Abstract:

Magnesium is one of ten important non-ferrous metals, which recently has been extensively used in the manufactureof automobiles as a substitute of aluminum and steel. Mg alloy can decrease the weight of vehicles, and so to decrease the energy consumption. China produces lots of Mg metals, but with less application. This paper suggests to decrease the Mg production, to save dolomite resources, and to increase the application of Mg in vehicles.

Key words: Mg; study and application; energy saving; new energy

摘要：

镁是10种重要有色金属之一, 近几年开始替代铝材和钢材广泛应用于汽车制造业。 镁合金压铸件在汽车上的应用可以减轻汽车重量,降低能源消耗。我国的原镁产量虽多，但应用不足，建议我国减少镁的初级产品产量，降低炼镁白云岩资源消耗，提高镁在汽车上的应用水平。
