Metallic materials have a historic and enduring importance in our society. They have strengthened the trail of human civilization with load-bearing applications that may be used under the harsh environmental conditions. Metals have the greatest potential for unlimited recycling. The elemental nature of metals means that they can virtually be reused and recycled indefinitely without loss of their properties. The ability to recycle metals offers opportunities to conserve resources, reduce energy usage and minimise waste disposal, all of which represent important contributions to the sustainable development.
