3M Novec 612 Magnesium Protection Fluid SF6 Replacement Ultra Low GWP
Type: Magnesium Cover Gas
Boiling Point: 49.2°C
GWP: 1
Atmospheric Lifetime: 5 days
Packing: Liquid / Custom
3M Novec 612 Magnesium Protection Fluid is a sustainable cover gas agent designed to replace sulfur hexafluoride (SF₆) in magnesium casting operations. With a global warming potential (GWP) of just 1 — equivalent to carbon dioxide — and an atmospheric lifetime of only 5 days, Novec 612 offers a dramatic reduction in greenhouse gas emissions compared to SF₆ (GWP 23,500, lifetime 3,200 years). This clear, colorless, low-odor fluoroketone is a liquid at room temperature, enabling easy transport and handling in conventional containers, and evaporates readily into a gas stream for use as a cover gas due to its high vapor pressure and low heat of vaporization.
Novec 612 provides excellent protection for molten magnesium and its alloys at melt temperatures from 650°C to 800°C in various casting processes, including die casting, ingot casting, sand casting, and investment casting. It forms a thin, flexible surface film that prevents oxidation, with typical use concentrations of only 0.01% to 0.1% — significantly lower than SF₆ (0.1-6.0%) or other agents. Field studies by the U.S. EPA have demonstrated that Novec 612 can reduce greenhouse gas emissions by more than 99% compared to SF₆, while maintaining comparable operating costs. Its low toxicity (exposure guideline 150 ppm, TWA) and nonflammable properties ensure a wide margin of safety for workers. With proper equipment optimization and carrier gas formulations (CO₂ or N₂ with dry air), Novec 612 delivers robust, cost-effective, and sustainable magnesium melt protection.
