An aluminum alloy designated 7085 developed by Alcoa is getting a foothold in tough aircraft and military applications.
The first application of 7085 was for large die forgings on the Airbus A380 wing spars. Higher zinc along with reduced copper and magnesium content give the aluminum alloy excellent strength and high fracture toughness. It’s used in the Boeing Dreamliner for wing spars and engine pylons. It’s also being evaluated for thick structural parts, such as blast shields, on military vehicles.
Engineers shifted from titanium to 7085 for large forgings that form the center section of the bulkhead of the multinational Joint Strike Fighter’s F-35B variant for the US Marines and Royal Navy. Reason: To save weight. Titanium is 60 percent more dense than the aluminum alloy.
Two new technologies from Stratasys, created in partnership with Boeing, Ford, and Siemens, will bring accurate, repeatable manufacturing of very large thermoplastic end products, and much bigger composite parts, onto the factory floor for industries including automotive and aerospace.
These new 3D-printing technologies and printers include some that are truly boundary-breaking: a sophisticated new sub-$10,000, 10-plus materials bioprinter, the first industrial-strength silicone 3D-printing service, and a clever twist on 3D printing and thermoforming for making high-quality realistic models.
