What type of aluminium alloys are there?
There are hundreds of commercially available aluminium alloys controlled by an internationally agreed classification system. The choice of alloys provides a vast array of strength, corrosion resistance and workability options. Generally, alloys fall into two broad categories of either wrought alloys, which are those strengthened by cold work hardening such as rolling and the heat treatable alloys where strength and properties are achieved by heat treatments of various complexity. • What are the advantages of aluminium over steel? In a wide range of applications, aluminium holds many key advantages over steel. Its significantly higher strength to weight ratio allows more efficient use and greater spans, while its extrudeability and machineability offer greater design flexibility. It also offers a wider range of finishing options and is aesthetically pleasing in high visibility applications. In addition it is far more durable in harsh environments, is available in precise tolerances and
