| 摘要 |
A new alloy of aluminum is disclosed which consists essentially of residual silicon up to 0.60 percent, residual iron up to 0.70 percent, residual zinc up to 0.30 percent, 0.05 to 0.20 percent copper, 0.40 to 0.90 percent manganese, and balance essentially aluminum. The properties of the alloy are especially conducive to producing sheet metal stock cast by continuous methods and have a general wide-ranging utility for forming many products, heretofore unobtainable from a continuous casting method.
