镁是发展中的第三金属,是21世纪的绿色工程材料;镁的密度是铝的三分之二,钢的四分之一。镁合金作为一种轻量级材料正越来越多的应用在汽车等交通运输工具的生产制造业上。随着节能减排不断升级,汽车轻量化已成为热点,金属镁在汽车领域的应用迎来了新的机遇。汽车减排需求加速汽车所用燃料60%消耗于汽车自重。汽车质量每降低100公斤,每百公里油耗可减少0.7升,二氧化碳排放减少5~10克/公里,汽车自重每降低10%,燃油效率提高6%~8%。因此,汽
Magnesium is the third metal of development, a green engineering material in the 21st century; the density of magnesium is two-thirds of that of aluminum and a quarter of steel. Magnesium alloy is increasingly used as a lightweight material in the manufacturing of vehicles and other transportation tools. With the continuous upgrading of energy conservation and emission reduction, the automobile lightweight has become a hot spot. The application of metallic magnesium in the automotive field ushers in new opportunities. Accelerate the demand for car emission reduction 60% of the fuel used by cars consumed in the car weight. For every 100 kilograms reduction in car quality, fuel consumption per hundred kilometers can be reduced by 0.7 liters, carbon dioxide emissions reduced by 5 to 10 grams / kilometer, car every 10% reduction in weight, fuel efficiency increased by 6% to 8%. So, steam
