Abstract

The effects of pre-aging temperature (125°C, 135°C, 145°C) and regression time (5min ~ 25min) on Al-B electric round rod were studied by tensile strength test, conductivity test, XRD and SEM. The results showed that the tensile strength of the alloy first increased and then decreased, while the electrical conductivity decreased first and then increased after re-aging treatment. When the regression and re-aging process is 145 °C × 4h+200 °C × 5min+145 °C × 4h, the comprehensive properties of the sample are better, the tensile strength is 78MPa and the conductivity is 63.1% IACS.
