Effects of Alloy Composition and Annealing Treatment on the Performance of Aluminum Conductor

Abstract:

Discuss how iron, copper and magnesium alloy and rare earth cerium influence the electrical and mechanical properties of aluminum conductor using the orthogonal test, to thereby get the best alloy composition that meets the requirement; through test analysis on the conductivity, intensity and elongation at break of aluminum conductor with the best alloy composition, discuss the influence of different annealing temperature and holding time on their performance. The results show that: the best material composition of the aluminum alloy conductor would be 0.25% Fe, 0.40% Cu, 0.05% Mg, 0.30% Ce, 0.008% B, and aluminum and inevitable impurities. The intensity, elongation at break and conductivity of this aluminum conductor would be 110N/mm2, 30.0% and 62.2%IACS respectively. The best annealing process parameters are annealing temperature of 310°C, and holding time for 30min, direct air cool. The intensity of aluminum conductor processed is 129 N/mm2, and the elongation at break, resistivity, and conductivity are 15.0%, 2.782×10-8Ω•m and 62%IACS respectively. The mechanical properties and conductivity of this aluminum conductor both comply with the requirements of wire and cable conductor cores.
