Claim 0:
1. A Nb and Al-containing titanium-copper alloy strip, characterized in that the weight percentage composition of the titanium-copper alloy strip comprises:
2.0-4.5 wt % Ti, 0.005-0.40 wt % Nb, and 0.01-0.50 wt % Al, the balance being Cu and unavoidable impurities; and
further characterized in that in the titanium-copper alloy strip, the number of Nb and Al-containing intermetallic compound particles with a particle size of 50-500 nm is not less than 1×105/mm2, and the number of Nb and Al-containing intermetallic compound particles with a particle size greater than 1 μm is not more than 1 ×103/mm2; and
the titanium-copper alloy strip has a ratio of the bending radius parallel to the rolling direction to the thickness of the strip R1/T≤0.5, and a ratio of the bending radius perpendicular to the rolling direction to the thickness of the strip R2/T≤1.0; and/or the titanium-copper alloy strip has a yield strength of greater than 900 MPa and an electrical conductivity of 10-20% International Annealed Copper Standard.
