Abstract

The invention discloses a special aluminum alloy for automobile transmission pump bodies and a preparation method thereof. The aluminum alloy is composed of the following components in percentage by mass: 16.50-17.00% of Si, at most 1.00% of Fe, 0.55-0.60% of Mg, 4.30-4.60% of Cu, at most 0.45% of Mn, 0.50-1.30% of Zn, at most 0.09% of Ni, at most 0.09% of Ti, at most 0.09% of Pb, at most 0.003% of Ca, at most 0.002% of Na, 0.006-0.015% of P and the balance of Al. The preparation method comprises the following steps: smelting primary aluminum ingot, silicon, pure metal copper, pure metal magnesium, AlFe10 interalloy, zinc part, aluminum-phosphorus alloy and phosphorus-rich alloy, refining, standing and casting. The aluminum alloy material is specially used for preparing automobile transmission pump bodies, has the advantages of higher wear resistance, higher tensile strength, higher thermal cracking resistance and high mold-filling capacity, and can prolong the service life of the automobile transmission pump bodies.

Description

technical field [0001] The invention relates to an aluminum alloy and a preparation method thereof, in particular to an aluminum alloy specially used for an automobile transmission pump body and a preparation method thereof, and belongs to the technical field of aluminum alloy material production. Background technique [0002] Aluminum alloy materials are the most widely used non-ferrous metal structural materials in the industry, and have been widely used in aviation, aerospace, automobiles, machinery manufacturing, shipbuilding and chemical industries. According to the processing method, aluminum alloy can be divided into two categories: deformed aluminum alloy and cast aluminum alloy. Aluminum alloy has low density, but relatively high strength, which is close to or exceeds high-quality steel. It has good plasticity and can be processed into various profiles. It has excellent electrical conductivity, thermal conductivity and corrosion resistance. It is widely used in indu...
