Aluminum Association designations and product standards information are used throughout all facets of aluminum commerce, as well as in other organizations’ codes and standards. Aluminum alloy and temper designations, chemical composition limits and registered properties in North America, all originate from the above system of ANSI and AA standards. These standards are also the basis for several international agreements for the worldwide producer registration of wrought alloys, unalloyed aluminum, and aluminum hardeners (aluminum alloy materials and grain refiners).
Japanese Industrial Standards (JIS) (日本工業規格 Nippon Kōgyō Kikaku?)specifies the standards used for industrial activities in Japan. The standardization process is coordinated by Japanese Industrial Standards Committee and published through Japanese Standards Association.
Aluminium for extrusion is mostly alloys with the following serial numbers:
1000 series – Al
6000 series – Al + Mg + Si
7000 series – Al + Zn + Mg
The 6000 series has good extrudability and is often the optimal choice. Termed “soft alloys” due to their ability to be easily weld, these alloys have medium to high strength and offer good resistance to corrosion, even in marine environments. The bulk of the extruded material for load bearing constructions is made from these qualities. They are used for load bearing constructions both on land and at sea.
