Abstract

The invention discloses an as-cast state aluminum alloy having an excellent synthetic mechanical performance and a method for preparing the same. The alloy has the fowllowing components by weight: Zn of 9-14%, Sn of 0.5-3%, Pb of 0.05-2.5% and Al of the rest.The method of preparing the alloy comprises steps of performing batching according to the component quality ratio of Zn of 9-14%, Sn of 0.5-3%, Pb of 0.05-2.5% and Al of the rest, putting the matched pure Al ingots, pure Sn bars, pure Pb blocks and Zn ingots into a crucible resistor furnace for heating and melting, when the fused aluminumliquid reach a temperature of 690-710 DEG C, adding a chloride mixed scouring agent of 1-2% for refining for 5-15 minutes, then pouring the fused liquid in the shaping molds to form the as-cast state aluminum alloy with obdurability.

Description

technical field [0001] The invention relates to an as-cast aluminum alloy with good comprehensive mechanical properties and a preparation method thereof, in particular to an as-cast aluminum alloy containing zinc, lead, tin, strontium and titanium, belonging to the technical field of aluminum alloys. 2. Background technology [0002] Aluminum alloys are widely used in the manufacture of industrial products because of their high specific strength and high specific stiffness. However, the cost of existing high-strength and toughness alloys is too high to meet the requirements of various fields of the national economy. [0003] There are currently some studies on aluminum alloys: [0004] Application No. 200510037105.5 proposes an aluminum alloy material, specifically a high-strength and toughness squeeze-cast aluminum alloy material. The extrusion strength can reach 75MPa. The main components and mass percentage of the material are: copper 4.5-5.5%, manganese 0.3-0.6%, trace...
