Bombardier, the Canadian transportation company, is taking a close look at new aluminum-lithium alloys for its C-Series Aircraft under development. Under particular study is the 2099 grade for use as extrusions for internal structure and 2199 sheet and plate for fuselages and lower wring applications. The new alloys reduce weight and improve performance of aircraft. The new planes aren’t expected to take flight until 2013. One potential customer is China Aviation Corp., a development partner with Bombardier.
Oak Ridge National Laboratory has developed a surface preparation method to improve joining carbon composites with aluminum, with potentially far-reaching ramifications for high-volume industrial applications.
