铝锂合金新材料的高强度、低比重为其特色,可望取代传统合金成为飞机建材。西欧五国合造的空中巴士 A—320型民航客机,预定1988年出厂,波音公司研制中的新客机都准备用铝锂合金作部分非结构性材料。锂(原子量6.9)为最轻的金属元素,在世界上存量甚丰富,但现有的锂矿石为数不多。干粉状氯化锂,是电解法制锂的基本原料。锂的溶点(180.54℃)较低,极易与氧反应,但与铝制成合金并固化后,锂就稳定不会活动。铝锂合金不锈
Al-Li alloy new material of high strength, low specific gravity for its characteristics, is expected to replace the traditional alloy aircraft building materials. Airbus A-320 airliner, a joint venture of Western European and European countries, is scheduled to be delivered in 1988 and new passenger aircraft under development at Boeing are all ready to be partially non-structural materials made of aluminum-lithium alloy. Lithium (6.9 atomic weight) is the lightest metal and is abundant in the world, but few existing lithium ores exist. Dry powder lithium chloride, lithium is the basic raw material for electrolytic law. Lithium has a low melting point (180.54 ° C) and is very reactive with oxygen but alloyed with aluminum and cured, lithium is stable and will not move. Aluminum lithium alloy stainless steel
