Excellent craft
The 6063 aluminum rod is a low alloyed Al-Mg-Si high plasticity alloy. Has many valuable features: 1. Heat treatment strengthening, high impact toughness, can not be sensitive to lack of. 2. It has excellent thermoplasticity and can be extruded at high speed into a complex structure. Thin wall. Hollow various profiles or forged forgings with complex structure, wide quenching temperature range, low quenching sensitivity, after extrusion and forging demoulding, As long as the temperature is higher than the quenching temperature. That is, it can be quenched by spraying water or water. Thin-walled parts (6<3mm) can also be subjected to wind quenching. 3. Excellent welding performance and corrosion resistance, no tendency of stress corrosion cracking. Among heat-treated reinforced aluminum alloys, Al-Mg-Si alloy is the only alloy that has no stress corrosion cracking phenomenon. 4. The surface after processing is very smooth and easy to anodize and color. The disadvantage is that if it is left at room temperature for a period of time after quenching, it will have an adverse effect on the strength (parking effect).
6063 aluminum alloy is a medium strength heat treatable strengthening alloy in AL-Mg-Si system. Mg and Si are the main alloying elements. The main work of chemical composition is to determine the percentage of Mg and Si (mass fraction, the same below) .
1.1 The role of Mg and the influence of Mg and Si on the strengthening phase Mg2Si, the higher the content of Mg, the more the amount of Mg2Si, the greater the heat treatment strengthening effect, the higher the tensile strength of the profile, but the deformation resistance also As the alloy increases, the plasticity of the alloy decreases, the processability deteriorates, and the corrosion resistance deteriorates.
1.2 The role of Si and the influence of Si should be such that all Mg in the alloy can exist in the form of Mg2Si phase to ensure that the effect of Mg is fully exerted. As the Si content increases, the grain size of the alloy becomes finer, the fluidity of the metal increases, the casting performance becomes better, the heat treatment strengthening effect increases, the tensile strength of the profile increases, the plasticity decreases, and the corrosion resistance deteriorates.
The behavior of silicon causing corrosion of 6063 aluminum alloy profiles can be completely prevented and controlled. As long as the raw materials are purchased and the alloy composition is effectively controlled, the ratio of magnesium to silicon is guaranteed to be in the range of 1.3 to 1.7, and the parameters of each process are strictly controlled. To avoid segregation and liberation of silicon, try to make silicon and magnesium form a beneficial Mg2Si strengthening phase.
If such a silicon corrosion point is found, special attention should be paid to the surface treatment. In the degreasing and degreasing process, use a weak alkaline bath as much as possible. If the conditions are not allowed, the time should be soaked in the acidic degreased liquid. Minimize (qualified aluminum alloy profiles in acid degreasing solution for 20 to 30 minutes without problems, and problematic profiles can only be placed for 1 to 3 minutes), and the pH of the subsequent washing water is higher (pH>4, control Cl-content), prolong the corrosion time in the alkali corrosion process, use the nitric acid photo-liquid when neutralizing the light, and oxidize as soon as possible during the anodization of sulfuric acid, so that the dark gray corrosion point caused by silicon is not obvious Can meet the requirements for use
