HIGH-STRENGTH ALUMINUM ALLOY THIN EXTRUDED SHAPE AND METHOD FOR PRODUCING THE SAME |
| 摘要 |
An Al—Zn—Mg—Cu-based high-strength aluminum alloy thin extruded shape has a yield strength of 700 MPa or more. The high-strength aluminum alloy thin extruded shape includes 9.0 to 13.0 mass % of Zn, 2.0 to 3.0 mass % of Mg, 1.0 to 2.0 mass % of Cu, and 0.05 to 0.3 mass % of Zr, with the balance being Al and unavoidable impurities, fine precipitates having a circle equivalent diameter of 5 to 20 nm being dispersed in a crystal grain of the extruded shape in a number of 4000 to 6000 per μm2. |
