Alternate names and designations include AlSiMg(A) and 3.3210. The alloy and its various tempers are covered by the following standards: [2] ASTM B 221: Standard Specification for Aluminum and Aluminum-Alloy Extruded Bars, Rods, Wire, Profiles, and Tubes; EN 573-3: Aluminium and aluminium alloys. Chemical composition and form of wrought products.
The temper designation follows the cast or wrought designation number with a dash, a letter, and potentially a one to three digit number, e.g. 6061-T6. The definitions for the tempers are: [5] [6]-F : As fabricated-H : Strain hardened (cold worked) with or without thermal treatment -H1 : Strain hardened without thermal treatment
It can also be forged or rolled, but as a wrought alloy it is not used in casting. It is commonly heat treated to produce tempers with a higher strength at the expense of ductility. [1] Alternate names and designations include AlSiMg and A96005. The alloy and its various tempers are covered by the following standards: [2]
Alternate names and designations include AlMgSi, 3.3206, and A96060. The alloy and its various tempers are covered by the following standards: [2] ASTM B 221: Standard Specification for Aluminum and Aluminum-Alloy Extruded Bars, Rods, Wire, Profiles, and Tubes; EN 573-3: Aluminium and aluminium alloys.

It cannot be work hardened, but is commonly heat treated to produce tempers with a higher strength but lower ductility. [1] Alternate names and designations include AlSi1MgMn, 3.2315, H30, and A96082. The alloy and its various tempers are covered by the following standards: [2] EN 485-2: Aluminium and aluminium alloys. Sheet, strip and plate.
The process, called "normalize and temper", is used frequently on steels such as 1045 carbon steel, or most other steels containing 0.35 to 0.55% carbon. These steels are usually tempered after normalizing, to increase the toughness and relieve internal stresses.
Alternate designations include 3.0526 and A93004. 3004 aluminium and its various tempers are discussed in the following standards: [3] ASTM B 209: Standard Specification for Aluminium and Aluminium-Alloy Sheet and Plate; ASTM B 221: Standard Specification for Aluminium and Aluminium-Alloy Extruded Bars, Rods, Wire, Profiles, and Tubes
The retrogression and reage (RRA) temper is a multistage heat treatment temper. Starting with a sheet in the T6 temper, it involves overaging past peak hardness (T6 temper) to near the T7 temper. A subsequent reaging at 120 °C for 24 hours returns the hardness and strength to or very nearly to T6 temper levels. [10]
