Provided herein are novel, high-forming multi-layer aluminum alloy packages that include a core layer and one or more cladding layers. The alloy packages have excellent bake-hardening properties and are highly recyclable. The packages also display exceptional bendability and elongation properties. Also provided herein are novel aluminum alloy compositions for use as cladding layers. The compositions contain up to 0.6 wt. % Fe and one or more of Mn, Ni, Ti, Co, Nb, Cr, V, Zr, Hf and Ta.

High-forming multi-layer aluminum alloy package

Provided are new high strength 6xxx aluminum alloys and methods of making aluminum sheets thereof. These aluminum sheets may be used to fabricate components which may replace steel in a variety of applications including the transportation industry. In some examples, the disclosed high strength 6xxx alloys can replace high strength steels with aluminum. In one example, steels having a yield strength below 340 MPa may be replaced with the disclosed 6xxx aluminum alloys without the need for major design modifications.

Moving metal strips can be heat treated with any number or combination of dimensionally variable tempers across widths, lengths, or thicknesses of a metal strip. To provide dimensionally variable heat treatment, an apparatus can include one or more heating units suitable to increase the temperature of a metal strip moving proximate the apparatus to a heat treatment temperature. The apparatus can also include one or more cooling units positioned near the heating units to absorb heat and cool the metal strip to minimize the amount of heat transferred from a first region of the metal strip that is to be treated to a second region of the metal strip that is not to be treated.

Metal sheet with tailored properties

Described herein are compounds for use in coating compositions and methods of using the same. Also described herein is a method of treating metal products (e.g., aluminum alloy products), including applying the coating composition to at least one surface of the metal product. Further described herein is a joined structure, including the coated aluminum alloy product and another metal or alloy. The coating compositions enhance the bond performance of the joined structures.

Provided herein are systems and methods for producing thick gauge aluminum alloy articles such as plates, shates, slabs, sheet plates or the like. A method for producing thick gauge aluminum alloy articles can include continuously casting an aluminum alloy article and hot or warm rolling the aluminum alloy article. Also provided herein is a continuous casting system for producing thick gauge aluminum alloy articles. The disclosed thick gauge aluminum alloy articles can be provided in any suitable temper.

Systems and methods for making thick gauge aluminum alloy articles

Provided herein are new clad aluminum alloy products and methods of making these alloys. These alloy products possess a combination of strength and other key attributes, such as corrosion resistance, formability, and joining capabilities. The alloy products can be used in a variety of applications, including automotive, transportation, and electronics applications.

Clad aluminum alloy products

A continuous casting and rolling line for casting, rolling, and otherwise preparing metal strip can produce distributable metal strip without requiring cold rolling or the use of a solution heat treatment line. A metal strip can be continuously cast from a continuous casting device and coiled into a metal coil, optionally after being subjected to post-casting quenching. This intermediate coil can be stored until ready for hot rolling. The as-cast metal strip can undergo reheating prior to hot rolling, either during coil storage or immediately prior to hot rolling. The heated metal strip can be cooled to a rolling temperature and hot rolled through one or more roll stands. The rolled metal strip can optionally be reheated and quenched prior to coiling for delivery. This final coiled metal strip can be of the desired gauge and have the desired physical characteristics for distribution to a manufacturing facility.

Metal casting and rolling line

Described are processes for shaping age hardenable aluminum alloys, such as 2XXX, 6XXX and 7XXX aluminum alloys in T4 temper, or articles made of such alloys, including aluminum alloy sheets. The processes involve heating the sheet or article before and/or concurrently with a forming step. In some examples, the sheet is heated to a specified temperature in the range of about 100-600&#xb0; C. at a specified heating rate within the range of about 3-600&#xb0; C./s, for example about 3-90&#xb0; C./s. Such a combination of temperature and heating rate results in an advantageous combination of sheet properties.

Described herein are pretreatment compositions, coated aluminum alloy products, and methods for coating the alloys. The pretreatment compositions include inorganic chemical corrosion inhibitors dispersed in a silane-based matrix and may further include clay particles. The inorganic chemical corrosion inhibitors include rare earth metals and salts thereof. The pretreatment compositions, when applied to the surface of an alloy, inhibit corrosion of the alloys. The pretreatment compositions can be used in automotive, electronics, industrial, transportation, and other applications.

Pretreatment compositions, coated aluminum alloys, and methods of making the same

Described are processes for shaping a hardened heat treatable, age-hardenable aluminum alloys, such as hardened 2XXX, 6XXX and 7XXX aluminum alloys, or articles made from such alloys, including aluminum alloy sheets. The processes involve heating the article, which may be in a form of a sheet or a blank, before and/or concurrently with a forming step. In some examples, the alloy is heated to a specified temperature in the range of 125-425&#xb0; C. at a specified heating rate within the range of about 3-200&#xb0; C./s, for example, 3-90&#xb0; C./s or 90-150&#xb0; C./s. Such a combination of the temperature and the heating rate can result in an advantageous combination of article properties.
