Abstract

See full text

This aluminum alloy sheet is a 6000-series aluminum alloy sheet of a specific composition which, after rolling, has undergone solution hardening and reheating as tempering treatments. The aluminum alloy sheet in differential scanning calorimetry gives a curve in which the exothermic-peak heights A, B, and C in respective specific temperature ranges have relationships within specific given ranges to thereby raise the increase in 0.2% proof stress through low-temperature short-time artificial age-hardening to 100 MPa or more.
