Beschreibung
Zusammenfassung:	The invention discloses an alloy material of copper, nickel, silicon and bronze and a preparation method thereof. The alloy material comprises the following substances in percent by weight: 1.6% to 2.2% of nickel, 0.4% to 0.8% of silicon, 0.008% of rare earth alloy and 96.002% to 97.002% of copper. The alloy material of copper, nickel, silicon and bronze is prepared by the processes of proportioning, melting, casting, sawing, extruding, drawing, straightening, inspecting and packing into a warehouse, enhances the stress corrosion resistant capability, and has the main performance change of reducing a hardness value and the grain size.
