Rivet code D corresponds to which aluminum alloy?

Explanation:
Rivet code letters are a quick way to identify the aluminum alloy and temper used for rivets. Each letter on the chart maps to a specific alloy and heat treatment. The D code is defined to designate the 2017-T aluminum rivet alloy. The 2017-T alloy is a medium-strength aluminum that, when tempered to T, is heat-treated to develop its strength for structural rivets. This is why D corresponds to 2017-T. Other alloys listed—such as softer 1100, higher-strength 2024-T, or magnesium-containing 5056-T—have different designations on the rivet-code chart, so they wouldn’t correspond to the D code.
