Abstract

The embodiment of the invention provides a magnesium alloy and a preparation method thereof. The magnesium alloy comprises, by mass, 1.6%-2.5% of aluminum (Al), 0.6%-1.5% of zinc (Zn), 0.002%-0.1% of Cerium (Ce), 0.1%-0.5% of manganese (Mn), not larger than 0.015% of inevitable impurities and the balance magnesium (Mg). Due to the fact that the magnesium alloy comprises 0.002%-0.2% of Cerium (Ce) by mass, meanwhile, the content of the aluminum (Al) element in the magnesium alloy is 1.6%-2.5%, and the magnesium alloy has the corrosion resistance, high structural mechanics performance and high extrusion molding processing performance.

Description

technical field [0001] The invention relates to the field of metal materials, more specifically, to a magnesium alloy and a preparation method thereof. Background technique [0002] Magnesium alloy is currently the metal structural material with the lowest density in industrial applications. Because of its high specific strength and specific stiffness, good damping, easy cutting, strong electromagnetic shielding ability, easy recycling, and environmental friendliness, it has gradually become a One of the most competitive metal structural materials, it has been widely used in communication electronics industry, automobile industry, aerospace industry and many other fields. [0003] Many structural parts in communication equipment are processed on the basis of aluminum profiles. However, as the demand for lightweight structural parts of communication equipment continues to increase, aluminum alloys cannot meet the requirements due to their high density. The density of magnesiu...
