StayMax Aluminum Engraving Blanks with 2 Holes
These blanks are designed for engraving and light milling tasks. Material is aluminum with a non-magnetic composition, providing good machinability. Each blank measures 1.5 inches by 3 inches with a 0.039 inch thickness and a 0.137 inch hole diameter. While the surface is smooth with no burrs, some blanks may show superficial scratches. The two holes facilitate quick mounting or alignment during work, making them suitable for project boards, signs, and personalized tags.
Maswater Round Aluminum Sheet
Maswater offers a high-strength round aluminum sheet with a 12-inch diameter, crafted from quality aluminum alloy. The round shape provides unique milling and engraving possibilities for discs, plaques, and decorative pieces. The blank ships with a protective film on both sides to minimize surface damage during transit, helping maintain a pristine finish for engraving and cutting operations. This sheet suits enthusiasts needing a durable, large-area stock for round projects or to cut into custom shapes.
LOYORTY Anodized Aluminum Sheet
This LOYORTY sheet features a 6 x 12 inch footprint with 0.04 inch thickness and a robust 5052 aluminum alloy. The black anodized finish delivers a smooth, burr-free surface ideal for laser engraving and DIY metal crafts. The material offers corrosion resistance and good machinability, making it suitable for precise cuts, inlays, and decorative plates. The even thickness and flat surface support consistent milling results and clean edges.
StayMax Round Aluminum Blank Tags
StayMax round blank tags offer a compact, stamping-friendly option. Each piece measures 1.37 inches in diameter with a 0.039 inch thickness and a polished finish. The blanks are designed to be free of sharp edges, minimizing handling risk during engraving or stamping.

ABuff Anodized Aluminum Sheet
ABuff provides four-pack anodized aluminum sheets sized 12 x 6 inches with a thickness of 1/16 inch (1.5 mm). Built from 5052 alloy, these sheets boast corrosion resistance and strong machining characteristics. The surface is processed for smoothness and flatness, with burrs and scratches kept to a minimum. This stock is well-suited for laser engraving, signs, plaques, and decorative panels, offering ample area for multi-piece projects or larger engravings.
Buying Guide: Key Considerations For Aluminum Blanks In Milling Projects
Choosing the right aluminum blanks for milling depends on project requirements, tool compatibility, and finish goals. Consider the following factors to ensure you select stock that performs well in your shop.
- Alloy and Hardness: 5052 is common for engraving and light milling due to good formability and corrosion resistance. For tougher cutting, consider higher hardness grades while balancing machinability.
- Thickness and Flatness: Consistent thickness (like 0.04 inches or 1/16 inch) helps ensure uniform milling depth and clean edges. Look for flat, burr-free surfaces to minimize finishing work.
- Surface Finish: Anodized or painted finishes can improve wear resistance and reduce oxidation during milling, but may require masking or adaptation for engraving.
- Edge Quality: No burrs and minimal sharp edges reduce tooling wear and improve operator safety during setup and handling.
- Size and Shape: Round sheets offer unique design possibilities, while rectangular blanks fit standard engraving or stamping fixtures. Assess whether you need pre-punched holes for mounting or alignment.
- Protective Packaging: Protective films help prevent surface scratches in transit; ensure you remove film before final finishing if needed.

Additional Considerations
– Tolerance: Check the tolerances offered by each product to ensure compatibility with high-precision milling or CNC setups.
– Tooling Compatibility: Ensure your milling bits and feed rates are appropriate for the chosen alloy and thickness to avoid chatter or excessive tool wear.
– Stock Handling: Heavier or thicker blanks may require stronger clamps and careful fixturing to prevent movement during milling.
– Surface Preparation: Post-processing steps such as deburring, sanding, or polishing may be needed to achieve a desired finish, particularly on uncoated blanks.
