Given the limited availability of domestic scrap and the long product life cycles of aluminum in construction and autos, North American producers may increase imports of foreign scrap and primary aluminum. 0 The n

Changing dynamics in regional markets are affecting primary production centers. Periods of volatility i

For the near to mid term, operations will continue to be attracted to locations that offer stable, affordable electricity, whether it is provided by low-sulfur-cod, advanced hydropower, or alterna

Global economic factors will make it highly unlikely that any new Hall-Heroult smelters will be built in the United States. Continued operation of existing facilities will depend on the availability of rel

Advanced casting and extrusion technologies have attracted the interest of the research community. Developments in these areas, such as wide-s

12、heet casting technology, new or enhanced extrusion capabilities, and other innovations, will increase aluminum use in automotive applications. Producers will enter agreements with automakers and other customer industries to directly supply customized aluminum components. “Smart” fabrication systems

Such systems eventually will control the manufacturing process from beginning to end, continuously monitoring and adjusting process conditions and optimizing system efficiency. Technology innovations will enable design and production of aluminum with spec

Examples include specific micro-structural textures in sheet products and unique profile cross-sections in extru

Manufacturing of new materials at the molecular level will enable aluminum producers to create innovative, high- performance materials for highly specialized use in transportation, computers, energy, and communications. Nano-technology goods and

As shown in Figure 7, electricity prices for the industrial sector are expected to decline 0.6 percent nationwide over the period 1999-20

19、20, with some regional variation. They are projected to increase by 0.3 percent in the Northwest Power Pool and to fall by 0.5 percent in the East Central Area Reliability (ECAR) Council. On average, electricity prices will drop from 2001 until approximately 2008, hold steady until about 2015, and b

Although restructuring is expected to lower long-term electricity prices, price volatility is likely over the next five to sev

21、en years. Electricity prices will increase in some parts of the country and decrease in others-a result of regional differences in demand, natural gas prices, transmission capacity, and other market conditions.* New electrical power capacity will be built. The United States will need to build betwee

22、n 1,300 and 1,900 new power plants by 2020. Currently, large amounts of new generating capacity are slated for installation around the country between 2001 and 2004. However, a geographic mismatch exists between where energy will be generated and needed. Environmental issues will exert a major impac

23、t on the availability and cost of electricity. Risk-reduction strategies will be popular. Some firms are already planning for a radically altered future by building their own power plants and switching their focus from basic aluminum to higher-tech products. Aluminum producers will need to work with

Alternative distributed energy resources (wind, solar, and other) will offer new opportunities for electricity in the

25、 2020 time frame. . HUMAN RESOURCES Y - I. . .,. I The energy-intensive smelting process converts electrical energy into a usable and stable material: in essence, aluminum is an “energy bank.” Aluminums amazing recyclability ensures that deposits made to this bank will preserve value. While more ene

26、rgy-efficient smelting technologies are being developed, the energy put into aluminum production remains intact in the recycling loop. The industry will cut smelting energy use to 11 kWh/kg or less by 2020 and achieve additional energy targets set by existing and future industry roadmaps. Technology

27、 advances in cell design and materials such as non-consumable anodes will conserve resources, reduce emissions, and eliminate disposal issues. While technology development is underway to cut energy use in primary production, aluminum will continue to reduce fuel use by an average of 5-8 percent for

28、every 10-percent reduction in the weight of todays vehicles. By 2050, the industry will reduce its energy consumption until it eliminates any energy disadvantage in competing with other materials on a full life-cycle basis. At that point, far more efficient smelting technology will have replaced the

29、 Hall-Heroult process. TECH NO LOGY By employing some of the best talent in all of manufacturing, the aluminum industry will pioneer new technologies for enhancing aluminums unique properties to meet customer needs. Material engineering will require advanced understanding of microstructures and the

30、creation of extensive technical databases for predicting the properties that can be achieved in various alloys and composites. The industry will actively build such databases through corporate efforts or through public-private R&D partnerships in conjunction with universities and national laboratori

31、es. In addition to its own technology developments, the aluminum industry will look to other process industries for solutions to some of its key technical issues. Advancements in modeling techniques, sophisticated control systems, and materials treatment and handling may be tailored to improve alumi

33、rrow will depend on the industrys ability to effectively communicate aluminums life-cycle value. It must clearly imprint aluminum as “sustainable” in the minds of investors, users, employees, politicians, regulators, and other stakeholders. Toward this end, the industry will launch an ambitious comm
