20100018617 | ALUMINUM ALLOY FOR ANODIZING HAVING DURABILITY, CONTAMINATION RESISTANCE AND PRODUCTIVITY, METHOD FOR PRODUCING THE SAME, ALUMINUM ALLOY MEMBER HAVING ANODIC OXIDE COATING, AND PLASMA PROCESSING APPARATUS - The aluminum alloy for anodic oxidation treatment directed to the present invention comprises as alloy elements 0.1 to 2.0% Mg, 0.1 to 2.0% Si, and 0.1 to 2.0% Mn, wherein each content of Fe, Cr, and Cu is limited to 0.03 mass % or less, and wherein the remainder is composed of Al and inevitable impurities. An aluminum alloy more excellent in the durability can be obtained by subjecting the aluminum alloy ingot having the above element composition to a homogenization treatment at a temperature of more than 550° C. to 600° C. or less. An aluminum alloy member can be obtained by forming an anodic oxidation coating on the surface of the aluminum alloy. | 01-28-2010 |
20100037997 | ALUMINUM ALLOYS FOR DISPLAY FRAMES - Described is a method for forming an internal frame configured to receive a flat screen display. Aggressive partial annealing is applied to a hard temper 5182 aluminum alloy material having magnesium content greater than or equal to 3.0 wt. %. The material is partial annealed to an extent that the hard temper aluminum alloy is substantially softened with respect to its initial hardened temper while not exceeding the point where recrystallization occurs. An internal frame for a flat screen display is formed from the partial annealed aluminum alloy. | 02-18-2010 |
20120234439 | Method to Improve the Corrosion Resistance of Aluminum Alloys - Aluminum-magnesium alloys are ideal for ship construction; however, these alloys can become sensitized and susceptible to intergranular corrosion when exposed to moderately elevated temperatures. A stabilization treatment has been developed to reverse sensitization and restore corrosion resistance, such that in-service plate can be refurbished rather than replaced. This treatment involves a short exposure to a specific elevated temperature range and can be implemented with portable units onboard a ship. | 09-20-2012 |
