A 6-1/2″ aluminum round bar 6061-T6 is a solid cylindrical rod made from 6061 aluminum alloy, with a diameter of 6-1/2 inches (6.500″). This size is often used for heavy-duty structural, mechanical, and custom-machined parts that require high strength, durability, and resistance to corrosion, while benefiting from aluminum’s lightweight properties.

📐 Basic Specifications:

• Diameter: 6-1/2 inches (6.500″ or ~165.10 mm)
• Material: Aluminum Alloy 6061
• Temper: T6 (solution heat-treated and artificially aged)
• Shape: Solid round bar (not hollow)

🧪 6061-T6 Aluminum Properties:

• Tensile Strength: ~45,000 psi
• Yield Strength: ~40,000 psi
• Hardness: Brinell ~95
• Corrosion Resistance: Excellent — resistant to corrosion, ideal for marine, outdoor, and industrial environments
