Claims
- 1. Aluminum alloy having a shear strength greater than 100 MPa at 300.degree. C. and a formability greater than 0.9 true strain, as measured at room temperature (22.degree. C.) with a strain rate of 8.7 sec.sup.-1.
- 2. Aluminum alloy as claimed in claim 14, consisting essentially of 4 to 12 wt.-% Fe, 2 to 14 wt.-% Ce, remainder substantially Al.
- 3. Aluminum alloy as claimed in claim 2, consisting essentially of about 8.3 wt. % Fe and about 4.0 wt. % Ce, remainder substantially Al.
- 4. Aluminum alloy as claimed in claim 1, in the form of an extrusion, forging, plate, sheet or fastener stock product.
- 5. Aluminum alloy as claimed in claim 1, in the form of rivet stock.
- 6. An high-strain-rate riveted assembly of aluminum alloy components having a shear strength greater than 100 MPa at 300.degree. C. joined by fasteners of aluminum alloy, the fasteners having a shear strength greater than 100 MPa at 300.degree. C., the components being either neutral or else anodic with respect to the fasteners by no more than 20 millivolts as measured in an aerated 1-molar NaCl solution and by no more than 50 millivolts when measured in an aerated 31/2 wt.-% NaCl solution.
- 7. Aluminum alloy containing at least 74 wt.-% aluminum and having a shear strength greater than 100 MPa at 300.degree. C. and a formability greater than 0.9 true strain, as measured at room temperature (22.degree. C.) with a strain rate of 8.7 sec.sup.-1.
- 8. Aluminum alloy as claimed in claim 1, consisting essentially of 6 to 10 wt.-% Fe, 2 to 9 wt.-% Ce, remainder substantially Al.
- 9. An assembly as claimed in claim 6, said fasteners comprising rivets.
