1″ x 3.89″ x 3.89″ 7075-T651 Aluminum Plate
This 7075-T651 plate from Online Metal Supply provides a compact, high-strength option suitable for precise fabrications and small-scale mechanical parts. The plate’s 1 inch thickness and 3.89 inch width and length support prototypes or components requiring tight tolerances. The 7075 alloy benefits from excellent strength-to-weight characteristics, making it a strong choice for load-bearing applications where weight is a concern. Suitable for milling, drilling, and shaping with standard shop tools.
2-1/2″ x 18″ x 18″ 7075-T651 Aluminum Plate
Offering a larger footprint, this 7075-T651 plate is ideal for components that require extended machining or more substantial structural elements. The saw-cut plate finish can simplify integration into projects where precise outline dimensions are needed before final shaping. The T651 temper indicates a stabilized, strengthened state through heat treatment, enhancing stiffness and durability for demanding mechanical uses.
1″ x 3.89″ x 3.89″ 7075-T651 Plate (Generic)
This generic option mirrors the compact dimensions of the other small plates, emphasizing durability and versatility for DIY metalwork. It is described as suitable for a range of mechanical applications, with emphasis on long-lasting performance and resistance to wear. The 7075-T651 composition provides high strength while remaining lighter than steel, useful for precision parts, gauges, and fixtures.
4mm × 200mm × 200mm 7075 T651 Plate
As a sheet-style plate with modest thickness, this 4mm × 200mm × 200mm option from Yodaoke suits projects requiring larger flat areas with precise milling or routing. The 7075-T651 alloy ensures high strength and stiffness. It’s framed as suitable for mechanical devices, brackets, and structural components where a balance between weight and rigidity is essential.
1.5mm × 200mm × 200mm 7075 T651 Plate
This slender 1.5mm plate from Yodaoke offers a flat, lightweight option for thin-bronze or aluminum assemblies, or as a backing plate for components requiring minimal weight and high rigidity. The 7075-T651 composition supports strong load-bearing characteristics even at small thicknesses. It’s well-suited for precision hobbies, fixtures, or equipment housings that benefit from reduced mass.
Buying Guide: Key Considerations For 7075-T651 Aluminum Plates
7075-T651 is a high-strength aluminum alloy tempered to a stable, load-bearing state. When selecting plates, consider the following:
- Strength-to-weight balance: 7075-T651 offers excellent tensile strength and stiffness, often preferred for aerospace, automotive, and high-stress mechanical parts.
- Thickness and surface finish: Thicker plates provide more support for drilling and milling, while thin sheets suit lightweight assemblies. Mill finishes may require deburring or finishing for corrosion resistance.
- Dimensions and tolerances: Ensure the length, width, and thickness align with your design drawings. Offcuts or saw-cut edges may need additional machining.
- Machinability and tooling: Although strong, 7075 can be more challenging to machine than 6061; use sharp tooling and appropriate speeds/feeds to minimize wear.
- Corrosion resistance: While aluminum resists corrosion, consider surface protection or coatings for harsh environments or prolonged exposure to moisture.
- Availability and sourcing: Look for reputable suppliers offering consistent temper (T651) and documented material certifications when necessary.
- Application fit: For structural components, verify load requirements, thermal conditions, and compatibility with other materials in the assembly.
