Aluminium producer Alcoa (NYSE:AA) said on Friday that it had helped advance space exploration with NASA's Curiosity rover on Mars.

A car-sized six-wheeled robot, Curiosity is mostly made of aluminium and incorporated into the assembly of Curiosity are high-strength precision aerospace fasteners manufactured by Alcoa Fastening Systems in California. In addition, Inconel 718 bolts and standard hexagon nuts produced at Alcoa's Newbury Park facilities and Keensert Inserts manufactured at Alcoa's Torrance plant were used in the construction of the rover.

The threaded fasteners connect the structural components and attach equipment to the vehicle and are needed to transfer high tension and high loads into the lightweight base structure. Both the Inconel 718 bolts and hexagon nuts can withstand temperatures of up to 1,200 degrees Fahrenheit (650 degrees Celsius), making them ideal for spacecraft, rocket motors and turbines.

Financial details were not disclosed.
