6063 aluminum pipe 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 pipe profiles are much higher than those of industry Profile standards. Within the composition range of
Forged 6063 aluminum tube specified in 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, preferably the chemical composition of
6063 Forged aluminum tube has become the most important part of producing high-quality aluminum pipe building profiles.
The main alloying elements in 6063 alloy are magnesium and silicon, which have excellent processability, excellent weldability, extrusion and electroplating, good corrosion resistance, toughness, easy polishing, coating, and excellent anodizing effect. , Is a typical extruded alloy, widely used in building profiles, irrigation pipes, pipes, rods, profiles for vehicles, benches, furniture, elevators, fences, etc. The main chemical composition is: Cu; 0.1-, Si; 0.2 -0.6-, Fe; 0.35-, Mn; 0.1-, Mg; 0.45-0.9-, Zn; 0.1-, Cr; 0.1-, Ti; 0.1-
Performance and analysis: Tensile strength σb (MPa): 130 ~ 230 6063 The ultimate tensile strength is 124 MPa Tensile yield strength 55.2 MPa Elongation 25.0% Elasticity coefficient 68.9 GPa
