AMG was incorporated in the Netherlands in November 2006, formed as a portfolio from a combination of specialty metals businesses.  The company is organized into three divisions: AMG Critical Minerals, AMG Critical Materials Technologies, and AMG Clean Energy Materials.

AMG Clean Energy Materials

In the late 1970s, Metallurg expanded its operations to Brazil through the acquisition of Companhia Industrial Fluminense (CIF), a producer of specialty chemicals.  AMG’s tantalum mine in Brazil was originally part of the CIF acquisition. AMG Clean Energy Materials spans the vanadium, lithium, and tantalum value chains, and in lithium, AMG will move further downstream into lithium hydroxide production.

AMG Critical Minerals

The AMG Critical Minerals division traces its origins to the development and production of specialty metals to 1870. The predecessor company Graphit Kropfmühl (GK) was formed in 1870 in order to mine graphite in Germany. GK acquired RW Silicium, a producer of silicon metal in Germany, which was formed in 1947. AMG acquired a 60% equity interest in GK in 2008 and completed a full takeover in 2012. Société Industrielle et Chimique de l’Aisne (SICA), the predecessor company to Sudamin Holding S.A. (Sudamin), entered the antimony trioxide business in 1933 and has been operating at the same facility in Chauny, France, since then. In 2001, Sudamin acquired PCDL Lucette, a competing French antimony trioxide producer, and significantly expanded its antimony trioxide presence and market capacity with the acquisition of another French producer.

AMG Critical Materials Technologies

The AMG Critical Materials Technologies division traces its origins to the predecessor companies of ALD Vacuum Technologies GmbH (ALD), founded in Germany during the mid-1800s, and GfE Gesellschaft für Elektrometallurgie mbH (GfE), founded in 1911 as a producer of vanadium alloys and chemicals in Nürnberg, Germany. In the 1940’s, various German industrial companies combined their products and process expertise in the field of vacuum furnace metallurgy to form the immediate predecessor to ALD. In 1994, Leybold-Durferrit, the parent organization of these combined entities, spun out its vacuum furnace division, ALD, as a stand-alone entity. Since then, ALD has achieved global leadership in many vacuum furnace applications including crystallization and turbine blade coating. Additionally, ALD established its “Own & Operate” service model and now has facilities in North America and Europe. In 2016, ALD acquired the remaining 50% share of its joint venture company, ALD-Holcroft Co. Inc., from AFC-Holcroft LLC. ALD-Holcroft, formed in 2005, acts as the exclusive sales agent for ALD’s heat treatment product lines in the NAFTA region. In 1937, GfE expanded its products and operations by establishing a United Kingdom subsidiary, London & Scandinavian Metallurgical Company, Ltd (LSM), a producer of superalloys. In the 1940s, GfE reincorporated in the United States under the name Metallurg, Inc.
