This present study is concerned with the investigation of mechanical properties of copper alloy castings produced by investment casting process using Acrylonitrile Butadiene Styrene (ABS) as the pattern material and the Plaster of Paris as the mould material. The studies on the process parameters and the mechanical properties of the copper alloy casting have gained significance. The aim of this research is to investigate the effect of burning temperature, firing time and pouring temperature on surface hardness and dimensional accuracy of the end casts. The sample is using copper alloy as the material which is the combination of elements like copper and zinc. This research used two levels of three parameters which are burning temperature, firing time and pouring temperature of the alloy to investigate their effects on the surface hardness and imensional accuracy of the end casts. Experiments were conducted as per Full Factorial with Design Expert software. The experimental analysis revealed that the high burning temperature, high firing time and high pouring temperature of the copper alloy can influence the mechanical properties of copper alloy casting due to P-value in ANOVA result for hardness. The results also showed that the high firing time and pouring temperature can influence the dimensional accuracy of the samples. Furthermore, the study emphasized on the improvement of mechanical properties of copper alloy casting which can be achieved by optimizing the correlated processing parameters such as its burning temperature, firing time and pouring temperature of the alloy.
