The disclosure provides an aluminum alloy may include iron (Fe) of at least 0.10 wt %, silicon (Si) of at least 0.35 wt %, and magnesium (Mg) of at least 0.45 wt %, manganese (Mn) in amount of at least 0.005 wt %, and additional elements, the remaining wt % being Al and incidental impurities.

Recycled aluminum alloys from manufacturing scrap with cosmetic appeal

The disclosure provides an aluminum alloy including having varying ranges of alloying elements. In various aspects, the alloy has a wt % ratio of Zn to Mg ranging from 4:1 to 7:1. The disclosure further includes methods for producing an aluminum alloy and articles comprising the aluminum alloy.

Aluminum alloys with high strength and cosmetic appeal

Composite structures that have an appearance of an anodized bulk metal but that is non-capacitive and/or radio frequency (RF) transparent are disclosed. The composite structure can be part of an enclosure of an electronic device. The composite structure can give the enclosure a metallic look without interfering with the functioning of some electronic components of the electronic device, such as RF antennas, touch pads and touch screens. Some embodiments involve forming a metal oxide layer and depositing a non-capacitive layer on the metal oxide layer. Some embodiments involve forming an imitation metal oxide layer and depositing a non-capacitive layer on the imitation metal oxide layer.

Non-capacitive or radio frequency-transparent materials with anodized metal appearance

A metal part is surface treated using anodization and plating processes to produce different finishes on selective regions of the metal part. The different finishes can contrast in decorative appearance (such as color, shininess and texture) and structural properties (such as wear resistance).

Anodization and plating surface treatments

Polymer materials that are color-matched with non-polymer materials are disclosed. Methods involve incorporating the same type of dyes used to colorize the non-polymer materials within the polymer materials. In some embodiments, a solvent casting process is used, which involves dissolving a polymer material and a dye with a solvent or a combination of solvents forming a dye-polymer mixture. In some embodiments, the dye-polymer mixture is dispensed onto a carrier and the solvent is removed forming a dyed polymer layer that can be applied onto a part as a color veneer. In some embodiments, the dye-polymer mixture is dispensed into mold and the solvent is removed forming a dyed polymer structure that can be used as a stand-alone structure or as part of a larger structure.

Color-matched polymer materials and method for forming the same

A constant force finishing system used to finish a surface of a workpiece includes at least a first movement device arranged to apply a first movement to a finishing tool, the first movement having a range of distance D. The finishing system also includes a constant force device (CFD) in mechanical communication with the finishing tool, the CFD arranged to apply a second movement in conjunction with the first movement to the finishing tool, the second movement having a range of &#x394;, where D&#x3e;&#x3e;&#x394;.
