Abstract: The application of magnesium alloys as mobile phone shell materials is developed rapidly because of their abundant resources, light weight, high thermal conductivity, good electromagnetic shielding characteristics, and easily recycled properties. The development and pollution tendency of mobile phones, as well as compared and assessed both plastics and magnesium alloys as mobile phone shell materials through sample life cycle matrix are discussed. The result shows that except energy consumption, the magnesium alloys are more superior to plastics in their performance, recycling, and environmental burdens.
