| 摘要 |
The present invention provides a novel aluminum based alloy which provides good resistance to corrosion, good brazeability, good workability or extrudability during fabrication of product, and imparts good mechanical strength to the fabricated articles. The invention provides an aluminum alloy material consisting essentially of, by weight percent, 0.02 % to 0.12 % silicon, 0.07 % to 0.27 % iron, 0.05 % to 0.45 % copper, 0.06 % to 0.26 % manganese, and 0.05 % to 0.25 % titanium, with the balance being aluminum with normal impurities. The present invention also provides an improved process for heat treating and extruding the foregoing aluminum alloy. |
