Abstract

The invention relates to 6-series aluminum alloys. The 6-series aluminum alloys are composed of the following components in percentage by weight: 0.75-1.1% of magnesium, 0.01-0.02% of titanium, 0.06-0.13% of manganese, 0.5-0.7% of silicon, 0.55-0.7% of copper, 0.005-0.01% of strontium, 0.002-0.008% of pickaxe, not more than 0.13% of iron, not more than 0.01% of zinc, not more than of 0.01% of chromium and the balance of aluminum. The invention also relates to a preparation method of the 6-series aluminum alloys. The 6 series aluminum alloys have the advantages that alloy mechanical propertiesare obviously improved and glossiness is high after the alloys are subjected to highlight oxidation.

Description

technical field [0001] The invention relates to aluminum alloy technology, and its characteristics relate to a 6-series aluminum alloy and a preparation method thereof. Background technique [0002] Aluminum alloys are made by adding some alloying elements to pure aluminum, such as Al-Mn alloys developed by adding manganese elements to pure aluminum, Al-Cu alloys developed by adding copper elements to pure aluminum, and copper added to pure aluminum at the same time. Al-Cu-Mg series hard aluminum alloys were developed with magnesium elements, and Al-Zn-Mg-Cu series superhard aluminum alloys were developed by adding zinc, magnesium, and copper elements to pure aluminum at the same time. Aluminum alloy is characterized by lightness, high strength, good heat dissipation, good hand feeling and easy anodizing and coloring. Under the same strength requirements, aluminum alloy parts can be made thinner and lighter than plastic parts, and at the same time can meet the requirements ...
