Aluminum alloy, preparation method, application of aluminum alloy and related equipment

The invention provides an aluminum alloy, a preparation method, application of the aluminum alloy and related equipment. The aluminum alloy comprises the following components in percentage by mass: 0.001 to 0.01 percent of B; si: 0.005 to 0.04%; 0.1 to 0.3 percent of Fe; 0.005% to 0.03% of Mg; 0.02 to 0.03 percent of Zn; 0.01 to 0.03 percent of Er (Erbium); 0.01 to 0.02 percent of Sr; less than or equal to 0.006% of Cr + Mn + V + Ti; and the balance of aluminum and other inevitable trace impurities. According to the technical scheme provided by the invention, the impurity content in the aluminum alloy conductor is reduced through boronizing treatment, so that the conductivity of the conductor is improved; the mechanical strength of the aluminum alloy is improved by adding the Al-Fe intermediate alloy; the Al-Zn intermediate alloy and the Al-Mg intermediate alloy are added to form a strengthening phase MgZn2, so that the tensile strength and the yield strength are obviously improved; by adding the Al-Er interm
