Ceramic Foam Filter Sverdlovsk Aluminium is embodied in the alloying, purification and refinement processing technology of the smelting process. Ceramic Foam Filters Sverdlovsk Aluminium filters and removes impurities, which can significantly improve the quality of ingots and reduce the scrap rate. It is an important means of purification in the aluminum alloy smelting process. Another problem is that UC RUSAL recently acquired Aluminium Rheinfelden GmbH in Germany. The company’s acquisition has raised widespread concerns that the German company’s advanced manufacturing and design technologies can be used to implement Russia’s armaments program, especially the potential upgrade of its tank fleet. Rheinfelden Aluminum Co., Ltd. was established in 1898 when aluminum production was started near the first river hydroelectric power plant in Europe in Rheinfelden am Rhein. In 2019, Aluminium Rheinfelden GmbH’s revenue reached 159 million euros (US$190 million) (Royal Bank of Canada, February 11). But its sales last year were severely affected by the global business slowdown caused by the COVID-19 pandemic, forcing the company to declare bankruptcy in September 2020 (, February 16). The sale of the aluminum smelter was organized by the bankruptcy administrator appointed by the court. The winning bid was submitted by Russia’s UC RUSAL. According to reports, the entire company’s price is approximately 13 million euros (15.5 million U.S. dollars). The company has 250 employees and an estimated annual turnover of approximately 110 million euros (131 million U.S. dollars) (Frankfurter Allegemeine). Zeitung, April 8). UC RUSAL’s bid won a counteroffer from EuroAtlantic Group and was supported by the daughter of the former German company owner (Südkurier, April 9). According to Germany’s “Foreign Trade Law”, the sale of an advanced industrial company with “dual-use” commercial/military technology requires the approval of the Federal Cartel Office and the German Federal Ministry of Economic Affairs and Energy. , April 18). However, despite the government’s approval of the transaction, questions continue to arise about whether it is wise to allow the sale. For example, Ralf Fücks, a former Green Party politician and head of the Liberal Modernism Think Tank Center, expressed concern that German metallurgical expertise may be transferred to military purposes: a group company that supplies Russian armaments industry” (“Frankfurt Report, March 29). Although the German government has made plain guarantees, the fact that high-quality Rheinfelden aluminum has potential military applications continues to arouse relevant comments (Stuttgart Gazette, March 19).
