Abstract
The invention discloses a multi-element micro-alloyed high-strength aluminum-manganese alloy and a preparation method thereof. The multi-element micro-alloyed high-strength aluminum-manganese alloy contains 0.1-0.5% of Mg, 0.3-1.5% of Si, 0.9-1.7% of Mn, 0.1-1.6% of Zn, 0.05-0.2% of Cu and the balance of aluminum, micro-alloying elements and inevitable impurities, wherein the micro-alloying elements preferably comprise one or more of 0.05-0.3% of Ti, 0.05-0.1% of B or 0.05-0.3% of Zr; and a rare earth element selected from one or two of Ce, La, Y, Er or Nd, and the content of each rare earth element is 0.05-0.3%. The multi-element micro-alloyed high-strength aluminum-manganese alloy disclosed by the invention has higher tensile strength and yield strength after a brazing process is performed, the tensile strength after brazing can achieve above 160MPa, and the yield strength can achieve about 60MPa; and furthermore, the corrosion resistance is great.
Description
technical field [0001] The invention relates to the field of aluminum alloys, in particular to a multi-component micro-alloyed high-strength aluminum-manganese alloy and a preparation method thereof, in particular to a multi-component micro-alloyed high-strength aluminum-manganese alloy for heat exchangers and a preparation method thereof. Background technique [0002] The lightweight of automobiles and other means of transportation has become a major project for the strategic development of my country's manufacturing industry. It has the strategic significance of driving the overall development of my country's manufacturing industry and realizing the modernization and high-tech of the manufacturing industry.
