【Abstract】 A new MaxiFlow 6××× aluminum alloy available with high speed extrusion developed by Rusal is briefly introduced. According to the new concept, the experts adjust the contents of Mg and Si elements in the standard composition range of some of the existing 6××× aluminum alloys, and optimize the homogenization process system of ingot to reduce the harmful effect of impurity Fe, so as to achieve high-speed extrusion performance. This paper introduces some successful cases of high speed trial extrusion in the enterprises of different countries on MaxiFlow 6××× aluminum alloy billets, which brings good economic benefits. It is worth developing by domestic aluminum processing enterprises and related scientific research institutes.更多还原
