Abstract

The invention discloses an aluminum alloy used for casting a pot and a preparing method of the aluminum alloy. The aluminum alloy is formed by smelting an aluminum alloy base body and an additive. The additive is composed of iron powder, magnesium oxide powder, rare earth fluoride, nano-zinc powder, potassium permanganate, rutile powder, sodium fluosilicate, modified silicon dioxide, bentonite and sodium carbonate. The modified silicon dioxide is formed by adding acetic acid into a deionized water solution of tetraethyl orthosilicate for hydrolysis. Due to the fact that the substance including the iron powder, the magnesium oxide powder, the nano-zinc powder and the like is added into the aluminum alloy base body, the potassium permanganate is decomposed to generate oxygen and manganese dioxide at a high temperature, the generated manganese dioxide can be arranged in the aluminum alloy base body in a filling manner to enhance wear resistance of the base body, furthermore, the iron powder in the aluminum alloy can be oxidized, and therefore iron oxide, magnesium oxide and aluminum oxide can be combined at the high temperature to generate wild phases similar to iron-aluminum spinel and magnesia-aluminum spinel; and the wild phases are dispersed and distributed in a whole system, and therefore the melting point, strength and wear resistance of the final aluminum alloy are improved.

Description

technical field [0001] The invention relates to an aluminum alloy in the field of metal materials, in particular to an aluminum alloy used for casting pots and a preparation method thereof. Background technique [0002] The aluminum pot has the advantages of lightness, durability, fast heating, uniform heat conduction, and no rust. The material of the cast aluminum pot is aluminum and aluminum alloy. Due to the low hardness and low melting point of pure aluminum, the pots made of pure aluminum are easy to be bumped and deformed during use. Therefore, in the prior art, aluminum alloys are mostly used to manufacture pots. [0003] Copper, zinc, manganese, silicon, magnesium and other alloying elements are usually used in aluminum alloys, which have low density, but relatively high strength, which is close to or exceed high-quality steel, good plasticity, can be processed into various profiles, and has excellent electrical conductivity and thermal conductivity. and corrosion r...
