Abstract

The invention discloses a heatproof aluminum alloy material for a cable. The material comprises the following components of a Ti3AlC2 / Cu composite powder material, Al2O3 / Mo5Si3 composite powder, magnesium and manganese intermediate alloy, rare earth aluminum intermediate alloy, aluminum and chromium intermediate alloy and aluminum and silver intermediate alloy with the remaining of aluminum powderand unavoidable impurity thereof. The proper amount of rare earth aluminum intermediate alloy, the Ti3AlC2 / Cu composite powder material with a higher conductivity, the Al2O3 / Mo5Si3 composite powder of a high-temperature material, the aluminum and chromium intermediate alloy, the aluminum and silver intermediate alloy and the like are added o the aluminum powder, crystal grains are thinner, defects in the surface layer is filled, the purity is improved, non-uniform growth of the crystal grains is reduced, the intensity and conductivity of the aluminum alloy are improved, and the prepared aluminum alloy is high in performance and resistant to high temperature and corrosion.

Description

technical field [0001] The invention relates to the technical field of cable materials, in particular to a heat-resistant aluminum alloy material for cables. Background technique [0002] Aluminum alloy cables add copper, iron, magnesium, silicon, zinc, boron and other alloying elements to the electrical aluminum, and at the same time through process adjustment, the mechanical properties of the aluminum alloy conductor are greatly improved, and the low elongation and creep resistance of the pure aluminum conductor are avoided. The problem of poor performance and poor flexibility can be solved, and the connection reliability of the cable system can be increased. Due to the good mechanical and electrical properties of aluminum alloy power cables, it can be widely used in various fields of the national economy, such as ordinary houses, high-rise buildings, elevators, large and small supermarkets, subways, airports, stations, hospitals, Banks, office buildings, hotels, post and...
