Taiyo Nippon Sanso Corporation (TNSC), a Japanese industrial gas business company in the Nippon Sanso Holdings Group, has cooperated with Tsukuba Diecasting Co., Ltd. to reduce CO2 emissions equivalent to more than 100,000 tons per year. For this initiative, Tsukuba Diecasting received the 2024 International Magnesium Association (IMA) Award of Excellence in the environment category.
MG Shield is a fireproof cover gas developed by TNSC to prevent oxidation and combustion of molten magnesium alloys. Compared to SF6, a conventional cover gas for molten magnesium alloys, MG Shield significantly reduces CO2 emissions per cylinder by a factor of approximately 22,800.
Tsukuba Diecasting has reduced its annual SF6 consumption by 4,500 kg by replacing the conventional cover gas with MG Shield in FY2023, based on its production technology cultivated through years of magnesium production and technical cooperation from TNSC regarding MG Shield. This equates to reducing over 100,000 tons of CO2 (22,800 in Global Warming Potential).to be finished in 2027.
