Buying Guide: Key Considerations For Extruded Aluminum Stock Shapes
- Material grade: 6061 aluminum is a common choice for its strength-to-weight ratio, good corrosion resistance, and ease of machining. Consider 6061 for most general-purpose applications.
- Shape and size: Hex bars are ideal for turning and fabrication where hex interfaces are needed; round rods excel in axial symmetry and turning operations; flat bars support plate-like projects and welding foundations.
- Diameter and thickness: Match the stock dimensions to your tooling and machining capabilities. Thicker stock may require more robust equipment and slower feed rates.
- Length: Ensure the length is sufficient for your project or multiple parts. Longer stock can be cut to size, but review setup constraints on your machine.
- Weldability and finishing: 6061 responds well to welding and can be machined cleanly; consider surface finish if you plan anodizing or coating.
- Application scope: For structural components, assess load requirements, corrosion exposure, and environmental conditions to select the appropriate stock type.
- Availability and sourcing: Availability varies by supplier. Check lead times and compatible tooling (cutters, drill bits, lathe settings) for best results.
- Cost considerations: While not listing prices here, compare unit costs per inch/foot and consider waste when choosing stock sizes for a given project.
