It is important to take note of these thermal designations when subjecting the aluminum alloy to processes that create enough heat to alter the heat treatment or strain hardening.
X, 3XX. X, 4XX. X and 7XX. X series of aluminum alloys are heat treatable. The exception to this is some of the 4XXX series aluminum alloys are unresponsive to heat treatment.

The agreed upon numbering system divides the alloys into distinct groups based upon the primary alloying agent. Before anything else, the most important factor is whether the aluminum alloy is wrought or cast.
First off, wrought aluminum alloys follow a four-digit identification system, where the first number indicates what the main alloying element is. We normally refer to these alloys according to which series they belong to, such as the series or the series. In total, there are 8 different wrought aluminum series, 1xxx to 8xxx. So as an example, for aluminum alloy , the 2 indicates it is from the series, which has copper as the principle alloying agent, and the 1 indicates it is the first recognized modification of the original alloy.
So, for alloy , there is Besides the first two series, the others by main alloying agent are manganese , silicon , magnesium , , magnesium AND silicon , zinc , and all other agents. In contrast to the wrought aluminum designation system, the one for cast alloys is based on a 3-digit plus decimal designation xxx. Again, the first digit refers to what the principal alloying element is.
The second and third digits again indicate the specific alloy in the series, while the number that comes after the decimal point refers to either a casting. Furthermore, if there is a capital letter that comes before the number, this means there has been a modification to the alloy.
Not every aluminum alloy series is heat treatable. The 1xxx, 3xxx, and 5xxx series are generally not heat treatable, while the 4xxx series has some alloys that are heat treatable and others that are not. To indicate what kind of heat treatment has been done to the alloys, letters are appended to the end. F is used to indicate as fabricated, meaning no special heat treatment has been applied. O means the alloy has been annealed, normally to improve ductility and dimensional stability.
H is strain hardened, and the H is always followed by two digits that provide more information about the treatment. W means the alloy has been solution heat treated, while T indicates it has been thermally treated. The T is also followed by one or more digits that offer more information. So those are the basics when it comes to the aluminum numbering system.

Group number — 1. Nominal composition — C-Mn-Si. Typical product form — Plate. It was deleted from ASME in This grade is commercially pure aluminum.
It is soft and ductile and has excellent workability. It is ideal for applications involving intricate forming because it work hardens more slowly than other alloys. It is the most weldable of aluminum alloys , by any method. It is non heat-treatable. See Also : Cell Phone Show details. Fortunately, Tyre Leader is here to help you.
