This is the most widely used of all aluminum alloys. It is essentially commercially pure aluminum with the addition of manganese, which increases the strength some 20% over 1100. Thus, it has all the excellent characteristics of 1100 with higher strength. It has excellent corrosion resistance and workability, and it may be deep drawn or spun; welded, or brazed. This alloy is non-heat treatable.
Sheet and Plate: QQ-A-250/2, ASTM B 209, AMS 4006, AMS 4008.
3003 aluminum coil and sheet is approximately 20% stronger than 1100 series aluminum. 3003 aluminum reacts well to mechanical finishings as well as organic finishes. 3003 welding is readily accomplished by means of conventional welding methods, but may be gummy if machined. Soldering is limited to the torch method.
Jianhui Aluminum has a wide range of sizes readily available to the AMS 4006 for O temper, AMS 4008 for H14.
