Problems solved by technology

[0002] As we all know, consumers often put forward high requirements for the visual effect of the surface gloss of anodized aluminum profiles according to the final use of extruded profiles in the fields of building components, electronic cabinets, cabinets, etc. For example, it is required that the aluminum profile should be close to the aluminum metal itself The surface is glossy and has a strong metallic texture. At the same time, the sand surface is evenly distributed and other sensory effects. However, the current conventional 6063 aluminum alloy extruded profiles are difficult to meet the above requirements after anodizing.

Embodiment Construction

[0019] In order to further understand the characteristics and effects of the present invention, the following embodiments are given as examples, and detailed descriptions are as follows in conjunction with the accompanying drawings, please refer to figure 1 .

[0020] Such as figure 1 Shown: The method of obtaining natural aluminum color after anodizing aluminum alloy is as follows:

[0021] ①, 6063 alloy ingot composition optimization: Considering the influence of chemical composition on material uniformity, surface smoothness and brightness, it is necessary to achieve a fine and uniform microscopic crystal structure to reflect the chemical properties of the optimized metallurgical quality of the 6063 alloy. The composition range, the most important of which is the content of iron in the raw material aluminum, and its chemical element composition is:

[0022] Fe≤0.20%, Si=0.33-0.5%, Mg≤0.6%, Mn≤0.1%,

[0023] Cu=0.05-0.25%, Ti≤0.05, Zn≤0.05%;

[0024] ②. Full homogenizati...

Abstract

the invention discloses an acquiring method of natural Al-color, which comprises the following steps: optimizing alloy composition with Fe <=0.20%, 0.33-0.5% Si and Mg<=0.6%; controlling physical metallurgical course to even the ingot at 535-550 deg.c for 8-12 h; heating rapidly before squeezing; cooling; predisposing sand-blasting surface; cleaning artificially; proceeding on-line disposal for anode; changing integrated property of 6063 alloy.

Description

Technical field: [0001] The invention relates to a method for processing aluminum alloy extruded profiles, in particular to a method for obtaining natural aluminum color after anodic oxidation of aluminum alloy. Background technique: [0002] As we all know, consumers often put forward high requirements for the visual effect of the surface gloss of anodized aluminum profiles according to the final use of extruded profiles in the fields of building components, electronic cabinets, cabinets, etc. For example, it is required that the aluminum profile should be close to the aluminum metal itself The surface is glossy and the metal texture is strong, and at the same time, the sand surface is evenly distributed and other sensory effects, but the current conventional 6063 aluminum alloy extruded profiles are difficult to meet the above requirements after anodizing. Invention content: [0003] The main purpose of the present invention is to overcome the above shortcomings and prov...
