Abstract

The invention discloses a novel aluminium alloy with high electrical conductivity and high yield strength. The elements in aluminium by weight percentage of the novel aluminium alloy are: 0.55 to 0.70 percent of Fe, 0.20 to 0.30 percent of Cu, 0.10 to 0.20 percent of Si, and less than 0.15 percent of other impurities with single impurity less than 0.05 percent. When the electrical conductivity of the aluminium alloy is not lower than 59 percent IACS, the yield strength RP0.2 of a processed product can reach over 90 N / mm<2>. The aluminium alloy is applicable to an aluminium alloy processed product requiring high electrical conductivity and high yield strength, such as an induction plate used for a maglev train rail.

Description

technical field [0001] The invention relates to an aluminum alloy material, which has high electrical conductivity and high yield strength, and is suitable for application fields such as induction plates for maglev train tracks. Background technique [0002] In some special fields, such as induction plates for maglev train tracks, aluminum alloys are required to have both high electrical conductivity and high yield strength. However, although the electrical conductivity of existing aluminum alloy materials can reach 60% IACS, it can meet the requirements, and the yield strength R in the processed state P0.2 40N / mm 2 about. Contents of the invention [0003] The purpose of the present invention is to provide an aluminum alloy with high electrical conductivity and high yield strength, so as to meet the special needs of induction plates for magnetic levitation train tracks and the like. [0004] The present invention adopts the following technical scheme: a new aluminum al...
