Aluminum alloys having improved mechanical properties and workability and method of making same |
摘要 |
An aluminum alloy consisting essentially of 8 to 15% by weight of silicon, 0.05 to 0.7% by weight of magnesium, 1 to 4.5% by weight of copper, the balance being aluminum, wherein a silicon crystal in eutectic structure crystallized out in an aluminum matrix has a mean grain size not larger than 5 microns and intermetallic compounds of magnesium and copper are finely precipitated in the matrix as age-hardening elements for the matrix, and the alloy has at least 40 kg/mm2 tensile strength and at least 10% elongation, good antiwearing and excellent workability.
