High-performance copper alloy tube and preparation method thereof

Abstract

The present application discloses a high-performance copper alloy tube and a preparation method thereof. In the present application, a copper alloy tube with high strength, high processing and forming capability, excellent pressure resistance, corrosion resistance, and high-temperature softening resistance is prepared by adding Sn, Ni, and P elements to Cu, adjusting the content and proportion of each element, and introducing a high proportion of Σ3, Σ9, and Σ27 coincidence site lattice grain boundaries in combination with recrystallization treatment process. Meanwhile, elements Zr, Co, and B (optionally) are added on the basis of the above alloy components to further improve the performance of the copper alloy tube. The copper alloy tube of the present application meets the performance requirements of the high pressure-resistant and thin-walled seamless copper tube, and has broad application prospects in the field of heat exchange.
