ZOFORTY 2 x 4 x 8 Inch Aluminum Bar
The ZOFORTY aluminum bar stock measures 2 x 4 x 7.9 inches and is made from 6061 aluminum. It offers solid corrosion resistance, good weldability, and reliable machinability, making it suitable for milling, lathe work, and cutting tasks. The bar can be easily machined or welded with standard milling machines or lathes, and it can be cut to length to match your project requirements. This option provides a durable, general-purpose block for a wide range of fabrication projects.
5 Pack: 4 x 2 x 1 Inch Aluminum Flat Bars
This set includes five bars, each measuring 4 x 2 x 1 inches. Crafted from 6061 aluminum, these bars deliver corrosion resistance, good weldability, and straightforward machining. They are suitable for small fixtures, jig components, or test pieces. They cut, drill, tap, and weld with typical workshop equipment, and can be trimmed to fit precise specifications for milling or lathe operations.
4 PCS: 8 x 2 x 1 Inch Aluminum Flat Bars
Each bar in this set is about 7.9 x 2 x 1 inches, providing longer stock for projects requiring extra length. Made from 6061 aluminum, these bars resist corrosion and are easy to machine, drill, tap, or weld. They can be cut to length to fit milling or lathe workflows and are well-suited for larger craft or industrial applications that demand consistent dimensions.
2 PCS: 2 x 2 x 6 Inch Aluminum Flat Bars
These two bars measure 2 x 2 x 6 inches, offering compact stock ideal for precision fixtures and small component fabrication. Crafted from 6061 aluminum, they provide dependable corrosion resistance and straightforward machining. The bars are designed for easy cutting, drilling, tapping, or welding with standard milling or lathe equipment and can be tailored to specific project dimensions.
MOUYAT 3 Pieces: 1 x 2 x 8 Inches
Materially, these 1 x 2 x 8 inch bars are 6061 aluminum, offering good toughness and a high strength-to-weight ratio. The bars have a smooth satin finish and neatly cut edges with minimal burrs. They are designed to be easily machined, cut, drilled, or welded for milling or lathe work and can be heat-treated for certain applications. The 3-piece pack provides flexible options for place-and-fit projects or multiple test pieces.
Buying Guide
- Material and alloy: Most countertop and workshop blocks use 6061 aluminum for its balance of strength, machinability, and corrosion resistance. Verify the alloy to ensure compatibility with your operations and coatings.
- Dimensions and volume: Consider your milling or lathe setup to determine if you need longer bars, wider faces, or thicker cross-sections. Stock dimensions directly influence fixture design and cutting depth.
- Finish and tolerances: Smooth, burr-free edges reduce tool wear and injury risk during setup. Check for provided tolerances and any finish specifications that affect fit in a jig or vise.
- Pack size and cost effectiveness: Multi-pack options can reduce per-piece cost and simplify stocking for recurring projects. Compare per-bar pricing and total project needs.
- Machinability and workability: Favor bars described as easy to machine, drill, tap, or weld if your workflow includes CNC or manual milling. The ease of machining can affect production speed and accuracy.
- Durability and performance: For heavy milling work, prioritize blocks with consistent dimensions and robust material quality to minimize chatter and maintain accuracy across cuts.
- Compatibility with tools: Ensure the bar size matches your milling machine’s vise capacity and the gripping capability of your setup. Some projects may require multiple smaller pieces rather than a single long stock.
When selecting aluminum blocks for milling, balance your immediate project needs with long-term tool life and workflow efficiency. The featured options provide a mix of single bars and multi-pack assortments that suit hobbyist shop benches and small-to-midscale manufacturing tasks alike.
