By Kevin Widlic, Contributing Editor. Hangarbrua, a pedestrian and cycle bridge built with aluminum from a decommissioned offshore oil platform, has been lifted into place in Trondheim, Norway, and will open this fall. The Norwegian Public Roads Administration expects the bridge to be maintenance free for 100 years, and a life cycle analysis shows that […]
By Dr. Anne Deacon Juhl, AluConsult and AnodizingSchool. Recycled aluminum, when properly processed, can deliver anodized finishes indistinguishable from primary aluminum. While higher levels of trace elements, like zinc (Zn), copper (Cu), and iron (Fe), can increase sensitivity to corrosion or surface defects, these challenges are often smaller than variations caused by production methods and […]
By Alicia Hartlieb and Martin Hartlieb, Viami International Inc. Structural die castings for car bodies have been around for more than 30 years, and they have been growing in size and complexity. Many cars today already have parts like shock towers, cross members, and/or long side members made from structural aluminum die casting. Sometimes, even […]
Century Aluminum Company has announced plans to restart over 50,000 MT of idled production at its Mt. Holly, SC smelter. The company will invest approximately $50 million in the effort, creating over 100 new jobs and boosting U.S. primary aluminum output by nearly 10%. The restart will bring the plant, now at 75% capacity, to […]
By Dr. Anne Deacon Juhl, AluConsult and AnodizingSchool. Recycling aluminum is recognized worldwide as one of the most effective ways to reduce waste, conserve natural resources, and lower environmental impact. The process of anodizing, which involves treating aluminum to create a durable, corrosion-resistant surface, plays a crucial role in making aluminum more versatile and environmentally […]
By S. Tichy, K. Büchner, S. Wibner, and H. Antrekowitsch, Montanuniversität Leoben, Chair of Nonferrous Metallurgy; and P. Pucher and B. Prillhofer, AMAG casting GmbH. Natural gas is commonly used as an energy source in aluminum recycling furnaces, particularly for achieving high melting throughputs. While the direct use of electrical energy has the potential to […]
By F. Eberl, J.P. Masse, and B. Davo, Constellium. In aircraft wing structure design, two types of concepts predominate today — largely metallic aluminum wing structures used for short-medium range, single-aisle aircraft, such as the Airbus A320 or Boeing B737, and largely composite wing covers used for the latest long-range, twin-aisle aircraft, such as the […]
Metra Group, headquartered in Rodengo Saiano, Italy, is a global manufacturer of complex extruded aluminum profiles, supporting the needs of industrial, building and construction, and other markets. A key strategic sector for the company for decades has been the railroad industry, which is seeing growing demand for aluminum as the industry focuses on improving the […]
Emirates Global Aluminium (EGA) plans to invest $4 billion in the construction of a new aluminum smelter in the U.S., making it the first primary aluminum production plant to be built in the U.S. in 45 years. The company recently signed an MOU with Governor Kevin Stitt to locate the proposed smelter in Oklahoma. “The […]
