Aluminum 7075-T6
Stronger aluminum alloy with superior strength-to-weight ratio after heat treatment, ideal for CNC machined parts requiring high strength.
Chemical Composition Of Aluminum 7075-T6
7075 aluminium alloy (AA7075) is an aluminium alloy with zinc as the primary alloying element. It boasts excellent mechanical properties, showcasing flexibility, high strength, toughness, and fatigue resistance. However, microsegregation makes it more susceptible to embrittlement than many other aluminium alloys.
XTJ also offers significantly better corrosion resistance than the 2000 series alloys. This alloy is one of the most commonly used aluminium alloys for highly stressed structural applications and has been extensively utilized in aircraft structural parts.
| Composición química | Proportions | Role of Each Element |
|---|---|---|
| Aluminum (Al) | 87.1% – 91.4% | The base metal that gives the alloy its lightweight properties. |
| Zinc | 5.1% – 6.1% | A primary alloying element that increases strength through precipitation hardening. Also improves corrosion resistance. |
| Magnesio | 2.1% – 2.9% | A key alloying element that increases strength through solid solution strengthening. |
| Cobre | 1.2% – 2.0% | Another major alloying element that increases strength through precipitation hardening. |
| cURL Too many subrequests. | Max 0.5% | An impurity that decreases ductility and fracture toughness. Kept to a minimum. |
| Silicon | Max 0.4% | A natural impurity that increases fluidity during casting. Restricted to limit its negative effect on corrosion resistance. |
| Manganese | Max 0.3% | Added to control the grain structure during solidification. Improves strength without reducing ductility. |
| Chromium | 0.18% – 0.28% | Added for improved stress corrosion cracking resistance. Also contributes to strength. |
| Titanio | Max 0.2% | Added to refine the grain size, which increases toughness and ductility. |
| Zirconium | 0.08% – 0.15% | Improves grain structure control and recrystallization resistance when added with chromium. |
The T6 heat treatment involves solution heat treating, quenching, and aging to achieve optimal strength.
