The American Iron and Steel Institute continues its advanced-technology programs, while the Bush Administration seeks an investigation of low-priced steel imports. President Bush's decision to petition the International Trade Commission (ITC) is a major victory for AISI and the United Steelworkers of America union; they've been lobbying since allegations of foreign dumping began in 1997. The U.S. steel industry's downfall can be attributed to rising energy prices and the conversion of many automotive applications to alternative materials. AISI hopes new technologies — intrusion protection has been improved and door weight reduced — will help the industry rebound. Meanwhile, use of aluminum may grow 50% by 2006 with increasing pressure to improve light-truck fuel economy. Richard L. Klimisch, vice president of the Aluminum Assn.'s auto and light truck group, says manufacturers are using more aluminum in frames, engines, lift gates, fenders and hoods.
