Effect Of Zinc Addition on The Microstructure and Mechanical Properties of AA6063 Aluminium Alloy
Year: 2025
Type: article
Abstract: This research work entails addition of Zinc metal to the 6063 aluminium alloy series. The Zinc addition ranged from a percentage of 1% - 5% at an interval of 0.5%. Charge calculations were made and the aluminium alloy and Zinc were melted in a crucible furnace. Permanent mold casting was utilized with dimension of 150mm * 15mm. The 6063 aluminium – Zinc alloy were machined to standard tensile dimensions of G.D 5mm, G.L 40mm, external diameter 8mm, two opposite external length of 30mm; hardness dimensions of 20mm * 20mm * 20mm;and impact dimensions of length 60mm, diameter 10mm, notch at 30mm with 3mm depth. The aluminium- zinc alloys were heat treated to 300oC and 400oC; and held at a soaking time of 2 hours, allowed to cool in the furnace and another series of aluminium - zinc alloy were not heat treated. The specimens were destructively tested and the homogenized 400oC aluminium-zinc alloy possessed the greatest strength of 237MPa, a hardness value of 113HV, a maximum percentage elongation of 22.5% and a maximum impact energy of 70.5J. Thus, the alloy can be used for applications requiring high strength and hardness coupled with low ductility.
