一、钛金属简介钛是过渡元素,化学性质活泼。由于提炼困难,过去一直被列为稀有金属。其实地壳中钛的含量是锰的7倍,铜的60倍,铅的400倍,仅低于铝、铁、镁而居第四位。本世纪五十年代,由于航空、航天工业的迫切需要及钛提炼技术的发展,钛获得了工业应用。目前,钛及其合金在冶金、化工、石油、轻纺、造船等民用工业中也获得越来越广泛的应用。纯钛是一种灰色的金属,熔点1668℃,
First, the introduction of titanium Titanium is a transitional element, the chemical nature of lively. Due to refining difficulties, the past has been classified as rare metals. In fact, the content of titanium in the crust is seven times that of manganese, 60 times that of copper and 400 times that of lead, ranking only the fourth place among aluminum, iron and magnesium. Fifties of this century, due to the urgent needs of the aviation and aerospace industries and the development of titanium refining technology, titanium has been industrial applications. At present, titanium and its alloys in the metallurgical, chemical, petroleum, textile, shipbuilding and other civilian industries have also been more widely used. Pure titanium is a gray metal, the melting point of 1668 ℃,
