Abstract

The invention relates to an aluminum alloy pole material for producing electric wires and cables and belongs to the technical field of electric wires and cables. The aluminum alloy pole material comprises the following components in percentage by weight: 98.91%-99.2% of Al, 0.08%-0.1% of Si, 0.5%-0.6% of Fe, 0.2%-0.25% of Cu, 0%-0.05% of Mg, 0%-0.05% of Zn and 0.02%-0.04% of B, wherein Mg and Zn are not 0%, and the aluminum alloy pole material is prepared by adding Si, Fe, Cu, Mg, Zn and B in Al in a hot melt state in proportion. The aluminum alloy pole material provided by the invention overcomes the defects in the prior art that copper resources are in shortage and costly, and an aluminum alloy has low strength intensity and poor creep resistance. The aluminum alloy pole material has incomparable use advantages in the electric wire and cable industry.

Description

technical field [0001] The invention relates to an aluminum alloy rod, which is used for producing electric wires and cables, and belongs to the technical field of electric wires and cables. Background technique [0002] At present, in the wire and cable industry, most of them are copper conductors. As a strategic resource, copper is a high-energy-consuming product with low reserves and high cost, while ordinary aluminum conductors have defects such as low strength and poor creep resistance, which prevent them from being widely used. Based on this, the present invention is proposed. Contents of the invention [0003] In order to solve the shortage of copper resources used in the wire and cable industry, the problem of high cost, and the defects of ordinary aluminum rods such as small resistance to strength and poor creep resistance, the invention provides a high-performance aluminum alloy for the production of wires and cables. alloy rod. [0004] To achieve the above o...
