The 7075 T6 aluminum forging disc is a high-strength aluminum product manufactured from 7075 aluminum alloy, with zinc as the primary alloying element. This alloy is well known for its exceptional mechanical performance, including high tensile strength, excellent toughness, good ductility, and outstanding fatigue resistance.
Compared with many other aluminum alloys, 7075 aluminum is more sensitive to embrittlement caused by microsegregation; however, it offers significantly better corrosion resistance than 2000 series aluminum alloys. Because of its superior strength-to-weight ratio, 7075 alloy is one of the most widely used materials for highly stressed structural components, especially in aircraft and aerospace applications.
At GNEE, we supply precision-forged 7075 T6 aluminum discs designed to meet strict performance and dimensional requirements for aerospace, defense, automotive, and high-performance industrial uses.
Product Description
Chemical Composition of 7075 Aluminum Alloy
(According to standard specifications)
| Alloy | Si | Fe | Cu | Mn | Mg | Cr | Zn | Ti | Al |
|---|---|---|---|---|---|---|---|---|---|
| 7075 | ≤0.4 | ≤0.5 | 1.2–2.0 | ≤0.3 | 2.1–2.9 | 0.18–0.28 | 5.1–6.1 | ≤0.2 | Balance |
The aluminum matrix is strengthened primarily through zinc, magnesium, and copper, which together provide excellent response to heat treatment and precipitation hardening.
Product Applications
The typical composition of 7075 aluminum alloy includes approximately 5.6–6.1% zinc, 2.1–2.5% magnesium, and 1.2–1.6% copper, with small amounts of silicon, iron, manganese, chromium, titanium, and other trace elements.
7075 aluminum is available in multiple tempers, including 7075-O, 7075-T6, and 7075-T651, allowing it to meet different strength, stability, and machining requirements.
Common applications of 7075 T6 aluminum forging discs include:
Aircraft fittings and structural components
Aerospace and defense parts
Gears, shafts, and worm gears
Missile and weapon system components
Regulating valve parts and precision mechanical parts
Fuse components, meter shafts, and keys
High-performance bicycle frames
All-terrain vehicle (ATV) sprockets
Due to its high fatigue resistance and strength, 7075 T6 is especially suitable for components subjected to repeated loading and extreme stress.
Product Features
Mechanical Properties of 7075-T6 Aluminum
Ultimate Tensile Strength: 510–540 MPa (74,000–78,000 psi)
Yield Strength: ≥ 430–480 MPa (63,000–69,000 psi)
Elongation at Break: 5–11%
High fatigue resistance and excellent strength-to-weight ratio
Heat Treatment Process
The T6 temper of 7075 aluminum is achieved through a controlled heat-treatment process:
Homogenization of the cast alloy at approximately 450 °C for several hours
Rapid quenching to retain alloying elements in solid solution
Artificial aging at around 120 °C for 24 hours
This process produces peak strength by forming finely dispersed η (eta) and η′ (eta prime) precipitates within the grains and along grain boundaries. These precipitates are the primary source of the alloy's exceptional strength and fatigue performance.
