Improved Formability and Corrosion Resistance of Pure Magnesium by Parts-Per-Million-Level Addition of Copper and Calcium
Poor cold formabilityFormability, poor corrosion resistance, and high cost of alloying elements are longstanding barriers to the widespread use of magnesium (Mg) andMagnesium alloys (Mg alloys) its alloys. In this study, we demonstrated that both the room temperature (RT) stretch formability and corrosionCorrosion resistance of commercially used pure Mg could be significantly improved by adding trace amounts of copper (Cu) and calcium (Ca). Owing to the addition of trace amounts of the alloying elements, the resultant alloy also showed excellent thermal conductivityThermal conductivity, which is almost two times higher than that of the most commonly used Mg alloy (AZ31) and even higher than that of a commercial Al alloy (A5052). These findings are expected to stimulate the development of high-performance Mg alloysMagnesium alloys (Mg alloys) that can be used in portable electronic devices, automobile electronics, and household appliances.
