Abstract

Aluminum drill pipes have low density, high specific strength and good stress corrosion resistance, possessing a huge application potential in the oil drilling. The 1953 alloy belongs to the Al–Zn–Mg–Cu alloy, and it is one of the most promising aluminum alloy materials for petroleum drill pipe. In this paper, the 1953 aluminum alloy were studied by hardness tests, conductivity tests, tensile tests, optical microscope and scanning electron microscopy. The results show that there are a large number of AlZnMgCu phases and a small amount of Fe and Si impurity phases after extrusion. After the solution treatment, the AlZnMgCu phases have been dissolved, and the residual phases in the alloy are mainly impurity phases with Fe and Si. The comprehensive performance is excellent after solution treatment at 440 °C/1 h + 470 °C/1 h and aging treatment at 120 °C/24 h. The hardness, electrical conductivity, yield strength, tensile strength and elongation can reach 191.2 HV, 18.9 MS/m, 578 MPa, 620 MPa, and 11.2%, respectively.
