But that seems rather unlikely. Aluminum is still lightweight, technically advanced in terms of forming and alloying, and it relatively low cost, especially when compared to titanium and composites.</p></div> <div class="og_rss_groups"></div><p><a href="http://machinedesign.com/materials/basics-aerospace-materials-aluminum-and-composites" target="_blank">read more</a></p> http://machinedesign.com/materials/basics-aerospace-materials-aluminum-and-composites#comments Materials Thu, 19 Jun 2014 14:40:00 +0000 38351 at http://machinedesign.com
