MACHINING NEW MATERIALS
improved material properties allow optimized structural designs, and lighter aircraft produce fewer CO2
emissions.
One of the key global suppliers of aluminum-lithium is Constellium (Paris). Its Airware aluminum-lithium is the result of decades of R&D to support innova- tive aerospace programs, according to the company. Airware was launched in 2010 as a comprehensive offer of high-performance aluminum-lithium alloys that are well suited for all parts of the primary aerostructure. In addition to aluminum and lithium, Airware alloys also contain copper and silver as major additional elements. “Airware guarantees higher durability due to its greater resistance to fatigue and corrosion, which enables airlines

MACHINE TOOL FILTRATION JUST GOT A LOT MORE ATTRACTIVE...
■ Minimal set-up
■ Ensures “ultra-polished” machine tool fluids
■ Superior removal of ferrous contamination
■ High intensity magnetic core and patented fluid flow path
■ Non-block design
■Works on or off-line, taking dirty fluid from the holding tank and returning clean fluid
to target extended heavy maintenance intervals,” said Sylvain Henry, direc- tor, customer application engineering for Constellium. “Airware is endlessly recyclable without any loss of properties and contributes to the development of a sustainable aerospace industry.” He noted that Airware is already fl ying on major aerospace programs such as the Airbus A350 XWB as well as Bombar- dier’s C series. It has also been selected for space programs, including the Space X Falcon 9 Launcher and the Lockheed Martin Orion spacecraft. Constellium has fi nalized the second phase of an investment program at its Airware cast house in Issoire, France. The cast house is now fully qualifi ed by Constellium’s main customers. As with other aluminum alloys, Airware
requires standard machining operations such as contouring, skimming, pocketing and part fi nishing. These operations are performed on standard machine tools, such as vertical and horizontal machining centers, both at high speeds and standard speeds. “Airware comprises a family of harder alloys, so machining
can be different—but not signifi cantly different—than other hard aluminum alloys, said Henry. “Some of our machin- ing partners have developed special cutting tools to ensure similar effi ciency and productivity levels.” Machining Airware generates large quantities of chips and offcuts. If these ma- terials are effectively segregated, the material can be taken back into the manufacturing process.
