Method of producing high tensile aluminum-magnesium alloy sheet and the products so obtained

A method of producing high tensile aluminum-magnesium alloy sheet from an aluminum-based melt containing a relatively low percentage of magnesium, such as 1.5-2.3%, in which the melt is formed into a sheet having a uniform thickness between 1/8-1/2 inch quenched to a temperature below about 500 DEG...

Beschreibung
Zusammenfassung:	A method of producing high tensile aluminum-magnesium alloy sheet from an aluminum-based melt containing a relatively low percentage of magnesium, such as 1.5-2.3%, in which the melt is formed into a sheet having a uniform thickness between 1/8-1/2 inch quenched to a temperature below about 500 DEG F. within a period of not more than three (3) minutes, in which the quenched sheet is cold rolled straight down to a thickness between 0.01 and 0.02 inch without the application of extraneous heat to the sheet. The resulting aluminum-magnesium alloy sheet has a fully-hardened tensile strength in excess of 50,000 psi.
