Aluminium alloys are widely used in engineering structures and components where light weight or corrosion resistance is required. [1] Alloys composed mostly of aluminium have been very important in aerospace manufacturing since the introduction of metal-skinned aircraft. Aluminium–magnesium alloys are both lighter than other aluminium alloys ...
Property [2] Value Young's modulus: 69 GPa Elongation at break: 5.1% Fatigue strength: 49 MPa U.T.S. 130 MPa Yield strength: 100 MPa Latent Heat of Fusion: 400 J/g Specific Heat Capacity: 900 J/kg-K Thermal Conductivity: 230 W/m-K
7068 alloy is a 7000 series aluminium-zinc alloy registered with the US Aluminium Association and produced to AMS 4331 (chemical composition and mechanical properties) and AMS 2772 (heat treatment). 7068 alloy ‘A’ and ‘B’ tensile data and fatigue properties have been ratified for inclusion in MIL Handbook 5 / MMPDS.
It is one of the most commonly used aluminium alloys for highly stressed structural applications and has been extensively used in aircraft structural parts. [ 2 ] 7075 aluminium alloy's composition roughly includes 5.6–6.1% zinc , 2.1–2.5% magnesium , 1.2–1.6% copper , and less than a half percent of silicon, iron, manganese, titanium ...
6063 is the most common alloy used for aluminium extrusion. It allows complex shapes to be formed with very smooth surfaces fit for anodizing and is popular for visible architectural applications such as window frames, door frames, roofs, and sign frames. [3] Applications requiring higher strength typically use 6061 or 6082 instead.
Unhardened 5086 has a yield strength of 120 MPa (17 ksi) and ultimate tensile strength of 260 MPa (38 ksi) from −28 to 100 °C (−18 to 212 °F). At cryogenic temperatures it is slightly stronger: at −196 °C (−321 °F), yield of 130 MPa (19 ksi) and ultimate tensile strength of 380 MPa (55 ksi); above 100 °C (212 °F) its strength is reduced.
Aluminium 7050 alloy is a heat treatable alloy. It has high toughness, high strength. It has high stress corrosion cracking resistance. [1] It has electric conductivity of value having 40 percent of copper. [2] 7050 aluminium is known as a commercial aerospace alloy. [3]
It has the highest strength of the non-heat treatable alloys with an Ultimate Tensile Strength of 317 MPa or 46000 psi and a Tensile Yield Strength of 228 MPa or 33000 psi. It is not recommended for use in temperatures in excess of 65 °C. [2] Alloy 5083 is also commonly used in cryogenic applications due to it being able to be cooled to -195 ...
