前言铝和铝合金具有重量轻,强度高,防震和容易挤压成材等特点。以铝代钢有着世界范围内的先进性。近十几年来,铝质材料在建筑业方面得到极广泛的应用,民用和建筑上的用量大幅度增长。在国外,如美国、德国、英国、意大利、荷兰、南非、瑞士、日本和东南亚等许多国家,铝型材的应用十分盛行。我国的铝资源丰富,近些年来,开发利用铝材制品速度很快。最近,我省的铝厂及其它一些工厂企业也在铝型材的生产方面,开始起步。随着铝工业的迅速发展,铝型材的深度加工越来越引起人们的重视。但在我省 Preface Aluminum and aluminum alloy are light weight, high strength, shockproof and easy to extrude and so on. With aluminum steel has world-wide advanced. In the past ten years, aluminum materials have been widely used in the construction industry, and the amount used in civil and construction has increased substantially. In foreign countries, such as the United States, Germany, Britain, Italy, the Netherlands, South Africa, Switzerland, Japan and Southeast Asia and many other countries, the application of aluminum is very popular. China has abundant aluminum resources. In recent years, the development and utilization of aluminum products has been very fast. Recently, the aluminum smelters in our province and some other factories and enterprises started to start production of aluminum profiles. With the rapid development of aluminum industry, the deep processing of aluminum profiles has drawn more and more attention. But in our province
