International Journal of Academic Engineering Research (IJAER)   Year: 2019 | Volume: 3 | Issue: 7 | Page No.: 23-27 Mechanical Characterization of Reinforced Aluminum Alloy Zircal Hicam Laribou, Fatima Yakhlef, Lamiae Talha Abstract: The Al-Zn-Mg-Cu Aluminum alloy known as Al 7075 is a very useful material because of its mechanical properties i.e. low density, high strength, moderate ductility and toughness. Due to these properties, this alloy is mainly used for highly stressed structural parts. This material has a wide range of application such as aircraft fittings, gears and shafts, fuse parts, meter shafts and gear, missile parts, regulating valve parts, worm gears, keys and various other parts of commercial aircrafts and aerospace vehicles. The main objective of our work is to improve the mechanicals properties such as hardness, tensile strength, compressive strength of Aluminum based composite, and its relation with processing of the Alumina particulate (Al2O3) as reinforced in fly ash matrix. Aluminum 7075 alloy is chosen as matrix alloy, in which Aluminum is the base element. The work has been proposed for hardness test, compression test and tensile test. Mechanical properties as a tensile test, hardness test are conducted on Al 7075 reinforced with fly ash. These reinforcements provide comparatively high strength and hardness.
