Traditionally, aluminum has been the most important raw metal material for the aerospace industry. Since the major part of aluminum production is consumed for aircraft, military, space, and other programs, sponsored or regulated by the U. S. Government, quality of various Al alloys is under governmental control. The representatives of the governmental agency are placed at each aluminum plant in order to assure a high quality of production on-site. A fast and reliable analytical method is essential to control the production process and to keep chemical composition of the alloys inside specified ranges.
