Abstract: PURPOSE: A copper alloy composition is provided to increase commodity value and extend life cycle of various accessories or decorative building interior materials by preventing discoloration according to oxidation corrosion of the surface of copper alloy used as imitation gold. CONSTITUTION: The copper alloy composition comprises 0.4 to 0.7 wt.% of Zn, 4 to 6 wt.% of Al, 0.1 to 0.3 wt.% of Fe, 0.2 to 0.5 wt.% of Si, 0.3 to 1.2 wt.% of In, 0.3 to 0.7 wt.% of Ti, and a balance of Cu, wherein it is not preferable that contents of Fe and Si are deviated from the above respective ranges since castability is deteriorated due to viscosity change if their contents exceed the ranges, formability of the alloy is deteriorated since ductility is reduced due to formation of In oxide in the alloy if excessive amount of In is added to the alloy, it is inevitably difficult to escape discoloration of the surface of the alloy during long term use of the alloy in the air since formation of oxide film (Al2O3) is limited although Al added to the alloy in the amount of 4 to 6 wt.% greatly contributes to increase of alloy strength, and 0.3 to 0.7 wt.% of Ti is added to the alloy to prevent discoloration of the surface of the alloy since Ti is expensive, and manufacturing cost is increased if content of Ti exceeds 0.7 wt.%.
