Aluminum Alloy 2099

 

Aluminum alloy 2099 extruded shapes and plate products reduce weight because of the alloy's lower density and improved mechanical properties. The weight of aircraft floor beams and seat tracks made from 2099-T83 extrusions, lower wing stringers made from 2099-T8E67 extrusions, and aircraft components made from 2099-T8E77 plate is 7-17% lighter than the alloys/products conventionally used in these applications. The lower weight translates into highly desirable reductions in fuel consumption and CO2 emissions.

Aluminum alloy 2099 also improves reliability, as the expected lifetime of aircraft components made from aluminum alloy 2099 extruded shapes and plate products is 1.5 to 3 times higher than the alloys/products conventionally used. By controlling and refining the composition, temper, and microstructure, aluminum alloy 2099 product exhibits improved resistance to corrosion and crack propagation. Because aircraft parts made from 2099 extruded-shape and plate products are more reliable, they can withstand more fatigue damage and last longer than parts made with other alloys. These improvements in durability and damage tolerance - which are measured by resistance to the growth of fatigue-induced cracks, fracture toughness, and resistance to stress corrosion cracking - ultimately produce an aircraft that is safer and less costly to maintain.
