6061 Aluminum
6061 Aluminum is, by most any measure, the most commonly used aluminum alloy. It is specified in most any application due to its strength, heat treatability, comparatively easy machining, and weldability. If that were not enough, it is also capable of being anodized, adding a layer of protection for finished parts.
The main alloy ingredients of 6061 aluminum are magnesium and silicon.
6061-T6 Aluminum
Physical and Mechanical Properties Ultimate Tensile Strength, psi 45,000
Yield Strength, psi 40,000
Brinell Hardness 95
Rockwell Hardness B60
Chemistry Aluminum (Al) 95.8 - 98.6%
Chromium (Cr) 0.04 - 0.35%
Copper (Cu) 0.15 - 0.40%
Magnesium (Mg) 0.8 - 1.2%
Manganese (Mn) 0.15% max
Silicon (Si) 2.8 - 3.8%
Zinc (Zn) 1.5% max
6063 Aluminum
6063 is often called architectural aluminum for two reasons - first, it has a surface finish that is far smoother than the other commercially available alloys, and second, its strength is significantly less (roughly half the strength of 6061), making it suited for applications where strength is not the foremost consideration.
6063 is rated as "Good" for forming and cold working operations, "Excellent" for anodizing, and "Fair" for machining.
6063-T52 Aluminum
Minimum Properties Ultimate Tensile Strength, psi 27,000
Yield Strength, psi 21,000
Brinell Hardness 60
Chemistry Aluminum (Al) 97.5% max
Chromium (Cr) 0.1% max
Copper (Cu) 0.1% max
Iron (Fe) 0.35% max
Magnesium (Mg) 0.45 - 0.90%
Manganese (Mn) 0.1% max
Silicon (Si) 0.2 - 0.6%
