金属镁及其合金产品,由于具有一系列优越性能,加上近年来生产成本大幅度降低,其应用领域不断扩大,需求量急剧上升.镁占地壳中元素含量的2.3％,排第6位,大量存在于白云石、菱镁矿、光卤石、盐湖和海水中,可谓取之不尽、用之不竭.而常用金属材料矿产资源趋于枯竭:铜、铝、锌只可开采几十年,铁、铝还可开采100～300年.因此,专家预测,镁将继铁、铝之后,成为第三大实用金属材料.因其可回收利用,又被称为“绿色工程材料”,“21世纪朝阳产业”.
Magnesium and its alloy products, due to a series of superior properties, coupled with a substantial reduction in production costs in recent years, its applications continue to expand, the demand for a sharp rise in magnesium content of 2.3% of the earth’s crust elements, ranked No. 6, A large number of existing in dolomite, magnesite, carnallite, salt lake and sea water, can be described as inexhaustible, and the common mineral resources of metal materials tends to be depleted: copper, aluminum, zinc can only dozens of mining Therefore, experts predict that magnesium will become the third largest practical metal material after iron and aluminum because of its recyclability, which is also called “green engineering material” “21st Century Sunrise Industry”.
