Abstract

The invention relates to the technical field of aluminum alloys, in particular to a stainless-steel-colored aluminum alloy and a preparation method thereof. The stainless-steel-colored aluminum alloyis prepared from the following components in percentage by weight: 0.38-0.41% of silicon, less than 0.15% of iron, less than 0.1% of copper, less than 0.1% of manganese, 0.48-0.51% of magnesium, lessthan 0.1% of chrome, less than 0.1% of zinc, less than 0.1% of titanium and the balance of aluminum and impurities, wherein the single impurity is less than 0.05%, and the total amount of the impurities is less than 0.15%. The stainless-steel-colored aluminum alloy has the color and gloss of an existing stainless steel profile, has a mirror effect of stainless steel, has the smaller density and lower cost than those of the stainless steel profile, and can replace the existing stainless steel profile to be applied to building decoration.

Description

technical field [0001] The invention relates to the technical field of aluminum alloys, in particular to a stainless steel-colored aluminum alloy and a preparation method thereof. Background technique [0002] Stainless steel profiles can have a mirror-like effect. Polished stainless steel profiles are used in architectural decoration. Because of their mirror reflection, they can achieve the effect of complementing each other with various colors and scenery in the surrounding environment. Moreover, because the polished stainless steel profile has a strong ability to reflect light, with the cooperation of the light, it can form a crystal clear and bright part, which is more eye-catching in the space environment. And existing aluminum alloy, although the production cost is much lower than the cost of stainless steel, but aluminum alloy profiles are mostly matte surface, it is difficult to obtain the mirror effect of stainless steel. Contents of the invention [0003] In ord...
