Abstract (en)
[origin: US2004234412A1] The present invention is a high strength copper alloy that is superior to mechanical properties, workability, corrosion resistance and economy. The present invention discloses high strength copper alloy characterized in that said copper alloy consists essentially of 4 to 19 mass percent of Zn, 0.5 to 2.5 mass percent of Si and the remaining mass percent of Cu, wherein said mass percent of Zn and said mass percent of Si satisfy the relationship Zn-2.5.Si=0 to 15 mass percent; mean grain size D of crystalline structure of said copper alloy distributes in 0.3 mum<=D<=3.5 mum; and 0.2% yield strength in recrystallization state of said copper alloy is higher than 250 N/mm<2>.
