| Abstract: | This paper studies the preparation and influence of heat treatment on the structure and properties of C70250 copper alloy of high strength Cu-Ni-Si alloy.The results show:the C70250 alloy has good solution treatment soften effect and good aging treatment to enhance strength;the best aging temperature of the alloy is 390~410 ℃,keeping this temperature for 1~2 hours,the alloy can get to the best stength;the Rm attain 728.8 MPa;the conduct electricity rate can attain 36.37%.The conduct electricity rate reduces with the strength increasing,but it can get the best match of strength and conduct electricity by adjusting the aging treatment process. |
