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. Note, careful consideration of alloy microstructures may The main processing methods include hot working, cold working, solution heat treatment, aging treatment, annealing treatment, etc. The formed parts can be subsequently heat treated to higher strength. Temper designations of wrought aluminum alloys consist of suffixes to the numeric alloy designations. aluminum alloy temper designations, the typical mechanical properties of representative wrought and cast aluminum alloys are presented in Tables 1 and 2, respectively. Applies to products for which the rate of cooling from an elevated temperature shaping process, such as casting or extrusion, is such that their strength is increased by room temperature aging. The versatility of aluminium makes it the most widely used metal after steel. But it is important to recognize and understand what the letters and numbers mean. The number following this designation indicates the degree of strain-hardening remaining after the product has been strain-hardened a specific amount and then stabilized. 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. T62 Solution heat-treated from the 0 or F temper to demonstrate response to heat-treatment and artificially aged. How it was produced remains a mystery. 1-0 Annealed, recrystallized (wrought products only): Applies to (the softest temper of wrought products.

H-3 Strain-hardened and then stabilized: Applies to products which are strain-hardened and then stabilized by a low temperature heating to slightly lower their strength and increase ductility. Various industries have different material specification methods. 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. T3 Solution heat-treated and then cold worked. It is not easy, at a glance, to make sense of temper designations. For example, 5052-H32.

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. 7075 is the other “aircraft grade” aluminum. T7 Solution heat-treated and then stabilized. For alloys that age-soften at room temperature, the -H2 tempers have approximately the same ultimate strength as the corresponding -H3 tempers. 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. Related Topics . This heat treatment is called aging, which results in material with a T6 temper. Its principal alloying ingredients are zinc and copper, this makes it one of the highest-strength aluminum alloys that are available. 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.

Aluminium alloy 6061 is one of the most extensively used of the 6000 series aluminium alloys. For other alloys, the -H2 tempers have approximately the same ultimate strength as the corresponding -H1 tempers and slightly higher elongations. These arrays are called GP zones, and they strengthen the aluminum considerably. -H Strain-hardened (wrought products only): Applies to products which have their strength increased by strain-hardening with or without supplementary thermal treatments to produce partial softening. T62 Solution heat-treated from the 0 or F temper to demonstrate response to heat-treatment and artificially aged.

Applies to products which are stabilized to carry them beyond the point of maximum strength to provide control of some special characteristics. T5 Cooled from an elevated temperature shaping process and then artificially aged. The T8 and T9 tempers offer better chipping characteristics over the T6 temper. T42 Solution heat-treated from the 0 or F temper to demonstrate response to heat-treatment, and naturally aged to a substantially stable condition. In case of skin irritation, immediately wash skin with soap and water; for contact with eyes, immediately flush with water. 6061 is commonly used for structural components, screw machine parts, frames, brackets, jigs, fixtures, base ... Understanding Extruded Aluminum Alloys ... Tempers for Aluminum and Aluminum Alloy Products. 5052= Aluminum/magnesium alloy, H3 = strain hardened and stabilized by low temperature heating. 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. artificially aged and then cold worked. Note that oil baths and salt bats are also used extensively for tempering steel tools. When it comes to choosing the right grade of aluminum for a particular application, it’s best … Assigned additional digits for T7 temper per ANSI 35.1/H35.1(M)-2009. For example, in 3003-H14, 3003 denotes the alloy and “H14” denotes the temper, or degree of hardness. T10 Cooled from an elevated temperature shaping process. Applies to products which are stress-relieved by compressing after solution heat-treatment, or cooling from an elevated temperature shaping process to produce a permanent set of 1 to 5 percent. For the most part, this generic raw material requirement is used because a part may be fabricated from plate, extruded or rolled material. T2 Annealed (cast products only). We are looking for a chart that describes what the Webster reading should be for the following: 6061 T6 6005 T5 6066 T5 6063 T6 6064 T4. The second digit indicates strain hardening to the following degrees: The following three digit -H temper designations have been assigned for wrought products in all alloys: -H111, -H311 and -H321 apply to products which are strain-hardened less than the amount required for -H11, -H31 and -H32, respectively. Rod, bar, shapes, extruded tube: 1 to 3% permanent set. Example: Purple = 275°C / 545°F These products receive no further straightening after stretching. Aluminum is usually named in 4 numerical digits and follows by a temper designation. 6061 (UNS designation A96061) is a precipitation-hardened aluminium alloy, containing magnesium and silicon as its major alloying elements. In North America, The Aluminum Association Inc. is responsible for the allocation and registration of aluminum alloys. On many prints, raw materials that specify aluminum are not very specific and simply state use “Alum 6061-T6” with no other designations. T9 Solution heat-treated, artificially aged, and then cold worked. Txx511-Products that may receive minor straightening after stretching to comply with standard tolerances. Temper designations T42 and T62 may also be applied to wrought products heat-treated from any temper by the user when such heat-treatment results in the mechanical properties applicable to these tempers.
