【本刊讯】日刊《水曜会志》五月三十日刊载题为《铝工业现状与技术研究动向》的文章.现将《铝合金材料的进步》一节摘要如下:成形加工用合金近年来为节省能源,要求汽车节减燃料,其措施是研究使汽车轻量化,因此铝制车身板的应用也与高强度钢和树脂一起成为研究的课题.在美国,车盖、车门等很多部件已经使用铝合金,而且在强度上达到了与冷轧钢板同等的水平,但冲压成形性和点焊接性较差,是目前需要进一步改进的重要课题.在所研究的合金中,30-30合金(抗拉强度30公斤/厘米~2以上、伸长率30%)具有最良好的成形性而受到好评 [Journal] Journal “Water Yao” will be published on May 30 entitled “Current status and technology of aluminum industry,” the article will now “progress of aluminum alloy,” a summary of the following: Forming alloy with the recent years In order to save energy and require cars to reduce fuel consumption, the measure is to study how to make cars lighter, so the application of aluminum body panels is also a research topic together with high-strength steel and resin.In the United States, many components such as vehicle hoods and doors The use of aluminum alloy, but also in the strength reached the same level with the cold-rolled steel, but the poor press formability and spot weldability is currently an important issue to be further improved in the study of the alloy, 30-30 alloy ( Tensile strength of 30 kg / cm ~ 2 or more, elongation of 30%) has the best formability and has been well received
