7039 aluminium alloy

AA 7039 is an aluminum alloy principally containing zinc (3.5–4.5%) as an alloying element. It also contains 0.30% silicon, 0.40% iron, 0.10% copper, 0.10–0.40% manganese, 2.3–3.3% magnesium, 0.15–0.25% chromium, 0.10% titanium and up to 0.15% trace elements.[1]:11 The density of 7039 aluminium is 2740 kg/m3.[1]:19

This alloy was first registered in 1962, in the United States.[1]:11
