Someone’s been given access to a market report I wrote 10 years ago:
The Chicken and Egg Problem With Energy Metals: Scandium as a Case Study
That’s what I called it, the chicken and egg problem.
Around 10 per cent of the weight of an airplane is accounted for by the rivets used to maintain its structure. An Airbus A380 reportedly has an empty weight of 610,000 pounds. It is believed that using Al-Sc alloy in airplanes can reduce the overall aircraft weight by 10 to 15%, so the weight reduction is substantial and would more than pay for the cost of scandium over the life of the aircraft in higher operating efficiency. As fuel is the primary cost for airlines, scandium use to lower aircraft weight should be of particular interest as it can help mitigate the effects of higher fuel prices. Clearly Airbus has seen the light.
And that’s striaght from that study.
