The Lightest Metal Waited Eighty Years: Sichuan Laiweimet and the Industrial Inflection Point of High-Strength Wrought Magnesium Alloys
From Pidgeon's process in 1941 to China's rare earth export controls in 2025, magnesium alloy — the lightest engineering metal — has never become a mainstream structural lightweight material. Sichuan Laiweimet uses solidification-strengthening plus continuous production to produce B91C2, a high-strength wrought magnesium alloy with yield strength 340–400 MPa, free of heavy rare earth dependency and SF₆, pushing the global high-strength wrought magnesium alloy landscape to a new tipping point.
