Abstract
The present invention discloses a super-strong high-conductivity copper alloy and applications thereof as the contact wire materials of high speed railways allowing a speed of over 400 km per hour. The copper alloy comprises niobium, chromium, zirconium, titanium and remaining copper; the copper alloy exists in the form of long bar or wire, wherein niobium is distributed in the copper matrix in the form of nanofibers and solid solution atoms, chromium is distributed around the niobium fibers and the copper matrix in the form of nano-particles and solid solution atoms, zirconium is distributed around the niobium fibers and in the copper matrix in the form of copper-zirconium compound nano-particles and solid solution atoms; titanium is distributed in the copper matrix in the form of copper-titanium GP zone and solid solution atoms; the total amount of niobium, chromium and zirconium solid solution atoms contained in the copper alloy is less than 0.2%.
