Engineering Toolbox When increased toughness is desired at the expense of strength, higher tempering temperatures, from 370 to 540 °C (698 to 1,004 °F), are used. -T3: Solution heat treated and then cold worked. This is called the T4 temper. -T851: Solution heat treated, stress-relieved by stretching and artificially aged. The tensile strength of this temper is greater than the T73 temper, but less than the T76 temper. Aluminum Tempers. Applies to 2024-T3 artificially aged to T-81. 6063 is used for architectural fabrication, window and door frames, pipe and tubing, and aluminium furniture. Engineering Forum Temper Types. Melting temperatures of common metals and alloys. After solution heat treatment, after natural aging and cold working temper, it is suitable for products whose strength is improved by cold working. lXXX     997. -T61: Solution heat treated and then artificially aged. It is suitable for products that are cold worked or straightened or leveled to improve strength after solution heat treatment. -T87: Solution -heat treated, cold worked by a thickness reduction of 10 percent and then artificially aged. This temper code only indicates that the product is in the natural aging stage. T8 is solution heat treated, cold worked, and then artificially aged. It is suitable for products whose strength is increased through work hardening. Address: No.6, Changchun Road, High-tech district, Zhengzhou City. What is the exact process to temper extruded 6063 aluminum to T66? Low temperature tempering is also applied to components, which undergo surface hardening treatments and case hardening treatments, like carburising, cyaniding, or carbonitriding. die forgings which are stress-relieved by restriking cold in the finish die. But aluminum melts at only about 1,260 degrees, so it loses about half of its strength by the time it reaches 600 degrees. Email: The most common tempers for 6082 aluminium are: 6063 O. Un-heat treated / Soft. ; Aluminum2XXX    Copper 2XX..X Copper3XXX    Manganese 3XX.X Silicon with added copper and/or magnesium4XXX    Silicon 4XX.X Silicon5XXX    Magnesium 5XX.X Magnesium6XXX    Magnesium and Silicon6XX.X   6063 is highly weldable, using tungsten inert gas welding. -T6: Solution heat treated and then artificially aged. -T52: Cooled from an elevated temperature shaping process, stress-relieved by compressing and then artificially aged. Der Begriff Tempern beschreibt allgemein das Erhitzen eines Materials über einen längeren Zeitraum. Understanding aluminum temper designations is vital to picking the correct material for your next project. The cool thing about this method is that it gives you a lot of options for heating up the aluminum, based on what you have. , Engineering Metals and Materials Table of Contents, GD&T Training Geometric Dimensioning Tolerancing. Aging refers to the change in material properties resultant of exposure to environmental conditions (such as rusting).
