我国金属时资源集中于青海、西藏、甘肃、内蒙等地的盐湖中,其中青海湖蓄藏最多。锂是金属中最轻的元素,密度为534kg/m~3,呈银白色。锂是既轻又软的特殊金属,具有3大特性。 金属味精 某种金属中加入一点锂就能改变此金属性质。例如铝—锂合金,是最轻的铝合金。铝的密度就很低,为2700kg/m~3,而锂的密度就更低了。如铝中含有1％～3％Li,合金密度就比普通铝合金密度小12％～17％,刚度提高5％～20％,
China’s metal resources concentrated in Qinghai, Tibet, Gansu, Inner Mongolia and other places in the Salt Lake, Qinghai Lake, where the most storage. Lithium is the lightest element in the metal, with a density of 534 kg / m ~ 3, silver-white. Lithium is a light and soft special metal with 3 major features. Metallic MSG Some metal added a little lithium can change this metal properties. For example, aluminum - lithium alloy, is the lightest aluminum alloy. The density of aluminum is very low, 2700kg / m ~ 3, while the density of lithium is even lower. If the aluminum contains 1% ~ 3% Li, the density of the alloy is 12% ~ 17% less than that of the ordinary aluminum alloy, the rigidity is increased by 5% ~ 20%
