Abstract

The invention discloses an aluminum alloy material for an aluminum piston and a machining method of the aluminum alloy material. The aluminum alloy material for the aluminum piston is prepared from, by weight, 10-15% of silicon, 0.8 to 2.5% of nickel, 0.5 to 3.5% of copper, 0.32 to 0.67% of magnesium, 0.35 to 0.55% of manganese, and the balance of aluminum and inevitable impurities, wherein the sum of the weight percentages of all the components is 100%; the machining method of the aluminum alloy material comprises the following steps of putting secondary aluminum and electrolytic aluminum into a material concentration reverberatory furnace, mixing and heating to 850 DEG C until melting to obtain molten aluminum, cooling to 740-755 DEG C after melting, sequentially adding silicon, copper,magnesium, manganese and nickel elements, blending all raw material components, Refining treatment is carried out, and after refining, deslagging, degassing, casting and homogenizing treatment are carried out, aluminum alloy material is obtained. The impact resistance, the tensile strength and the high-temperature resistance of the aluminum alloy material are improved.

Description

technical field [0001] The invention belongs to the technical field of alloy material processing, and in particular relates to an aluminum alloy material for an aluminum piston and a processing method thereof. Background technique [0002] The piston is the core component of the automobile engine, and it is the key development direction of "Industrial Strong Foundation". With the formulation of the National VI emission standard and its early implementation in some cities, especially self-owned brand car companies, due to insufficient preparation of technology and models, they will be seriously affected. The emission upgrade from China V to China VI involves the upgrade of the entire automobile industry chain. The requirements for energy saving and emission reduction of diesel engines for non-road machinery will definitely increase simultaneously. Therefore, performances such as fuel efficiency and impact resistance of non-road diesel engines will be further improved. On t...
