What are the 7xxx Series Aluminum Alloys (Al-Zn-Mg-Cu)?
The 7xxx Series Aluminum Alloys are wrought aluminum alloys distinguished by having zinc (Zn) as the principal alloying element, combined with magnesium (Mg) and often copper (Cu) . The combination of zinc and magnesium forms the principal hardening agent (MgZn2) when the alloy is subjected to aging (precipitation) heat treatment . The addition of copper further improves strength.
These alloys are renowned for achieving the highest mechanical strengths of all wrought aluminum alloys, even surpassing many steels in strength-to-weight ratio. However, their corrosion resistance can be challenging, especially stress corrosion cracking, so they are often used with protective coatings such as Alclad (layers of pure or low-alloy aluminum over a high-strength core). The most well-known and widely used alloy in this series is 7075 .
Key Properties of 7xxx Series Aluminum Alloys (Al-Zn-Mg-Cu):
- Maximum Tensile Strength: 7xxx alloys achieve the highest strengths of any aluminum alloy, comparable to some low-alloy steels.
- High Fatigue Resistance: Essential for components subjected to cyclic loads.
- Heat Treatment Hardenable: Their properties are significantly optimized by artificial aging (conditions T6, T73, T76, etc.).
- Good Machinability: Relatively easy to machine.
- Lower Corrosion Resistance: They are more susceptible to corrosion than other aluminum types, especially stress corrosion cracking and intergranular corrosion. They often require surface protection.
- Limited Weldability: Welding is generally not recommended for critical structural applications due to loss of strength in the heat affected zone and susceptibility to embrittlement.
Features and Specifications of 7xxx Series Aluminum Alloys:
We market 7xxx Series Aluminum Alloys in a wide variety of grades and formats, adapting to the demands of high-tech and high-performance industries. Common grades include:
- 7050: An advanced alloy with an excellent combination of strength, toughness, and stress corrosion resistance, developed for high-strength aerospace applications.
- 7075: The workhorse of the 7xxx series, widely used in the aerospace industry. It offers exceptional strength and a good strength-to-weight ratio. It is often supplied as Alclad or in conditions that improve stress corrosion resistance (e.g., T7351).
- 7049, 7150, 7475: Other grades with variations in property balance for very specific applications.
- Chemical Composition: Specific contents of zinc (Zn), magnesium (Mg), copper (Cu), and often chromium (Cr), zircon (Zr), or titanium (Ti), in addition to aluminum (Al). Percentages vary by grade to optimize properties.
- Condition/Temper: Mechanical properties are achieved through very specific heat treatments, indicated by the letter “T” followed by numbers and subscripts that define the aging process (e.g., T6, T73, T7351, T7651). “T7x” conditions offer improved resistance to stress corrosion cracking at the expense of a slight reduction in ultimate strength.
- Format:
- Sheets and Plates: For aircraft skins, wing and fuselage structural components.
- Bars: Round, square, hexagonal, for high-strength machined components (e.g., landing gear, fasteners).
- Extruded Profiles: Complex shapes for aerospace and military structures.
- Forgings: Critical components such as landing gear, structural ribs.
- Surface Finish: Can be supplied raw, anodized or, very commonly, with Alclad coatings for corrosion protection.
