Embodiment Construction

[0023] First example:

[0024] 10.5% by weight of silicon powder, 2.7% by weight of copper-clad aluminum alloy ingots, 0.3% by weight of magnesium ingots, and 87.1% by weight of aluminum ingots were selected for use. Among them: in silicon powder, the weight content of silicon is ≥98.5%, and its particle size is ≤5mm; in copper-clad aluminum alloy, copper is 30% by weight, and aluminum is 70% by weight; , the content of aluminum ≥ 99.7% by weight.

[0025] First put the aluminum ingot into the melting furnace to melt it into aluminum melt.

[0026] Then the aluminum melt is overheated to 760°C, and silicon powder is added to the aluminum melt with a gas carrier; after that, a copper-clad aluminum alloy ingot and a magnesium ingot are added in sequence, and stirred for 10 minutes to obtain a mixed melt.

[0027] After that, the temperature of the mixed melt was adjusted to 740°C, and the mixed melt was refined by blowing argon in the furnace for 20 minutes, and the scum on th...

Abstract

The invention discloses a high silicon-aluminum alloy and a method for preparation, in particular to the high-silicon aluminum alloy with excellent wear resistance and a method for preparation. The invention comprises 10.5-11.2 percent of silicon powder, 2.2-2.7 percent of copper clad aluminum alloy, 0.2-0.5 percent of magnesium, 85.6-87.1 percent of aluminum, which are made through melting, mixing, first refining, second refining and casting. The high silicon-aluminum alloy has excellent wear resistance, high tensile strength and high tensile strength, and is capable of meeting the performance requirements of an air conditioner of an automobile.

Description

technical field [0001] The invention relates to an aluminum alloy and a manufacturing method thereof. Specifically, it is a high-silicon aluminum alloy with excellent wear resistance and a preparation method thereof. Background technique [0002] As we all know in the machinery manufacturing industry, the requirements for the wear resistance, tensile strength and Brinell hardness of aluminum alloys are getting higher and higher. At present, the high-silicon aluminum alloys used in the machinery manufacturing industry such as the automotive air conditioner manufacturing industry are 4004 aluminum-silicon alloys and 4032 aluminum-silicon alloys produced in accordance with GBT3190-1996, while 4004 aluminum-silicon alloys and 4032 aluminum-silicon alloys The contents of silicon are respectively 9.0% by weight to 10.5% by weight and 11.0% by weight to 13.5% by weight. Al-silicon alloys with silicon content less than or equal to 10% by weight are hypoeutectic Al-silicon alloys, ...
