摘要

Alcoa Inc. announced that its aluminium lithium plate is featured in NASA's friction-stir welded, spun-form dome that makes its debut at the end of March at the Marshall Space Flight Center in Huntsville, Alabama. Along with Lockheed Martin and MT Aerospace, Alcoa engineers were part of the consulting team providing materials expertise that helped to develop this groundbreaking technology - the first full-scale friction-stir welded and spun-formed tank dome designed for use in large liquid propellant tanks.
