ALCOA 1XXX SERIES (Extruded Non-Heat-Treated Aluminum Alloys)

摘要

Comparative characteristics for these alloys to others are shown in Fig. 1 for several tempers. The flatwise minimum bending radius for 1350-H111 is 1 x thickness for all thicknesses and 90 deg bend with width to thickness ratio not exceeding 12 and widths not exceeding 100 mm (4 in.). Alcoa Engineered Products markets several alloys in the Ixxx series for many specialty applications. The alloys are non-heat-treatable, have the highest purity of aluminum compared to other series of aluminum alloys, and are offered as extruded sections with a minimum purity of 99.5 percent aluminum by weight. Some specific alloys offer aluminum contents as high as 99.0 percent aluminum by weight while some go to 99.6 percent. This alloy group offers the best corrosion resistance of any aluminum alloy group and displays excellent forming, welding, brazing, and finishing characteristics. Excellent forming characteristics permit these alloys to be easily impacted, cold drawn, deep drawn, and bent into various configurations. These alloys can be extruded as profiles, rod, and bar. Three of the common alloys available are 1060, 1100, and 1350. Other Ixxx series alloys may be available through special inquiry.
