Abstract

The invention relates to the technical field of secondary aluminum, in particular to an aluminum alloy material and a preparation method thereof. The aluminum alloy material is prepared from waste aluminum and a component A in a weight ratio of 8: 1. In the waste aluminum, the iron content is less than 1.0 wt% of the total amount of the waste aluminum, the zinc content is less than 0.3 wt% of thetotal amount of the waste aluminum, the copper content is less than 0.3 wt% of the total amount of the waste aluminum, and the aluminum content is more than 80.0 wt% of the total amount of the waste aluminum. The component A comprises the following raw materials in percentage by weight: 0.2-0.6% of silicon, 0.45-0.9% of magnesium, 0.01-0.08% of manganese, 0.01-0. 08% of nickel, 0.01-0.08% of chromium, 0.005-0.01% of scandium, and the balance of aluminum and impurities, wherein the sum of impurities is less than or equal to 0.15%. Compared with the existing primary aluminum alloy, the aluminumalloy material has equivalent tensile strength, yield strength and glossiness, and is lower in production cost.

Description

technical field [0001] The invention relates to the technical field of recycled aluminum, in particular to an aluminum alloy material and a preparation method thereof. Background technique [0002] Recycled aluminum is an aluminum alloy or aluminum metal obtained by re-melting and refining waste aluminum and aluminum alloy materials or aluminum-containing waste materials. It is an important source of metal aluminum. Secondary aluminum comes mainly in the form of aluminum alloys. [0003] Compared with the primary aluminum alloy, the existing secondary aluminum alloy has lower tensile strength and yield strength, and the surface gloss is greatly reduced. It is difficult for the existing secondary aluminum alloy to replace the primary aluminum alloy for normal use. Contents of the invention [0004] In order to overcome the shortcomings and deficiencies in the prior art, the object of the present invention is to provide a high-strength, high-gloss aluminum alloy material. ...
