6063 Aluminum Round Bar Description
6063 aluminum bar is a low-alloyed Al-Mg-Si high-plasticity alloy with good characteristics and numerous applications. 6063 aluminum has a relatively low strength but superior corrosion resistance and a smoother surface than other aluminum alloys.
6063 aluminum bar contains aluminum (Al, balance), silicon (Si, 0.20~0.60%), copper (Cu, ≤0.10%), magnesium (Mg, 0.45~0.9%), zinc (Zn, ≤0.10%), manganese (Mn, ≤0.10%), titanium (Ti, ≤0.10%), chromium (Cr, ≤0.10%), iron (Fe, ≤0.35%), and other elements with a content of less than 0.05%.
The mechanical qualities of 6063 aluminum bars are superior. The material has a tensile strength (σb) ranging from 130 to 230 MPa, an ultimate tensile strength of 124 MPa, a tensile yield strength of 55.2 MPa, elongation of 25.0%, elastic coefficient of 68.9GPa, bending limit strength of 228 MPa, bearing yield strength of 103 MPa, and fatigue strength of 62.1 MPa.
6063 aluminium bar or rod offers excellent welding performance and is resistant to stress corrosion cracking.
Among aluminum alloys that can be reinforced by heat treatment, Al-Mg-Si alloys are the only ones that do not exhibit stress corrosion cracking.
Consider alloy 6061 for applications where maximum strength is more critical than corrosion resistance. Alloy 6063 is the most widely used aluminum alloy for extrusions. It has significantly superior corrosion resistance and an extremely beautiful surface finish that is ideal for anodizing.
