2 Pcs 1/8″ X 2″ Square Aluminum Flat Bar (16″ Long)
Material: 6061 aluminum plate with silicon and magnesium alloys, offering high strength while staying lightweight. This option emphasizes general-purpose use and easy weldability or machining, ideal for small fabrication tasks and prototype fixtures.
Best for: Light-duty projects, prototyping, and mounting brackets where a square profile is advantageous. The short length and square cross-section simplify drilling and cutting operations.
Caution: Plate dimensions listed include 1/8″ thickness and 2″ width; ensure your fixture tolerances match these measurements to avoid fit issues during assembly.
YOUNTHYE 6061 Round Bar Stock, 1-1/4″ x 16″
Material & properties: 6061 aluminum with good machinability, corrosion resistance, and strength. Designed as solid round rods suitable for turning, drilling, cutting, shaping, and other metalworking tasks.
Best for: Machining projects and workshop stock where a full solid round rod is required for lathe work or precise drilling. Choose this if you need a robust, cylindrical profile for turning or milling.
Limitation: Confirm the diameter and length align with your machine’s work envelope and tooling capabilities before ordering.
LOYORTY 4PCS Square Aluminum Flat Bar, 1x2x8 Inch
Features: Each piece is a 1″ x 2″ x 8″ square flat bar made from 6061 aluminum alloy. The surface is processed for smoothness and flatness with burr-free edges, suitable for precise machining and welding.
Best for: Small craft or hobbyist projects where multiple identical pieces are needed, such as brackets or modular components. The quartet offers good value for bulk art or model-making tasks.
Limitation: The individual bar thickness is 1″, which may be heavier for some delicate assemblies; verify weight and fit in your assembly constraints.
2 Pcs Square Aluminum Flat Bar, 1/4″ Thick x 2″ Wide x 12″
Material overview: Premium 6061 aluminum with high hardness, corrosion resistance, and ease of welding or machining. The 1/4″ thickness increases rigidity for structural tasks or parts needing more strength.
Best for: DIY crafts and engineering projects where a reliable flat bar is needed for mounting, brackets, or fabricating parts with moderate thickness requirements.
Caution: Ensure your cutting method preserves the flatness and prevents burr formation on the edges during processing.
6061 Round USA Aluminum Solid Bar, 3/4″ x 13″
Profile: 6061 round extruded bar stock, 3/4″ diameter, 13″ length. This stock is positioned for general fabrication, including welding, milling, turning, and tooling uses.
Best for: Projects requiring a versatile round profile with a balance of strength and machinability. Suitable for hobbyists and light-industrial fabrication alike.
Limitation: Shorter length may necessitate joining or splicing for larger assemblies; plan cuts accordingly to minimize waste.
2PCS 1-1/2 Inch Aluminum Round Rod
Specification: Diameter 1-1/2″ (38 mm), length 16″ (400 mm). Solid 6061 aluminum round bars suitable for heavy-duty turning, shaping, and component fabrication.
Best for: Industrial or school shop projects needing larger round stock for robust fixtures or prototypes. The diameter supports substantial machining without excessive tool wear.
Limitation: Larger diameter requires compatible tooling and spindle capacity; check machine limits before use.
LOYORTY 3PCS 1 Inch Solid Round Aluminum Rod
Material: 6061 aluminum rods with corrosion resistance and good oxidation performance. Each rod is 1″ diameter and 13″ long, suitable for multiple small-to-medium projects.
Best for: DIY craft and small fabrication where common rod sizes reduce the need for custom stock. The set provides multiple pieces for rapid prototyping or batch work.
Limitation: 13″ length may require splicing or additional cuts for longer assemblies; plan accordingly to minimize waste.
LOYORTY 2PCS 2x2x6 Inch Aluminum Flat Bar
Two-piece set: Each bar is 1.97″ x 1.97″ x 6″ (50x50x150mm) made from 6061 aluminum. The surface is flat and smooth, designed for precision machining and welding.
Best for: Projects needing a thicker, square stock with a compact footprint, such as small enclosures, brackets, or test fixtures.
Limitation: The 6″ length may require joining if longer spans are needed in your design.
Buying Guide: Key Considerations For 6061 Aluminum Bar Stock
- Purpose and load: Choose round bars for turning and milling, flat bars for brackets and frames, or square bars for rigid assemblies. Consider expected loads and machining requirements.
- Alloy properties: 6061 offers good machinability, weldability, corrosion resistance, and strength-to-weight. If you need extra strength, verify the thickness and cross-section.
- Size compatibility: Confirm length, width, thickness, or diameter fits your equipment’s capabilities and the intended project geometry.
- Finish and tolerances: Look for precisely cut edges and flat faces when required by your design. Burr-free edges save time during fabrication.
- Quantity and planning: Sets that include multiple pieces help with bulk projects or prototyping. Consider whether you will need additional stock for future tasks.
- Application environment: If exposure to moisture or chemicals is likely, confirm corrosion resistance and protective coatings if applicable.
FAQ
- What is 6061 aluminum best used for in bar stock?
6061 is widely used for general fabrication, machining, and welding due to its balance of strength, machinability, and corrosion resistance.
- Should I buy round or square stock for a project?
Round stock is preferred for lathe work and rotational components; square stock is often better for brackets, mounts, and flat assemblies where surface area matters.
- Is there a risk of burrs with these stock options?
Some products mention burr-free edges; always inspect cut surfaces and deburr as needed before assembly.
- How do I choose the right length?
Measure the project span and add a safety margin for cutoffs, then select the stock length that minimizes waste.
- Can these bars be welded?
Yes, 6061 aluminum welds well with proper technique, making it suitable for frames and fabrications.
