ALUMINUM AEROSPACE PLATE

With air travel projected to grow substantially over the next several years, the aerospace industry is building new aircraft to accommodate a growing number of air passengers and to replace older, less effi cient planes with newer, more fuel-effi cient models. Aluminum offers a high strength-to-weight ratio, energy effi ciency, and high tolerance to extreme temperatures making it an ideal material for the manufacturing of aircraft. It can also be recycled repeatedly, making it a good choice as manufacturers pursue sustainability initiatives.

In order to help aerospace Original Equipment Manufacturers (OEMs) to develop and build light and cost-effi cient passenger and cargo aircrafts with lower fuel burn, reduced emissions and longer ranges, it has become increasingly important for us to technically support our customers programs with the very best solutions.

Working closely with OEMs, Aleris has developed aerospace products to meet the most stringent specifi cations to ensure the materials properties, which include thickness, fatigue resistance, toughness and ductility, will optimize the performance of the aircraft structure.

ADVANTAGES OF DAMAGE TOLERANT ALUMINUM PLATES:

thickness up to 280 mm (11) no signifi cant porosity excellent fatigue performance extreme low level of residual

stresses practically no distortion after

machining high strength high ductility excellent toughness

RESEARCH AND DEVELOPMENT

Aleris has concentrated its research and development work in fi ve innovation centers, whereby the center at the Koblenz plant is specifi cally responsible for research and development in the aerospace sector.

To support customers in Asia Pacifi c, Aleris also invested in an innovation center in its Zhenjiang facility to support commercial plate and aerospace applications.

In Aachen there is another innovation center for more blue-sky, fundamental and cross-sector research purposes. The engineers there are responsible for developing new aluminum products with improved properties under laboratory conditions, which includes experimental trials and theoretical simulations. They also carry out small-scale testing of alloys and processes. As well as its strategic geographic location, Aachen offers close connections to the research facilities of RWTH Aachen University, one of the most respected higher education centers in the world. Aleris is one of the partners in the AMAP (Advanced Metals and Processes) cluster, working closely with university institutes and other industry partners on pre-competitive advanced solutions.

CORE RESEARCH AREAS

The core research areas for Aleris in the aerospace industry include advanced hard alloys and reduced-density alloys such as AlMgSc. Aleris can develop and test all major production and processing stages as pilot processes at the production scale.

Furthermore, all innovation centers use the latest analysis techniques, microscopes, x-ray machines, testing and measurement apparatus, partly in cooperation with external partners. The special aerospace equipment in Koblenz includes a trial casting machine, which allows casting of industrial-scale ingots for test programs. Our laboratory with new equipment continuously added supports our research efforts, whether it is alloy development or process improvement.

We can thus reliably and comprehensively provide our customers all information that is required to manufacture an optimal product.

CASE STUDY AEROSPACE:CLOSED LOOP RECYCLING

To reduce the need for primary aluminum as well as manufacturing waste, Aleris works with customers to create closed loop processes, in which customers send their waste back to Aleris to be recycled into new products. Aleris has established closed loop processes with aerospace customers that incorporate quality, logistics, volume and schedule requirements to ensure that product needs are met and that the appropriate scrap is collected and returned to Aleris for recycling.

SUSTAINABILITY

At Aleris, sustainability has always been core to our business. With both the know-how and the experience to partner with customers to help them capitalize on the unlimited potential of aluminum, we are helping to drive sustainable solutions, and supporting trends such as more fuel-effi cient airplanes.

We believe that Aleris and aluminum play an important role in improving the sustainability performance of the customers we serve. We are working to reduce our environmental footprint, and increase the use of recycled content in our products.

Our primary sustainability objective is to produce and sell increasingly sustainable aluminum products. We continuously work to develop innovative solutions that will better position aluminum as the material of choice for customers and consumers seeking high-performance solutions that will also reduce their carbon footprint.

We have partnered with customers to: understand their key business and

sustainability drivers to inform new product development,

implement closed loop manufacturing processes to help our customers reduce waste and incorporate more recycled content into their products,

pursue life cycle assessments (LCAs) and environmental certifi cation to quantify the environmental benefi ts of certain products.

BENEFITS OF CLOSED LOOPSOLUTIONS

A reduction in greenhouse gases and other environmental impacts through the use of recycled content aluminum as opposed to primary aluminum.

Improved business continuity for both partners as the supply is guaranteed through this agreed process.

The creation of a consistently high grade of aluminum alloy as nothing is lost via downcycling to lower alloys.
