Document Type and Number:
WIPO Patent Application WO/2023/065940
Kind Code:
A1
Abstract:
Disclosed are a Cu-Sn-P copper alloy material having a high tin content and a preparation method therefor. The copper alloy material is composed of Cu as well as 10.50-12.50wt% of Sn, 0.30-0.50wt% of P, 0.10-0.35wt% of Sc, 0.05-0.20wt% of Zr, 0.10-0.20wt% of Ni, and 0.05-0.10wt% of Zn. The preparation method comprises steps of alloy melting and casting, pre-rolling at room temperature, homogenization treatment, solid solution treatment, rolling at room temperature, intermediate annealing, tension annealing, and so on. The copper alloy material obtained by the present invention does not contain toxic elements, and produces no toxic substances during the preparation process, and thus has little harm to the human body and the environment. The prepared copper alloy material has good properties such as high strength, stress relaxation resistance, and corrosion resistance, and can be applied to manufacture various high-performance electronic components, instruments, and meters.
