Description
Ultimate 7075 Plate – Superior Strength Aluminum Alloy for Critical Applications
📖 Product Overview
The 7075 plate is one of the strongest and most versatile aluminum alloys available in the commercial market today. Known for its high strength-to-weight ratio, exceptional fatigue resistance, and excellent machinability, it is widely used in demanding industries where both mechanical performance and structural reliability are essential.
Manufactured primarily from aluminum with the addition of zinc as the primary alloying element, the 7075 aluminum plate exhibits superior mechanical properties that outperform many other aluminum alloys, particularly in aerospace and defense applications.
Originally developed for the aerospace sector, this aerospace grade 7075 plate has since found its way into marine, automotive, sports, and tooling applications, thanks to its unique combination of lightness and strength. In the T6 temper, it provides ultimate tensile strength that rivals certain steels, while remaining far lighter and easier to machine.
🧪 Chemical Composition (ASTM B209 Standard)
| Element | Content (%) |
|---|---|
| Aluminum (Al) | Balance |
| Zinc (Zn) | 5.1 – 6.1 |
| Magnesium (Mg) | 2.1 – 2.9 |
| Copper (Cu) | 1.2 – 2.0 |
| Chromium (Cr) | 0.18 – 0.28 |
| Iron (Fe) | ≤ 0.50 |
| Silicon (Si) | ≤ 0.40 |
| Manganese (Mn) | ≤ 0.30 |
| Titanium (Ti) | ≤ 0.20 |
| Other (Each) | ≤ 0.05 |
| Other (Total) | ≤ 0.15 |
This precise balance of alloying elements gives the 7075 alloy plate its exceptional combination of strength, hardness, and corrosion resistance.
⚙ Mechanical Properties – 7075-T6 Plate
| Property | Typical Value |
|---|---|
| Tensile Strength | 572 MPa (83,000 psi) |
| Yield Strength | 503 MPa (73,000 psi) |
| Elongation at Break | 11% |
| Brinell Hardness | 150 HB |
| Density | 2.81 g/cm³ |
| Modulus of Elasticity | 71.7 GPa |
| Shear Strength | 331 MPa (48,000 psi) |
| Fatigue Strength | 159 MPa (23,000 psi) |
These values make the 7075 t6 plate particularly suitable for applications where both high strength and lightweight materials are required.
🔥 Heat Treatment & Tempers
The 7075 aluminum plate is available in several tempers, with T6 and T651 being the most common:
-
T6 Temper – Solution heat-treated and artificially aged for maximum strength.
-
T651 Temper – Similar to T6 but stress-relieved by stretching to minimize distortion during machining.
The heat treatment process plays a vital role in defining the mechanical properties of the aerospace grade 7075 plate, ensuring it performs consistently in high-stress environments.
