-- Ni-Al-Bronze alloy with Improved strength and elongation and use thereof

摘要

The present invention relates to a copper alloy comprising 7 to 11 parts by weight of aluminum, 3 to 6 parts by weight of nickel; And 0.005 to 0.07 part by weight of zirconium. The nickel-aluminum-copper alloy has improved strength and elongation at the same time. According to the nickel-aluminum-copper alloy of the present invention, there is an advantage that a seawater product having high strength and high elongation characteristics can be efficiently produced.
