Temper. The system for designating material condition, whether the product form is strip, rod, or wine, is defined in ASTM Recommended Practice B601 (1). The ASTM system uses an alpha-numeric code for each of the standard temper designations. This system replaces the historical terminology of half hard, hard, spring, etc. Table 3 summarizes temper designations.

AA. Aluminum Association produced a four-digit system for wrought aluminum alloys and a three-digit system for cast alloys. Examples are alloys 6010 (wrought) and 356 (cast). A temper designation is also required. It follows the alloy designation and indicates the heat-treated or mechanically worked condition of the alloy such as 6010-T6. The T6 suffix indicates the alloy is in the precipitation hardened condition for optimum strength. 

Aluminum alloys consist of several families, used for low density (lightness), corrosion resistance and high strength-to-weight ratio. Aluminum alloy descriptions comprise the alloy designation plus the thermal-mechanical condition (temper designation), such as 6061-T6. See Figure 4-13. 

Common temper designations in the heat treatable alloys are as follows ... 

Hardness. Following exposure to elevated temperature, the high-strength Ixxx alloys (7075,7050, etc.) are in an unstable temper designated as W. For example, either a solution heat treatment or FSW, where the weld nugget experiences temperatures sufficient to dissolve the strengthening precipitates, is necessary. In the W temper, these alloys spontaneously age at room temperature, continuing to harden essen-...
