Disclosed is a copper-niobium alloy for a medical biopsy puncture needle. A needle core and/or needle tube of the puncture needle are/is made of the copper-niobium alloy. The copper-chromium alloy includes the following components by mass: 5≤Nb≤15 and the balance of Cu. A copper alloy with designed components is obtained by combining a diamagnetic material Cu with paramagnetic Nb, and compared with existing medical stainless steel and titanium alloy, the copper alloy has greatly reduced magnetic susceptibility, and specifically, the artifact area and volume are also significantly reduced. In addition, the blank of use of the copper alloy in medical biopsy paracentesis is filled.
A copper-niobium alloy for a medical biopsy puncture needle, wherein a needle core and/or needle tube of the puncture needle are/is made of the copper-niobium alloy, and the copper-niobium alloy consists of the following components by mass:
