Abstract

The invention belongs to the technical field of aluminum alloy production processes, and relates to a high-conductivity 6 series aluminum alloy and a production process therefor. The high-conductivity6 series aluminum alloy is prepared from the following element components in percentage by weight: 0.55%-0.60% of Si, 0.10%-0.15% of Fe, 0.05%-0.08% of Cu, 0.01%-0.02% of Mn, 0.60%-0.65% of Mg, 0.01%-0.02% of Cr, not greater than 0.01% of Ti, 0.05%-0.08% of Zn, not greater than 0.01% of V, 0.15%-0.18% of Gd, 0.015%-0.02% of B, not greater than 0.03% of single impurities, not greater than 0.10% ofimpurities and the balance Al; by improving a formula and the process, the tension strength of the aluminum alloy reaches 250 Mpa, the yield strength reaches 210 Mpa, the percentage elongation afterfracture reaches 16.7%, and the conductivity Gamma is equal to 32.52 MS/m; and the hardness HB is equal to 65, so that the mechanical property and the conductivity of the 6 series aluminum alloy are obviously improved.

Description

technical field [0001] The invention belongs to the technical field of aluminum alloy production technology, and relates to a high-conductivity 6-series aluminum alloy and a production technology thereof. Background technique [0002] The so-called aluminum alloy is to add an appropriate amount of other elements to industrial pure aluminum to improve the nature of aluminum to meet various needs in industry and life. Due to the small specific gravity, high specific strength and good comprehensive performance of aluminum alloy, it is widely used in aviation industry, automobile manufacturing industry, power instrument, tool and civil utensil manufacturing, etc. [0003] With the development of industry, higher requirements have been put forward for the comprehensive performance of 6 series aluminum alloys, and the indicators such as strength, hardness and plasticity, which have been used to test the performance of aluminum alloys, can no longer fully reflect its comprehensive ...
