in North America, Europe and Asia. Also, AT&M established its subsidiaries in Japan and 

Viet Nam. Its products have been exported to more than 50 countries and regions and have been accepted by many well-known 

domestic as well as international enterprises. 

Based on the Larget of ~creativity, brand and profit orientation-, AT&M has constructed an advanced technology innovation platform, 

The company boasts a research and development group directed by academicians of the Chinese Academy of Engineering with 

more than 40 Ph Os as the core strength. AT&M is one of the first 118 state-approved enterprise tech nology centers and affiliated 

with three state engineering research centers and laboratories and a post-doctora l research station. 

As the Chinese economy expands rapidly, AT&M will constantly evolve to utilize its strengths in new material manufacturing 

techniques and engineering expertise to meet the requirements of the developing marke\. AT&M aims to provide high performance 

_ \ materials and products of the highest quality for industrial partners all over the world. With its excellent technological expertise and 

~~~ [)./'4A.. solutions, it will promote the development of high-tech areas such as Lhe in formation, environmental protection, bioengineering, 

V"f'UlI~ \O()JV\ "'" electric and electronic industries and build a large sca le cross-industry. cross-area and transnational enterprise.
