What is the threat of competing materials forcing a decline in the aluminum/alumina markets?
Though modern science continually discovers and develops new materials and/or new applications for existing materials, there is nothing on the horizon that would have a material impact in the indefinite future on the anticipated growth in aluminum demand. Though there is a lot of talk about composite materials increasing their share of the aviation market this is a small, specialist part of the aluminum market. By far the largest share of the transportation market is taken up by motor vehicles and here the amount of the metal in each vehicle is rising as well as the overall numbers of vehicles produced Worldwide.
