Online Exclusive: Trends in Aluminum, Magnesium, and Titanium Discussed in South Africa

The Advanced Metals Initiative (AMI) Light Metals Conference 2014 was held in October 2014 in South Africa, bringing together researchers, government, and industry players for a Bushveld Lekgotla* that sought to share, debate, and deliberate on the latest trends, research, and innovative solutions in the field of light metals. The conference was hosted by the Council for Scientific and Industrial Research (CSIR).

Light Metal Age has made available an online exclusive article reviewing the proceedings of the AMI Light Metals Conference.

Aluminicaste Completes New Remelt Facility in Mexico – Free Article Download


Billet stacked and ready for shipment
at Aluminicaste, Guanajuato State, Mexico.

The February 2014 issue of Light Metal Age features an article on the new aluminum greenfield remelt facility located in Guanajuato State, Mexico. Aluminicaste is close to full production capacity, producing primarily extrusion billet, but also capable of manufacturing world class rolling ingot and forging/large press billet, in both hard and soft alloys on their two DC casting lines. This product mix and the ability to cast both hard and soft alloys make the Aluminicaste plant unique in the flexibility of products it can produce.

This article, which Aluminicaste has made this article available as a free download via its website, describes the concepts of the location, plant configuration, and market focus for what has been completed in this initial phase, as well as the expansion potential that will take the plant from the largest remelt in Mexico to being one of the largest operations of its kind on the entire North America continent.

Maadi Group CEO Talks Structural Design – Free Article Download

In our April 2013 issue, Light Metal Age interviewed the president and ceo of MAADI Group Inc., Alexandre de la Chevrotiere in order to discuss the overall history and business of MAADI and its work on bridge construction and civil and maritime structures. In the article, de la Chevrotiere points to aluminum’s advantages in structural design, as well as lifecycle considerations for aluminum versus steel bridge structures.  He also looks at a report on the importance of upgrading the bridge infrastructure in North America and MAADI’s technical guidelines for its structural design projects and aluminum alloy selection at the company.

MAADI has made this interview available as a free download via its website.

Online Exclusive: Aluminum Rises High on a Green Foundation at Greenbuild

The world’s largest conference and expo dedicated to green building, Greenbuild 2010 was held November 17-19 at McCormick Place West in Chicago, IL. Around 28,000 attendees came together at Greenbuild for three days of educational sessions, green building tours, special seminars, and networking events.

Greenbuild is managed and organized by the U.S. Green Building Council (USGBC), a national nonprofit organization working to promote buildings that are environmentally responsible, profitable, and healthy to live and work in. The USGBC developed the LEED (Leadership in Energy and Environmental Design) Green Building Rating System, which provides a recognized standard for the building and construction industry in assessment of the environmental sustainability of building designs. Greenbuild showcased the use of aluminum in the form of sheet and extrusions in green buildings, with aluminum’s sustainability being a major topic of discussion at the show.

Online Exclusive: International Temper Designation Systems for Wrought Aluminum Alloys

The globalization of the aluminum industry has made it imperative that universal alloy and temper designations be adopted worldwide. Already, there is an international accord regarding the designation and composition of aluminum and aluminum alloys, published by The Aluminum Association in TEAL SHEETS 2009. However, there still is no international accord on designation and registration of tempers for wrought aluminum and aluminum alloy products, although this is changing slowly but surely. A joint ANSI H35.1, EN 515, and ISO 2107 technical committee on a unified temper designation system has been established and meets periodically.

In the meantime, the aluminum industry conducts business worldwide and manages to translate and work with the different temper standards for wrought products established country-by-country. Thus, this two-part article series attempts to summarize the present worldwide status of temper designations and meanings for wrought aluminum and aluminum alloys classified as either strain hardenable (Part 1) or thermally treated (Part 2). In the first article (Part 1), the temper designations for 1xxx, 3xxx, and 5xxx alloys are reviewed with respect to the H temper designations standardized in the U.S. in ANSI H35.1-2009 and European CEN countries in EN 515. In the second article (Part 2), the temper designations for thermally treated – most commonly 2xxx, 6xxx, and 7xxx alloys – are reviewed with respect to T temper designations. At the same time, definitions and comparisons are made between these new and the older temper designations, e.g., outdated German DIN and English BS, wrought aluminum temper designations, and country-specific temper designations that may still be in existence.

Online Exclusive: Reliability of FEM Codes for Aluminum Extrusion Process Analysis

The International Conference on Extrusion and Benchmark (ICEB) is an event aimed at promoting the most recent advances in aluminum extrusion technologies with a specific session dedicated to the evaluation of the reliability of FEM codes for process analysis. At the 2009 conference, organized in Dortmund in September 2009, there was great interest in the subject of improvement of FEM code capacity for simulation and optimization of the extrusion process.

As an exclusive to Light Metal Age, the papers related to FEM code description, as presented by the authors during the conference, are offered here. The papers describe the most recent developments and capabilities of Deform, MTD, and QForm code. Each paper includes details of the main features of the code, the required procedure for model set-up, and the most recent improvement performed in the solving approaches, and in pre- and post-processing interface. Finally, a comparison between FEM code outputs and experimental trials on selected industrial case studies are presented and discussed.
