Aluminum-silicon-strontium-titanium-zirconium alloy and aluminum-silicon-strontium-titanium-zirconium alloy welding wire prepared from same

The invention relates to an aluminum-silicon-strontium-titanium-zirconium alloy and an aluminum-silicon-strontium-titanium-zirconium alloy welding wire prepared from the aluminum-silicon-strontium-titanium-zirconium alloy, and belongs to the technical field of aluminum alloy welding wires. The alloy comprises the following components in percentage by weight: 4.50 to 5.50 percent of Si; 0.01 to 0.05 percent of Mg; 0.02 to 0.50 percent of Sr; ti: 0.01 to 0.15%; zr: 0.01 to 0.20%; 0.01% to 0.10% of La; 0.01 to 0.15% of Ce; c: lt; 0.0010% of the total weight of the raw materials; the balance is Al and inevitable impurity elements, and the content of the inevitable impurity elements is smaller than 1.0 wt%. The invention further discloses an aluminum-silicon-strontium-titanium-zirconium alloy welding wire prepared from the aluminum-silicon-strontium-titanium-zirconium alloy. By controlling the alloy components and the content of all the components, the whole formed welding wire has excellent performance in the asp
