In this work, the tensile and hardness properties were investigated on the several metallic materials such as aluminium, copper and galvanize steel. The main objective in this research is to study the relationship between the tensile and hardness properties on several metallic materials with the help of microstructures observation and regression analysis for interpretation of the data. Besides, the measurement uncertainty also conducted to determine the validation of the data. INSTRON 5965 and Vickers hardness machine were used to determine the correlation between the hardness and strength of the materials.Besides, iSolution software with the optical microscope also was used in observing the microstructure. It was found that the actual correlation between hardness and strength for aluminium, copper and galvanize steel are in the range 2.94 - 2.95 for aluminium, 2.76 - 2.77 for copper and lastly 2.78 – 3.13 for galvanize steel. However, the measurement uncertainty help to validate the correlation between hardness and strength. From the measurement uncertainty calculation, the value for yield strength and ultimate tensile strength for copper, aluminium and galvanize steel are 2.69 and 2.75; 7.60 and 7.80; 17.05 and 17.13 respectively. Aluminium had the fine grain compared to galvanized steel. However, the strength of aluminium is lower than galvanize steel and copper.
