Al-Mg based alloy sheets with good press formability

By careful control of composition and processing, Al--Mg based alloy sheets with preferred grain sizes and crystallographic textures that result in good press formability are disclosed. The Al--Mg alloy preferably contains 2-6 wt % Mg, and at least 0.03 wt % of at least one element selected from Fe, Mn, Cr, Zr, and Cu. The crystallographic texture is comprised of grains with a volume fraction in a range of about 5% to 20% in the CUBE orientation {100} &lt;001&gt;, a volume fraction in a range of about 1% to 5% in the GOSS orientation {110} &lt;001&gt;, a volume fraction in a range of about 1% to 10% in each of the BRASS orientation {110} &lt;112&gt;, S orientation {123} &lt;634&gt;, and COPPER orientation {112} &lt;111&gt;, wherein the grain size is in a range of about 20 to 70 .mu.m.
