6061-T6 Aluminum Flat Bar - 3/4" x 4" x 144"
This 3/4" thick by 4" wide 6061-T6 Aluminum Flat Bar meets ASTM B211 standards, delivering 45,000 PSI tensile strength and excellent corrosion resistance. Its high strength-to-weight ratio makes it ideal for structural framing, base plates, and machined components. In stock Los Angeles.
- 6061-T6 Aluminum Construction
- ASTM B211 Certified
- 45,000 PSI Tensile Strength
- Excellent Weldability & Machinability
6061-T6 aluminum is a precipitation-hardened alloy containing magnesium and silicon, making it one of the most versatile heat-treatable grades. The T6 temper signifies it has been solution heat-treated and artificially aged to achieve optimal strength. This process results in a material with a high strength-to-weight ratio, excellent corrosion resistance, and good machinability and weldability, conforming to ASTM B211 standards for rolled or drawn bar.
As a large-profile flat bar, this 4-inch wide stock provides a substantial, stable base for structural applications. It is frequently used for machinery mounting plates, heavy-duty support brackets, gussets for frame reinforcement, and components for transportation equipment where its combination of strength, light weight, and durability is a key advantage.
