Aluminium Bronze (Al-bronze) part of the Copper alloy family. It is a structural, non-heat treatable alloy offering unmatched properties of high strength, hardness and wear resistance. Al-bronze is extensively used in automobiles, aeronautical, marine, and general engineering applications. In this study copper and bronze with 10% aluminium are prepared by die-casting process and the comparative study has been made. The density of copper and Al-bronze was determined using water displacement method (Archimedes Principle). The average density of copper and Al-Bronze are reported as 8.6975±0.0695 g/cc and 7.610±0.0015g/cc respectively. The microstructure analysis of copper and Al-bronze was carried out using the optical metallurgical microscope. The micrograph (surface topography) of copper and Al-bronze was revealed as equiaxed grains and martensitic structure. The average value of micro-Vickers’s hardness of copper and Al-bronze are found to be 619.80±27.51MPa and 1374±97.13MPa. Tensile/ compression test was performed at room temperature using the BISS, 25 kN tensile testing machine. The ultimate tensile strength (UTS) of pure copper is 257±28.33MPa and Al-bronze is 550.95±16.6MPa. Similarly, the compression strength was also measured using the same testing machine and the ultimate compression strength (UCS) recorded for pure copper is 324.46±37.5MPa and Al-bronze is 384±21.31MPa. The tribological properties of copper and Al-bronze were investigated using the Pin-on disc wear testing machine for different speeds and different load conditions. The results are encouraging which calls for wider applications and testing.
