Effect Of Zinc Addition on the Microstructure and Mechanical Properties of 6063 Aluminum 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 150 mm * 15 mm. The 6063 aluminium – Zinc alloy was machined to standard tensile dimensions of G.D 5 mm, G.L 40 mm, external diameter 8 mm, two opposite external length of 30 mm; hardness dimensions of 20 mm * 20 mm * 20 mm; and impact dimensions of length 60 mm, diameter 10 mm, notch at 30mm with 3mm depth. The aluminium- zinc alloys were heat treated to 300 oC and 400 oC; and held at a soaking time of 2 hours, allowed to cool in the furnace and another series of aluminium - zinc alloy was not heat treated. The specimens were destructively tested and the homogenized 400 oC aluminium-zinc alloy possessed the greatest strength of 237 MPa, a hardness value of 113 HV, a maximum percentage elongation of 22.5% and a maximum impact energy of 70.5 J. Thus, the alloy can be used for applications requiring high strength and hardness coupled with low ductility.
