| Abstract: | This article compared and assessed both magnesium alloys and plastics as laptop computer shell materials through life cycle assessment are discussed. The result shows that except energy consumption, greenhouse effect of magnesium alloys is 556.31%, 383.30%.The magnesium alloys are more superior to plastics in their performance, resource consumption, acidification, human toxicity and recycling. |
