HOZEON 12 x 12 x 3/8 Aluminum Sheet
The HOZEON aluminum sheet is made from 6061-T651 alloy, offering good processing performance, welding, and electroplating properties. It measures 12 x 12 inches with a thickness of 3/8 inch. The surface is cut evenly with machine precision, ensuring straightness across the sheet. A double-sided protective film helps prevent scratches during transport, maintaining a smooth finish until final machining.
MUKCHAP 11.82 x 11.82 x 3/8 Inch Sheet
Crafted from 6061 aluminum, this MUKCHAP plate blends corrosion resistance with high toughness and stable deformation characteristics. The surface is treated for a smooth finish with clean, square edges. Both sides are protected by films, reducing surface scratches during shipping. The sheet is easy to machine and can be cut on standard equipment without significant warpage, making it suitable for small parts and prototypes.
MUKCHAP 2 Pack 12 x 12 x 3/8 Inch Sheets
This bundle includes two square 12 x 12 x 3/8 inch sheets made from high-quality 6061-T651 aluminum. The plates are hard-wearing with good processing and welding performance. Protective films on both surfaces help prevent scratches in transit, ensuring the plates arrive ready for finishing operations or assembly in manufacturing or crafting projects.
Therwen 2 Pcs 12″ Long Aluminum Flat Bar
Therwen offers two 12-inch flat bars, each 3/8 inch thick and 3 inches wide. Manufactured from 6061 aluminum, these bars are designed for precise fitting in various applications, with a practical margin of error around 0.5 mm. They weld reliably and resist corrosion, making them suitable for DIY builds, framing, or fabricated assemblies that require sturdy stock with a light-to-moderate weight profile.
uxcell 3/8″ Aluminum Flat Bar
uxcell supplies a 3/8″ thick, 2″ wide, 10″ long square aluminum flat bar from 6061 alloy. The bar features an anodized surface and precise dimensions with smooth, machined edges, ideal for construction crafts, brackets, or custom tooling. The weldability and corrosion resistance of the 6061 alloy support a wide range of fabrication tasks while keeping weight manageable for handling and installation.
Buying Guide: Key Purchase Considerations
- Material and grade: For most structural, machining, or fabrication tasks, 6061-T651 aluminum offers a balance of strength, machinability, and corrosion resistance. Verify heat treatment and alloy grade when comparing plates.
- Thickness and size: A 3/8 inch thickness is common for plates and bars used in lightweight structural parts, brackets, or shields. Confirm overall dimensions match your project’s tolerance and drilling patterns.
- Flatness and surface finish: Look for flat sheets with consistent thickness and clean edges. Some options include protective films on both sides to minimize handling scratches during shipping.
- Welding and fabrication: If welding is required, ensure the plate supports easy welding with minimal distortion. Protective films help preserve finish prior to final processing.
- Price and quantity: Determine if a single plate, a pair, or multiple pieces best aligns with your project budget and scale. Bundled packs may offer cost efficiency.
- Machinability: For DIY projects, consider how easily the plate can be cut, drilled, or milled with common tools. A smooth surface reduces finishing time.
- Protection and handling: Protective films are beneficial for transport. Remember to remove films after machining to reveal the intended surface finish.
