Anneng prapainted Mg-Ti alloy sheet coil is developed and manufactured on the basis of six major durable metals: magnesium, titanium, copper,chromium, zinc and aluminum. We create a new alloy material by using four-step strengthening technology (metallurgical melting, hot rolled annealing,physical cold rolling and recrystallization of alloy atoms), and verify various metallographic parameters, finally achieve mass production and launch in the market, which is mostly used for high-end steel structure roofing and exterior wall decoration.
