Embodiment 1

[0027] Take 80 parts by weight of ADC12 and 20 parts by weight of Al6061, according to the conventional aluminum alloy manufacturing process, put them into the furnace to melt into a liquid state, then put the mixed liquid into the mold for die-casting, take out the profile after die-casting, remove the nozzle, and carry out the process on the profile Post-processing, including conventional processing methods such as peak removal, polishing, grinding and other processing, for future use.

[0028] Perform the following process operations on the processed profiles in turn:

[0029] A. Hanging of the profile, that is, hanging the aluminum alloy profile on a hanger; the hanger can be bent by using a general iron wire. The hanging profile must maintain a certain inclination (> 5°) to facilitate exhaust during electrophoresis or coloring, and reduce spots (bubbles). Points are generated on the decorative surface. Before assembling, place an aluminum sheet between the profile and t...

Abstract

The invention relates to an aluminum alloy suitable for die casting and capable of obtaining the oxidizing protection and an oxidizing colored process thereof. The aluminum alloy contains ADC12 and 6# aluminum, wherein the mass percentage of the ADC12 is 20%-80% and the mass percentage of the 6# aluminum is 20%-80%. The above raw materials, namely ADC12 and 6# aluminum, are put into a smelter together to be melted into liquid. Then the mixed liquid is put in a die for die casting so as to prepare the aluminum alloy. Al 6061 or Al 6063 is adopted as the 6# aluminum. The invention combines the performance complement between the ADC12 and the 6# aluminum to obtain oxidation protection without changing the physical properties of die-casting aluminum alloy ADC12 and greatly enhance the use performance of the aluminum alloy. Meanwhile, by adding pigments in the aluminum alloy, the whole interior and exterior profiles are enabled to be colorful. Therefore, the hue of the profiles is no longer dull due to different colors, so as to meet the requirement of consumers. The oxidizing colored process of the aluminum alloy products has the advantages of plumpy, uniform, level and smooth coatings and obviously better rigidity, adhesive force, erosion resistance, impact property and permeability than other coating techniques.

Description

Technical field: [0001] The invention relates to the technical field of aluminum alloy products, in particular to an aluminum alloy suitable for a die-casting process and capable of obtaining oxidation protection and an oxidation coloring process for the aluminum alloy product. Background technique: [0002] Aluminum alloy materials are widely used due to their good properties. According to the content and type of alloying elements in the aluminum alloy, the corresponding properties of various aluminum alloys are also very different. Among them, commonly used Al-Si-Cu-Mn series die-casting aluminum alloys such as No. 12 aluminum (ADC12) have good die-casting properties and are suitable for manufacturing die-casting profiles through die-casting processes. The profile made of ADC12 has good mechanical properties, but because ADC12 is difficult to be oxidized, the profile made of ADC12 cannot obtain an oxidation protection layer, which affects its service life, and it is also ...
