| ＜Aluminum Alloys＞ Aluminum with a purity of 99.00% or higher is classified as pure aluminum, while aluminum alloys are those in which various elements are added to improve properties such as strength. Aluminum alloys are broadly divided into wrought alloys, which are processed into sheet, foil, extrusions, tubing, bar, and forgings according to the required properties for each application, and casting alloys, which are used for castings and die-cast products. Furthermore, each can be classified as either non-heat-treatable alloys or heat-treatable alloys. Non-heat-treatable alloys obtain their specified strength mainly through cold working such as rolling, while heat-treatable alloys achieve their strength through heat treatments such as quenching and tempering. |
