随着汽油价格不断上涨,铝、镁与钛等轻质材料在汽车上的应用也不断增加。钛的优点是比强度高,耐蚀性好。轻质钛零部件可降低汽车重量,因而降低了燃料消耗。钛的主要缺点是比其他轻金属价格高。但随着提取技术的改进以及采用粉末冶金等先进工艺,制造成本已大为降低。以德国大众 As gasoline prices continue to rise, aluminum, magnesium and titanium and other lightweight materials in the automotive applications are also increasing. Titanium has the advantage of high strength and good corrosion resistance. Light weight titanium parts reduce the weight of a car, thus reducing fuel consumption. The main disadvantage of titanium is the higher price than other light metals. However, with the extraction technology improvements and the use of advanced technologies such as powder metallurgy, manufacturing costs have been greatly reduced. To the German public
