Product Description
As a leading manufacturer with over 20 years of expertise in aerospace materials, we specialize in producing 7xxx series high-strength aluminum strips tailored for critical aerospace applications. Engineered with premium Al-Zn-Mg-Cu alloys (notably 7075, 7050, and 7175), these strips strike an exceptional balance between ultra-high tensile strength (up to 503 MPa) and lightweight properties (density ≈2.81 g/cm³), strictly adhering to aerospace standards including AMS 4049, ASTM B209, and EN 485. Our production process integrates multi-pass precision rolling (up to 12 rolling stages) and T6/T73 heat treatment cycles to eliminate internal stresses, ensuring consistent mechanical performance across entire batches. With customizable thicknesses (0.5–5 mm, with 0.05 mm incremental adjustments) and diverse surface finishes (mill, anodized, or painted), we accommodate the unique design requirements of aircraft manufacturers and defense contractors worldwide.

Ultra-High Strength-to-Weight Ratio: Achieved through precise alloying and heat treatment, making them ideal for aircraft structural components (e.g., wing spars, fuselage frames) where both durability and fuel efficiency are critical.
Enhanced Corrosion Resistance: Protected by 0.02–0.05 mm alclad layers (1050 aluminum) or specialized corrosion-resistant coatings (e.g., trivalent chromate) to withstand extreme aerospace environments, including high humidity and temperature fluctuations.
Micron-Level Precision Manufacturing: Utilizing advanced laser thickness gauges, our strips achieve ±0.01 mm thickness tolerance and flatness of ≤0.5 mm/m, ensuring seamless integration into complex assemblies with minimal post-processing.
Tailored Customization Options:
Alloy Composition: Adjust Zn (5.1–6.1%), Mg (2.1–2.9%), and Cu (1.2–2.0%) levels to meet specific load-bearing and fatigue resistance requirements.
Surface Treatments: Anodizing (2–25 μm thickness), powder coating (40–80 μm), or PTFE coatings for enhanced wear resistance and dielectric properties.
Aircraft Structures: Wing ribs, landing gear components, engine mounts, and stringers for commercial airliners and military jets.
Spacecraft: Lightweight payload panels, high-stress brackets, and satellite structural frames.
Defense: Armor plating for military vehicles, missile guidance components, and tactical equipment housings.
High-Performance Automotive: Racing car chassis frames, suspension arms, and lightweight body panels.
Q: What is the minimum order quantity?
A: MOQ starts at 1 ton, with flexible pricing tiers for bulk orders exceeding 10 tons.
Q: Can you provide material certification?
A: Yes, we offer EN 10204 3.1/3.2 certificates, material traceability reports, and third-party testing reports from SGS or TÜV.
Q: How long is the lead time?
A: Typically 2–4 weeks for standard orders; expedited production (1–2 weeks) is available for urgent requests with a 20% premium.
Q: Do you offer pre-machined strips?
A: Yes, we provide CNC cutting, drilling, and deburring services to deliver ready-to-assemble components.
Pair with our aerospace-grade aluminum fasteners (e.g., 2024-T3 rivets, 7075-T6 bolts) and epoxy-based structural adhesives (capable of withstanding -55°C to 120°C) for optimal joint performance. For quality assurance, our ISRA PARSYTEC surface inspection systems detect micro-defects (≥5 μm) in real time during production.
