High purity aluminium is a soft material with the ultimate strength of approximately 10 MPa, which limits its usability in industrial applications. Further separation into two classes, each of these categories based on the main mechanism of improving their mechanical properties, namely, through: 1. heat treatment or 2. deformation processing. 3. Yield strengths vary from 35 MPa for a low-strength aluminum to greater than 1400 MPa for very high-strength steels. United Kingdom: BS lB. Heat capacity, thermal expansion, and thermal conductivity are properties that are often critical in the practical use of solids. Aluminum alloys are a lightweight structural material. Princeton University Press. The chief limitation of aluminum is its low melting temperature (660°C), which restricts the maximum temperature at which it can be used. If so, give us a like in the sidebar. The result is a dimensionless number noted as HRA, HRB, HRC, etc., where the last letter is the respective Rockwell scale. Aluminum is a light metal, about the third of the density of steel, copper, and brass. U.S. Department of Energy, Material Science. A third digit is sometimes used to indicate a variation of the basic two-digit temper.

Aluminum 6061 has good corrosion resistance, mechanical properties, formability, weldability, and … Material properties are intensive properties, that means they are independent of the amount of mass and may vary from place to place within the system at any moment. Eberhart, Mark (2003). Aluminum is readily worked and formed using a wide variety of forming processes including deep- drawing and roll forming. Up to a limiting stress, a body will be able to recover its dimensions on removal of the load. A brief historical overview of alloys and manufacturing technologies is given in Ref. One cubic foot of steel weighs about 490 lb; a cubic foot of aluminum, only about 170 lb. The Rockwell C test is performed with a Brale penetrator (120°diamond cone) and a major load of 150kg. B 491 UNS number. Ultimate tensile strengths vary from 50 MPa for an aluminum to as high as 3000 MPa for very high-strength steels. The thermal conductivity of most liquids and solids varies with temperature. The first digit identifies the alloy group as follows: The last two digits in the 1xxx group correspond with the two digits after the decimal which indicate the minimum aluminum content. But different materials react to the application of heat differently. Mechanical properties for some aluminum alloys: 1 psi (lb/in2) = 6894.8 Pa (N/m2) ANL - Annealing, done after cold working to soften work-hardening alloys H - refers to non heat treatable alloys that are “cold worked” or “strain hardened” Eutectic melting is not eliminated by Thermal properties of materials refer to the response of materials to changes in their temperature and to the application of heat. The major load is applied, then removed while still maintaining the minor load. In general, aluminium alloys are characterized by a relatively low density (2.7 g/cm3 as compared to 7.9 g/cm3 for steel), high electrical and thermal conductivities, and a resistance to corrosion in some common environments, including the ambient atmosphere. Young’s modulus of elasticity of 2024 aluminium alloy is about 76 GPa. It is present in many intelligent solutions in established markets like building, transport, packaging, printing, and many others, in our fast moving modern society. Ashby, Michael; Hugh Shercliff; David Cebon (2007). Conversely it takes only 5% of this to remelt and recycle one tonne of aluminium.

Properties of Stainless Steel vs Aluminium Alloy. When a ductile material reaches its ultimate strength, it experiences necking where the cross-sectional area reduces locally. An aluminum alloy is a chemical composition where other elements are added to pure aluminum in order to enhance its properties, primarily to increase its strength. The mechanical property limits that correspond to each temper designation can be found by referring to an appropriate aluminum standard such as the Aluminum Association Standards and Data or ASTM B 209. In general, melting is a phase change of a substance from the solid to the liquid phase. The data is intended for comparing alloys and tempers and should not be used for design purposes. The aluminium alloys are divided into 9 families (Al1xxx to Al9xxx). It is an intensive property; therefore its value does not depend on the size of the test specimen. Ultimate tensile strength of 2024 aluminium alloy depends greatly on the temper of the material, but it is about 450 MPa. There are three different methods used to achieve the final temper of strain hardened material. I n comparison with a normal 46000 alloy, Stenal 460 has a higher tensile strength, improved fatigue properties and higher elongation. -H Strain-Hardened: Applies to wrought products which are strengthened by cold-rolling or cold-working. The strength of heat treated commercial Al alloys exceeds 550 MPa. Even though deformations can continue to increase, the stress usually decreases after the ultimate strength has been achieved. As a solid absorbs energy in the form of heat, its temperature rises and its dimensions increase. As developing countries become more involved in the aerospace industry, and with increased investment, there will be further innovation in aluminum alloys throughout the years to come. The thermal conductivity of 6061 aluminium alloy is 150 W/(m.K). Also the thermal conductivity of aluminium is very high, while its melting point is … … The minor load establishes the zero position. Aluminum has high reflectivity and can be used for decorative applications.

For example the aluminum content of 1060 is 99.60% minimum, 1100 is 99.00% minimum, 1350 is 99.50% minimum and so on. In mechanics of materials, the strength of a material is its ability to withstand an applied load without failure or plastic deformation. Alloy Designation System for Wrought Sheet Products. The stress-strain curve contains no higher stress than the ultimate strength. González-Viñas, W. & Mancini, H.L. Aluminium Alloys, Theory and Applications. Selecting the right alloy for a given application entails considerations of its tensile strength, density, ductility, formability, workability, weldability, and corrosionresistance, to name a few. Aluminum naturally generates a protective thin oxide coating which keeps the metal from making further contact with the environment. Aluminium alloy compositions are registered with The Aluminum Association. Ultimate tensile strength is often shortened to “tensile strength” or even to “the ultimate.”  If this stress is applied and maintained, fracture will result. January 1993. -O Annealed: Applies to wrought products which have been heated above the recrystallization temperature to produce the lowest tensile strength condition of the alloy. Strength of materials basically considers the relationship between the external loads applied to a material and the resulting deformation or change in material dimensions. Yield strength of 6061 aluminium alloy depends greatly on the temper of the material, but for T6 temper it is about 240 MPa. Some … –H1 Strain Hardened Only: Applies to products which are strain hardened to obtain the desired strength level without any subsequent thermal treatment. -F As Fabricated: Applies to products of rolling or forming where there is no special control over the thermal or work-hardening conditions.

Because 6061 aluminium alloy is easy to extrude, it can provide a variety of product forms such as sheet, strip, plate, rod, rod, forgings, tubes, pipes, wires, extruded parts and structural shapes. The values indicate maximum limits unless shown as a range or a minimum. In addition, advantages are … alloys. This allows the metal to achieve its highest heat-treated strength level. January 1993. Aluminum has high reflectivity and can be used for decorative applications. Prior to the yield point, the material will deform elastically and will return to its original shape when the applied stress is removed. The alloy has a lower iron content, is alloyed with strontium and the manganese content is balanced against the iron content compared to a standard alloy. The chief advantage of Rockwell hardness is its ability to display hardness values directly. We hope, this article, Properties of Aluminium Alloys, helps you. The last two digits of the other groups are sequential numbers issued by the Aluminum Association to ensure each alloy is uniquely identified. Melting ranges shown apply to wrought products of 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). 6. The alloys are conveniently divided into eight groups based on their principal alloying element. Coefficient to be multiplied by homogenization.
