6061 Aluminum Rounds
6061 Aluminum Rounds
6061 aluminum is a precipitation-hardened aluminum alloy containing magnesium and silicon as its major alloying elements. This is the most versatile of the heat-treatable aluminum alloys, offering an exceptional balance of mechanical properties, corrosion resistance, and workability. It can be fabricated using many common techniques, welded by all methods, and is suitable for furnace brazing. Applications include aircraft components, tactical flashlights, bicycle frames, and structural frameworks.
- 6061 Aluminum (UNS A96061)
- Heat-treatable alloy
- Mg-Si precipitation hardened
- Excellent machinability
- Good weldability
Overview
6061 Aluminum Rounds represent the industry standard for versatile, high-strength aluminum bar stock. As a precipitation-hardened alloy containing magnesium and silicon, 6061 aluminum offers an exceptional balance of mechanical properties, corrosion resistance, and workability. This makes it the most widely used heat-treatable aluminum alloy for industrial applications.
In its common T651 temper, 6061 aluminum rounds provide excellent yield and tensile strength, making them ideal for highly stressed components. The alloy's microstructure ensures superior machinability, allowing for complex turning, milling, and drilling operations with excellent surface finishes. Its inherent weldability by all common methods, including TIG and MIG, further enhances its versatility for fabricated structures.
Beyond mechanical performance, 6061 aluminum rounds exhibit outstanding resistance to atmospheric corrosion and are often specified for marine and outdoor applications. The alloy can be easily anodized to increase surface hardness and provide decorative or color-coded finishes. These properties make 6061 aluminum rounds a go-to material for aerospace components, automotive parts, marine hardware, and high-strength structural frameworks.
For B2B buyers, 6061 aluminum rounds deliver consistent quality batch-to-batch, ensuring reliable performance in manufacturing processes. Available in a comprehensive range of diameters from stock, these rounds can be sourced with quick turnaround to meet production schedules. Whether for prototyping or high-volume production, 6061 aluminum rounds provide the optimal combination of strength, weight savings, and cost-effectiveness for demanding industrial applications.
