The Shear Assisted Processing and Extrusion (ShAPETM) project shows the potential to increase throughput and reduce manufacturing costs and energy use for aluminum alloy 7075 extrusions. Aluminum alloy 7075 (AA7075) is a high-strength, low-weight metal alloy that can handle heavy mechanical stresses.
Ritchey Metals, a Canonsburg, Pa.-based manufacturer of zinc alloys, entered into a joint venture with Imperial Group to serve the nonferrous alloyed metals industry in the southern half of the United States. Chicago-based Imperial Group, which consists of 17 industrial entities, is a diversified metals group moving nearly 75 million pounds of metal per month. The joint venture will utilize Imperial Group’s plant in Scottsboro, Ala., which will add capabilities to service the market stretching all from the East Coast to the Southwest. Ritchey Metals operates two facilities in southwestern Pennsylvania, each with multiple industrial furnaces.
Retrogression heat treatment and re-aging (RRA) is used for retaining optimal strength in aluminum alloys while avoiding stress corrosion cracking (SCC). Last time, we learned about the SCC phenomenon and its effects on aluminum alloys.
Retrogression heat treatment and re-aging (RRA) is used for retaining optimal strength in aluminum alloys such as 7075-T6 while avoiding stress corrosion cracking and for improving formability of aluminum components such as extrusions.
QuesTek Innovations LLC and the German Aerospace Center, in a joint effort, will explore the full potential of QuesTek’s new printable aluminum (Al) alloy, which was developed for additive manufacturing (AM). The alloy is capable of high-strength performance at elevated temperatures (200-300°C/392-572°F) in the as-built condition. It is believed to be the first powdered AI material to meet those requirements without the need for subsequent heat treatment. The alloy will enable the printing of lighter-weight precision components not currently possible with traditional manufacturing methods, including heat exchangers or other components requiring internal cooling channels.
When heat treating aluminum and aluminum alloys, it is important to understand the challenges we face and why absolute control of process and equipment variability is so very critical.
Novelis Inc. announced a $4.5 million manufacturing investment at its facility in Warren, Ohio. The investment in state-of-the-art technology provides greater versatility for pretreatments, improves operational efficiency and reduces costs. The company’s Warren facility has 75 employees dedicated to applying coating to rolled aluminum sheet used for production of lids for the tops of aluminum beverage cans.
Sintavia LLC of Davie, Fla., developed full end-to-end parameters for producing additively manufactured parts in F357 aluminum, as well as other Al-Si alloys, for use in precision manufacturing.
