Abstract

The invention discloses a machining process of high-strength and heat-resisting aluminum alloy wires. The process comprises performing solid dissolution on a high-strength and heat-resisting aluminum alloy bar at 480-540 DEG C for 1-10 h, performing rolling treatment on the solid-dissolved high-strength and heat-resisting aluminum alloy bar at a deformation degree of 31-83% into alloy rods with a diameter of 6-10 mm, and then performing aging treatment on the rolled alloy rods at 130-220 DEG C for 2-20 h; drawing the alloy rod in a drawing machine into the high-strength and heat-resisting aluminum alloy wires with a diameter of 2-5 mm; performing aging treatment and nondestructive detection. The aluminum alloy wires machined through the machining process of the high-strength and heat-resisting aluminum alloy wires achieve a tensile strength of 242 MPa, an electrical conductive rate of 53.04% IACS (international annealed copper standard) and strength remnant rates of 92.44% (180 DEG C*400 h) and 93.63% (230 DEG C*1 h), and obtain relatively good comprehensive performance of samples.

Description
