Effect of Boron Content on Mechanical Properties and Electrical Conductivity of 1070 Aluminum Alloy
In this paper,the effects of different boron content on the electrical conductivity and mechanical properties of 1070 aluminum alloy is studied by chemical composition detection,optical microstructure,mechanical tensile and electrical conductivity at room temperature.The results show that the yield,tensile strength and elongation after fracture increase by 25.3%,19.3%and 8.9%,respectively,when boron content is 0.1%.The conductivity was increased from 60.6%IACS to 62.9%IACS,and the electrical conductivity and mechanical properties of 1070 aluminum alloy are the best.
