The SF6 Emission Reduction Partnership for the Magnesium Industry was a cooperative effort between EPA and the U.S. magnesium industry to better understand and reduce emissions of sulfur hexafluoride (SF6), a potent greenhouse gas, from magnesium production and casting processes (casting processes involve molding metals). EPA’s voluntary Partnership with the magnesium industry was designed to facilitate progress towards eliminating SF6 emissions by identifying, evaluating, and implementing cost-effective climate protection strategies and technologies including alternative cover gases. Cover gases are used to protect molten metal from oxidation and potentially violent burning during production, casting, and recycling. Studies conducted under the Partnership contributed to the identification of technically proven alternative cover gas options for eliminating the use of SF6.
