Product category: DIY Supplies — Metalworking Origin: Mainland China Raw material: aluminium alloy 6061 Specification format: outer diameter x wall thickness x length Why this product helps you Reliable raw material: Made from aluminium alloy 6061, the stock delivers a good combination of strength, corrosion resistance, and machinability for common metalworking tasks. Versatile and easy to work: Suitable for cutting, drilling, milling, turning, and finishing, so you can shape parts quickly without excessive tool wear or complex procedures. Consistent, predictable performance: Using a standard aluminium alloy makes results repeatable from prototype to small production runs. Key features and practical benefits Function: Structural and fabrication stock for DIY and professional metalworking projects — use as tubing, spacers, standoffs, sleeves, or custom machined components. Compatibility: Works with common shop equipment (bandsaw, chop saw, lathe, mill, drill press, and CNC machines) and standard fastening and joining methods (bolting, press fit, adhesives, welding where appropriate). Size definition: Supplied and ordered by outer diameter x wall thickness x length so you can specify exactly the dimensions you need for fit and strength. Material advantages: 6061 aluminum is lightweight yet durable, resists corrosion for general-purpose applications, and accepts secondary processes such as tapping, anodizing, and painting. How it solves common problems Reduces over-spec material waste by letting you choose precise dimensions (OD x wall x length) for the task. Speeds up prototyping and repair by providing material that machines predictably and finishes cleanly. Lowers assembly weight compared with steel alternatives while maintaining adequate strength for many DIY and light industrial uses. Typical applications and use scenarios 1) Hobby and robotics: Cut and machine tubes or spacers for robot frames, gimbals, or sensor mounts where low weight and ease of machining are important. 2) Custom enclosures and fixtures: Create standoffs, brackets, or short runs of custom enclosures for electronics or test fixtures that require corrosion-resistant, machine-ready material. 3) Repair and retrofit: Replace worn sleeves, shafts, or structural elements on bicycles, small machinery, or home equipment using precisely sized stock to restore fit and function. Ordering and selection tips Specify dimensions using outer diameter x wall thickness x length to ensure correct fit and strength for your application. Consider wall thickness relative to load and bending; thicker walls increase rigidity but add weight. If surface finish or secondary processing is required (anodize, paint, tapping), account for machining allowance when specifying length and diameter. Trust and origin Origin: Mainland China. Material supplied as aluminium alloy 6061, consistent with standard 6061 properties used in metalworking and fabrication. If you need help choosing dimensions for your application, provide the required outer diameter, wall thickness, and length so the correct stock can be recommended.
