Abstract

The invention discloses an aluminum alloy material. The material comprises the following raw materials of aluminum ingots, magnesium ingots, aluminum-silicon alloy, copper blocks, zinc blocks, iron blocks, manganese blocks, magnesium-lanthanum alloy, dysprosium powder, aluminum-neodymium alloy, magnesium-holmium alloy, molybdenum powder, chromium powder, vanadium powder, erbium powder, silicon carbide and refining agents. The aluminum alloy material are prepared through the following steps that alloy liquid is produced and then is subjected to modification treatment, then casting molding and precooling treatment are conducted, and then quenching treatment and tempering treatment and the like are conducted. According to the aluminum alloy material, components and smelting and heat treatmentprocess parameters of the aluminum alloy are optimized, so that the tensile strength and elongation index of products are improved, the tensile strength of the aluminum alloy material reaches 128.9MPa or above, the elongation rate reaches 40.9% or above, the performance requirements of the market and existing product materials can be greatly met, and the material has the significance of wide popularization and application.

Description

【Technical field】 [0001] The invention belongs to the technical field of aluminum alloy production, and in particular relates to an aluminum alloy material and a production process thereof. 【Background technique】 [0002] Aluminum alloys are widely used in automobiles, machinery, aerospace and other fields due to their high cost performance, beautiful shape, good plasticity, high specific strength, good corrosion resistance, and strong processability. [0003] Traditional aluminum alloy die castings have poor tensile strength and elongation, which cannot meet the market and material performance requirements of existing products. The composition, melting and heat treatment process parameters of aluminum alloy all have an important influence on the properties of the plate. How to choose the optimal composition and process parameters has become the focus of current research. 【Content of invention】 [0004] The invention provides an aluminum alloy material and a production pr...
