铝合金不仅重量轻,而且具有优良的综合性能。为了把铝合金广泛用于坦克装甲车辆以減轻重量,便于空运、空投,以适应机械化部队的需要,国外经多年研究,研制出数种具有良好抗弹性能的铝合金。这 Aluminum is not only light weight, but also has excellent overall performance. In order to make the aluminum alloy widely used in tank armored vehicles to reduce the weight and facilitate air transport and airdrop to meet the needs of mechanized units, several aluminum alloys with good anti-ballistic performance have been developed abroad for many years.
