Dec 17, 2014· Magnesium burns too easily to be used widely for building, according to the Jefferson Lab, but when mixed with aluminum, it creates an alloy that is strong, light and easy to work with. Magnesium
Sep 19, 2013· Magnesium alloys are utilized in many engineering appliions where having light weight is a significant advantage. Magnesium alloys have always been attractive to designers due to their low density, only two thirds that of aluminum. This has been a major factor in the widespread use of magnesium alloy castings and wrought products [20-22].
