Aluminium alloys have a wide variety of applications in the industrial sector due to some unique characteristics like lightweight, high strength to weight ratio, corrosion resistance, good electrical conductivity, recyclability, ductility, and formability, etc. Due to this unique combination of properties, the applications of aluminium alloys continue to increase. The tribological behavior and impact strength were studied in this research work by conducting the wear and impact tests, varying the composition of two major alloying elements, Magnesium (Mg) and Zinc (Zn) of Al7068 aluminium alloy. The specimens were prepared as per ASTM standards for wear and impact tests, four compositions each for Mg% varying b/w (2.2 to 3%), and Zn % varying b/w (7.3 to 8.3%). The results of the wear test on the alloy Al7068 shows that the specimens with 3% Mg and 7.6% Zn compositions gives least wear rate at loads 2 kg and 3 kg respectively whereas the specimens with compositions of 2.75% Mg and 7.3% Zn give highest wear rate at a low load of 1 kg. The impact test results indicate that specimens with compositions of 2.2% Mg and 7.6% Zn of the alloy Al7068 give the highest impact strength which in turn improves its performance.

“…One of the major metal alloys that are commonly used in different industrial applications is Al alloys, due to their properties, for instance, formability, strength-to-weight ratio, corrosion resistance, and weldability [1][2][3][4]. Different types of Al alloys are widely used in numerous industrial applications, such as aerospace, automotive, construction, marine fabrication industries, electrical engineering, and biomedical applications [5][6][7][8][9][10][11]. Most Al alloys have superior mechanical and electrical properties compared with Al (1050) alloy properties.…”

Aluminum alloys use is so profound in many applications such as transportation, construction, energy, defense applications, automotive, aerospace, to name a few. Therefore, investigating the mechanical and electrical properties of the different types for aluminum alloys is vital. The Al–Mg alloy is widely used in the automotive industry because of its optimal properties, for example, corrosion resistance, weldability, and strength-to-weight ratio. This study aims to investigate and model the effect of changing the magnesium percentage content on the hardness and electrical conductivity of Al–Mg alloy with a detailed statistical analysis to validate the results. The microstructure at each Mg percentile content is demonstrated using a scanning electron microscope (SEM) and an optical microscope for validating the Mg content after solidification and tracking the grain size evolutions at different Mg percentiles. Vickers hardness testing is applied for hardness evaluation at each experimental condition. The electrical conductivity is tested using a PCE 20COM electric conductive non-destructive test (NDT). Prediction models are constructed to estimate the hardness and electrical conductivity as a function of Mg percentile by using a nonlinear optimizer. The results indicated that the hardness is significantly increased with increasing the Mg content by three times when comparing 0 Mg wt.% and 5 mg wt.%. In contrast, a 48% reduction in the electrical conductivity is found when Mg wt.% is increased to 5 and a notable decrease in the grain size is observed when the Mg content is increased.
