The present invention, in some embodiments, is a method of forming an O temper or T temper product that includes obtaining a coil of a non-ferrous alloy strip as feedstock; uncoiling the coil of the feedstock; heating the feedstock to a temperature between a recrystallization temperature of the non-ferrous alloy and 10 degrees Fahrenheit below a solidus temperature of the non-ferrous alloy; and quenching the feedstock to form a heat-treated product having am O temper or T temper. The non-ferrous alloy strip used in the method excludes aluminum alloys having 0.4 weight percent silicon, less than 0.2 weight percent iron, 0.35 to 0.40 weight percent copper, 0.9 weight percent manganese, and 1 weight percent magnesium.

Methods of off-line heat treatment of non-ferrous alloy feedstock

Systems and methods for continuously casting Al&#x2014;Mg alloy sheet or plate product having a high amount of magnesium are disclosed. The Al&#x2014;Mg products have 4 or 6 to 8 or 10 wt. % Mg and are resistant to both stress corrosion cracking and intergranular corrosion.

Corrosion resistant aluminum alloys having high amounts of magnesium and methods of making the same

An aluminum alloy product and method for producing the aluminum alloy product that, in some embodiments, includes an aluminum alloy strip having at least 0.8 wt. % manganese, at least 0.6 wt % iron, or at least 0.8 wt. % manganese and at least 0.6 wt % iron. A near surface of the aluminum alloy strip, in some embodiments, is substantially free of large particles having an equivalent diameter of at least 50 micrometers and includes small particles. Each small particle, in some embodiments, has a particular equivalent diameter that is less than 3 micrometers, and a quantity per unit area of the small particles having the particular equivalent diameter is at least 0.01 particles per square micrometer at the near surface of the aluminum alloy strip.

Aluminum alloy products and methods for producing same

New 6xxx aluminum alloy strips having an improved combination of properties are disclosed. The new 6xxx new aluminum alloy strips are rolled to a target thickness in-line via at least a first rolling stand and a second rolling stand. In one approach, the 6xxx new aluminum alloy strips may contain 0.8 to 1.25 wt. % Si, 0.2 to 0.6 wt. % Mg, 0.5 to 1.15 wt. % Cu, 0.01 to 0.2 wt. % manganese, 0.01 to 0.2 wt. % iron; up to 0.30 wt. % Ti; up to 0.25 wt. % Zn; up to 0.15 wt. % Cr; and up to 0.18 wt. % Zr.

Methods of continuously casting new 6xxx aluminum alloys, and products made from the same

A method of making aluminum alloy sheet in a continuous in-line process is provided. A continuously-cast aluminum alloy strip is optionally quenched, hot or warm rolled, annealed or heat-treated in-line, optionally quenched, and preferably coiled, with additional hot, warm or cold rolling steps as needed to reach the desired gauge. The process can be used to make aluminum alloy sheet of T or O temper having the desired properties, in a much shorter processing time.

In-line method of making heat-treated and annealed aluminum alloy sheet

Coil rack

An aluminum alloy sheet and a method for producing an aluminum alloy sheet. The aluminum alloy sheet is useful for forming into drawn and ironed container bodies. The sheet preferably has an after-bake yield strength of at least about 37 ksi and an elongation of at least about 2 percent. Preferably the sheet also has earing of less than about 2 percent.
