Lvbang 6063: 6063 is a low-alloyed aluminum rod Al-Mg-Si alloy series of high plasticity. Has many valuable features: a heat strengthened, impact toughness, sensitive to the lack of time to. 2. There is an excellent thermoplastic, high speed extruded into complex structures - Thin various profiles or hollow forged into complex forgings, wide quenching temperature range, low quench sensitivity, after extrusion and forging stripping, as long as the temperature is higher than quenching temperature. Then quenched with water spray or wear approach. Thin-walled parts (6 <3mm) can also carry out air quenching. 3. weldability and excellent corrosion resistance, no stress corrosion cracking tendency, in the heat treatment can be strengthened aluminum alloy, Al-Mg-Si alloy is only found no stress corrosion cracking of the alloy. 4. After processing the surface is very smooth and easy to anodizing and coloring. The disadvantage is that if parked for some time after quenching at room temperature adversely affect (parked effect) in aging, will strength. Influence of alloying elements on the performance: 6063 is the AL-Mg-Si system has a moderate-intensity heat strengthened alloy, Mg and Si is the main alloying elements, the main work is to determine the chemical composition of the preferred percentage of Mg and Si (mass fraction). The role and impact of 1.1 Mg Mg and Si strengthening phase Mg2Si, Mg content of the higher number of Mg2Si on the more, the greater the effect of heat treatment to strengthen the tensile strength of the higher profile, but also with the deformation resistance The increase, decrease the alloy plasticity, workability deterioration, corrosion resistance deteriorates. 1.2 Si Si affect the role and number should make all the Mg alloy can exist in the form of Mg2Si phase to ensure that the role of Mg into full play. With increasing Si content, grain alloy thinner, metal mobility increases, performance becomes better casting, heat treatment to strengthen the effect of increasing the tensile strength and ductility raise the profile of reduced corrosion resistance deteriorates.
