Abstract

The invention discloses a long-acting modified high-silicon aluminum alloy and a modification process thereof. The high-silicon aluminum alloy comprises the following components of, in parts by weight, 13.5wt%-15.5wt% of Si, 0.55wt%-0.65wt% of Mg, 4.0wt%-5.0 wt% of Cu, less than or equal to 0.5wt% of Mn, less than or equal to 1.0wt% of Zn, less than or equal to 1.3wt% of Fe, less than or equal to0.5wt% of Ni, less than or equal to 0.3wt% of Sn, and balance Al. The modification process comprises the following steps of adding materials to a smelter and refining, adding a modifier for the firsttime, adding the modifier for the second time, degassing and refining solution. By means of the modification method, the high-silicon aluminum alloy with good modification and refinement effects and the deterioration effective time of more than 50 hours in the liquid state can be obtained, so that a product which is capable of avoiding secondary smelting and saving energy consumption can be provided for customers.

Description

technical field [0001] The invention belongs to the technical field of alloy materials, and in particular relates to a long-acting metamorphic high-silicon aluminum alloy and a metamorphic treatment method thereof. Background technique [0002] With the continuous development of aluminum alloy technology, the application fields of aluminum alloy materials are becoming more and more extensive, and the demand for special aluminum alloy materials in different technical fields is increasing. [0003] Especially in high-tech fields such as safety accessories for high-speed automobiles, high-precision electromechanical equipment, and aerospace, there is an increasing demand for materials with excellent properties such as light weight, corrosion resistance, wear resistance, and fatigue resistance, and the quality requirements are becoming more and more stringent. Therefore, it is required that the structure, grain, and air tightness of the material itself must exceed conventional a...
