Abstract

The invention relates to an aluminum alloy material used for making a cable, which comprises the following elements by weight: 0.2-0.4% of Cu, 0.7-0.9% of Fe, 0.05-0.15% of Si, 0.05-0.1% of Mg, 0.01-0.05% of Zn, 0.01-0.04% of B, 0.001-0.02% of Ti, 0.001-0.005% of Cr and the balance of aluminum and inevitable impurity. The cable prepared by the material has strong conductor flexibility, and the material can guarantee the safety performance of the practical application of the aluminum alloy to reach or even exceeds that of the copper core cable, and simultaneously provides very large advantage to the practical installation and application of the aluminum alloy cable, the aluminum alloy cable is easy to be bent during an installation process, installation cost is effectively reduced, and the accident risk is reduced.

Description

technical field [0001] The invention relates to the technical field of electric cables, and more specifically relates to an aluminum alloy material used for making electric cables. Background technique [0002] my country's aluminum resources are very rich, so the price is cheap. In October 2009, the price of copper was about 50,000 yuan / ton, and the price of aluminum was about 15,000 yuan / ton. In the 1970s, my country implemented the policy of "substituting aluminum for copper". However, the conductivity of aluminum is slightly worse than that of copper, and the resistivity is about 1.68 times that of copper, so that the current carrying capacity of aluminum core cables is smaller than that of copper core cables, and the voltage drop is larger than that of copper core cables. An important disadvantage of ordinary aluminum wire is its high brittleness. As long as it is twisted at a certain angle during installation, the conductor will crack, and the crack will generate heat...
