Product Description

7075 Aluminium (AlZnMgCu1.5), under the Austrian NORM standard, is a premier high-strength alloy. It belongs to the 7000 series, where zinc is the primary alloying element, providing mechanical properties that rival many structural steels.

1. Key Designations and Standards

The designation AlZnMgCu1.5 is the chemical shorthand used across Europe to identify this specific high-strength chemistry.

Standard	Designation
NORM (Austria)	AlZnMgCu1.5
WNr (Germany)	3.4365
EN AW (Europe)	7075
ISO	AlZn5.5MgCu
UNS (USA)	A97075

2. Chemical Composition (Typical %)

The high strength of this alloy is derived from the precise balance of Zinc, Magnesium, and Copper, which respond exceptionally well to precipitation hardening.

Zinc (Zn): 5.10 6.10%
Magnesium (Mg): 2.10 2.90%
Copper (Cu): 1.20 2.00%
Chromium (Cr): 0.18 0.28%
Manganese (Mn): 0.30% max
Aluminium (Al): Remainder

3. Mechanical Properties by Form

The properties of 7075-T6 (Solution heat-treated and artificially aged) are the most common for industrial applications.

Property	Sheet (< 6mm)	Plate / Block (> 12mm)
Tensile Strength ( $R_m$ )	540 MPa	570 MPa
Yield Strength ( $R_{p0.2}$ )	470 MPa	500 MPa
Elongation ( $A_{50mm}$ )	8%	7%
Hardness (HB)	150	150

4. Key Engineering Characteristics

Strength-to-Weight: Exceptional. It is used to replace steel in applications where reducing mass is critical without sacrificing structural integrity.
Machinability: Excellent. It is widely considered one of the best aluminium alloys for high-speed CNC milling and turning, as it produces clean, brittle chips.
Corrosion Resistance: Poor. Due to the high copper and zinc content, it is susceptible to atmospheric corrosion and stress corrosion cracking. Surface treatments like hard-anodizing or chromating are highly recommended.
Weldability: Not Recommended. Standard fusion welding (MIG/TIG) causes significant strength loss in the heat-affected zone and creates a high risk of cracking.

5. Common Applications

Aerospace: Highly stressed structural parts, wing spars, and bulkheads.
Precision Tooling: Mold bases for plastic injection molding and blow molds.
Defense: High-performance components for military hardware and ordnance.
Mechanical Engineering: High-speed rotating parts, gears, and shafts.

6. Available Forms in NORM / EN Standards

Sheets: Available in thin gauges for skins and panels (often "Alclad" for corrosion protection).
Plates: Provided in thicknesses up to 150mm+, often in T651 temper (stress-relieved by stretching) to ensure dimensional stability after machining.
Blocks: Large forged or rolled sections used for heavy-duty tool and die manufacturing.

Unmatched Strength and Lightweight Composition

With a yield strength of 503 MPa minimum and a tensile strength of 572 MPa minimum, 7075-AlZnMgCu1.5 aluminium offers superior mechanical properties while maintaining a low density of 2.81 g/cm3. This unique combination is ideal for high-strength applications in aerospace and engineering where weight reduction is critical.

Customizable Solutions for Versatile Applications

Available in plates, blocks, and sheets with thicknesses ranging from 10mm to 250mm, this aluminium alloy can be tailored to meet specific project requirements. Custom sizing and a smooth, mill finish make it suitable for aircraft structures, high-strength components, moulds, and demanding engineering environments.

Exceptional Machinability and Performance

Engineered for precision, 7075-AlZnMgCu1.5 aluminium exhibits excellent machinability, enabling seamless fabrication and complex component design. Despite its high strength, it retains good fatigue resistance and fair thermal and electrical conductivity, supporting performance in critical applications.

FAQ's of 7075-AlZnMgCu1.5 Aluminium Plates, Blocks & Sheets (ONORM):

Q: What are the primary uses of 7075-AlZnMgCu1.5 Aluminium Plates, Blocks & Sheets (ONORM)?

A: These aluminium products are utilized in aerospace structures, defence equipment, high-load engineering components, mould manufacturing, and transportation sectors due to their high strength, low weight, and good resistance to corrosion.

Q: How does the manufacturing process ensure consistent quality for 7075 aluminium alloy plates and sheets?

A: The materials are produced to strict ONORM 7075 and international standards (AMS 4045, ASTM B209, EN AW-7075), ensuring robust mechanical strength, precise dimensions, and excellent surface finish. Stringent composition control and heat treatment (T6, T651) contribute to performance consistency.

Q: What is the machinability and weldability of this aluminium grade?

A: 7075-AlZnMgCu1.5 aluminium is known for its excellent machinability, permitting complex and precise fabrication. However, its weldability is limited and welding is generally not recommended due to the alloy's copper content, which can affect mechanical properties in the weld zone.

Q: Where can I use these aluminium plates and sheets for best results?

A: Best suited for structural components in aerospace, defence, and engineering industries, these plates and sheets perform exceptionally in environments demanding high mechanical strength and low weight. They're also favored in mould and toolmaking.

Q: When should I choose 7075 aluminium over other grades?

A: Select 7075 aluminium when your application requires maximum strength-to-weight ratio, excellent machinability, and good fatigue resistance. It is preferred for aircraft parts, high-load fittings, and structures exposed to significant mechanical stress.

Q: What are the benefits of the available tempers (T6, T651) in 7075 aluminium?

A: Tempers T6 and T651 provide enhanced mechanical properties, including higher strength, improved flatness, and better dimensional stability. This results in durable, reliable components suitable for demanding and precision-driven applications.
