The representative alloy of 6063 has lower strength than 6061 and good extruding properties. It can be used as a profile with complex cross-sectional shapes, and has good corrosion resistance and surface treatment.
Europium is a low-alloyed Al-Mg-Si series high-plasticity alloy. Has many valuable characteristics: 1. heat treatment strengthened, high impact toughness, not sensitive to lack.
2. Has excellent thermoplasticity, can be extruded into complex structures at high speed. Thin-walled. Hollow various profiles or forgings with complex structure forging, wide quenching temperature range, low quenching sensitivity, after extrusion and forging demolding, As long as the temperature is higher than the quenching temperature. That is, it can be quenched by spraying water or passing through water. Thin-walled parts (6 <3mm) can also be air-quenched.
3. Excellent welding performance and corrosion resistance, no tendency to stress corrosion cracking. Among heat-treatment-strengthable aluminum alloys, Al-Mg-Si series alloys are the only alloys where no stress corrosion cracking is found. 4. After processing, the surface is very smooth and easy to anodize and color. The disadvantage is that if it is aged at room temperature for a period of time after quenching, it will adversely affect the strength (parking effect).
6063 aluminum alloy is widely used in the construction of aluminum doors, windows and curtain walls. In order to ensure the high wind pressure resistance, assembly performance, corrosion resistance and decoration performance of doors, windows and curtain walls, the comprehensive performance requirements of aluminum alloy profiles are much higher than those of industry. Profile standards. Within the composition range of 6063 aluminum alloy specified in the national standard GB / T3190, different values of chemical composition will result in different material characteristics. When the range of chemical composition is large, the performance difference will fluctuate within a large range. , So that the overall performance of the profile will not be controlled. Therefore, it is preferable that the chemical composition of 6063 aluminum alloy becomes the most important part for producing high-quality aluminum alloy building profiles. The role of alloying elements and their effects on properties 6063 aluminum alloy is a heat-strengthable alloy with medium strength in the AL-Mg-Si series. Mg and Si are the main alloying elements.
