Aluminium Type Decision

From research into materials, 7075 aluminium has been chosen as the type of aluminium which will be used for the crane. This is due to its high strength and corrosion resistance which means it does not require any form of coating. It is also one of the easiest aluminium alloys to weld, most commonly and effectively welded using resistance welding, which is a very quick form of welding. It has a greater springback capability than most forms of aluminium which is also useful in this application where it may suffer a large amount of abuse in the situations it will be required.
