Currently there are over 400 wrought aluminum and wrought aluminum alloys and over 200 aluminum alloys in the form of castings and ingots registered with the Aluminum Association. The melting point (or, rarely, liquefaction point) of metals is the temperature at which a substance changes state from solid to liquid at atmospheric pressure. Its principal alloying ingredients are zinc and copper, this makes it one of the highest-strength aluminum alloys that are available. Applies to embossed or patterned sheet or strip, fabricated from the corresponding Hxx temper. This heat treatment is called aging, which results in material with a T6 temper.

If 3003 alloy is held too long at temperature its grain-growth becomes excessive. Note that oil baths and salt bats are also used extensively for tempering steel tools. The amount of time at temperature for these particular alloys must only be enough to thoroughly heat either the entire work-hardened area or the complete part. On many prints, raw materials that specify aluminum are not very specific and simply state use “Alum 6061-T6” with no other designations. For example, 5052-H32.

Understanding Extruded Aluminum Alloys ... Tempers for Aluminum and Aluminum Alloy Products. Tempering is a process of heat treating, which is used to increase the toughness of iron-based alloys.Tempering is usually performed after hardening, to reduce some of the excess hardness, and is done by heating the metal to some temperature below the critical point for a certain period of time, then allowing it to cool in still air. Four basic temper designations are used for aluminum alloys. Alloy and Temper Designation Systems for Aluminum and Aluminum Alloys / 17 Table 2 Composition of wrought unalloyed aluminum and wrought aluminum alloys Grade designation I [ hum Asse- ISO No. By the end of the 1700s, aluminium oxide was known to contain a metal, but it defeated all attempts to extract it.

Applies to extruded rod, bar, shapes and tube and to drawn tube when designated as follows: Txx 510-Products that receive no further straightening after stretching. An example would be 7075-T73 where -T73 is the temper designation. The -H is always followed by two or more digits. CAUTION: Use in a well-ventilated area—vapors from heating process may be irritating to sensitive individuals. In fact, its typical strength in the T6 temper is higher than most mild steels. Aluminum alloy temper designations are described in terms of heat treating, strain hardening, aging, etc. For the most part, this generic raw material requirement is used because a part may be fabricated from plate, extruded or rolled material. Various industries have different material specification methods. In this case 2 = 1/4 hard.Aluminum/magnesium alloy ALUMINUM ASSOCIATION ALLOY TEMPER DESIGNATION SYSTEM John Weritz – The Aluminum Association Ladan Bulookbashi – The Aluminum Association Francesca Licari – The Aluminum Association February 24, 2016 .

Aluminum 6061-T6 Square Tube. Txx52 Stress-relieved by compressing. T10 Cooled from an elevated temperature shaping process. The analysis of a curious metal ornament found in the tomb of Chou-Chu, a military leader in 3 rd century China, turned out to be 85% aluminium. Thus, the elevated temperature mechanical properties re-quired to analyze and model the structural response must be measured for the specific aluminum alloy of interest. The aluminum is heat treated by carrying out a solution treatment process, in which the metal is heated to an elevated temperature followed by rapid cooling, then a precipitation hardening process (or “aging” process). This gives flexibility to the job shop, and the engineer does not want to tie down the job shop due t… Some common –T tempers … Keymark New York 1188 Cayadutta Street Fonda, NY 12068 Phone: (518) 853-3421 The Aluminum Alloy Temper and Designation System - In North America, The Aluminum Association Inc. is responsible for the allocation and registration of aluminum alloys. Applies to products which are stabilized to carry them beyond the point of maximum strength to provide control of some special characteristics. It has good mechanical properties, exhibits good weldability, and is very commonly extruded (second in popularity only to 6063). Applies to products which are artificially aged after cooling from an elevated temperature shaping process, such as casting or extrusion, and then cold worked to further improve strength. For alloys that age-soften at room temperature, the -H2 tempers have approximately the same ultimate strength as the corresponding -H3 tempers. These arrays are called GP zones, and they strengthen the aluminum considerably. Three commonly used time/temperature cycles are used for aging—one hour at 400 degrees F; five hours at 350 degrees F; and eight hours at 325 degrees F. All are equally effective. The number following this designation indicates the degree of strain-hardening remaining after the product has been partially annealed.
