Aircraft Rivet Grade Alloy

2017-T4 Aerospace Fastener Grade Round Aluminum Bar
The 2017-T4 round aluminum bar is a copper-alloyed aerospace-grade product specifically engineered for manufacturing high-strength mechanical fasteners used in aircraft structural assembly. Also known by its European designation AlCu4MgSi, this alloy contains approximately 4% copper as its primary alloying element, which significantly improves shear strength and machinability compared to standard aluminum-magnesium-silicon alloys.
The T4 temper is achieved through solution heat treatment followed by natural aging at room temperature, resulting in a material that combines high mechanical strength with the ductility required for cold heading and thread rolling operations. This alloy is the industry standard for producing solid aluminum rivets, Hi-Lok type fasteners, lockbolts, and other aerospace structural joining components where reliable shear performance and corrosion resistance are critical requirements.
Conforming to AMS 4118 and ASTM B211 specifications, 2017-T4 bars undergo rigorous quality testing including ultrasonic inspection, conductivity verification, and mechanical property validation to ensure compliance with aerospace industry standards.
Key Features
  • Superior Shear Strength Minimum shear strength of 235 MPa ensures reliable load transfer in riveted and bolted aircraft structural joints, preventing fastener failure under dynamic flight loads and vibration.
  • Copper-Alloyed Composition The 4% copper content provides approximately 25% higher strength than 6061-T6 alloy while maintaining adequate corrosion resistance for protected aerospace applications.
  • Excellent Cold Formability T4 temper exhibits good ductility with minimum 12% elongation, enabling cold heading, upset forging, and thread rolling operations without cracking or requiring intermediate annealing.
  • Consistent Machinability The copper addition improves chip-breaking characteristics during automatic lathe turning operations, enabling high-speed production of precision fastener blanks with excellent surface finish.
  • Aerospace Certified Full material traceability per AMS 4118 with mill test certificates documenting chemical analysis, tensile properties, shear strength, and ultrasonic inspection results for every production lot.
  • Natural Age Hardening The T4 temper continues to develop strength gradually at room temperature after solution treatment, reaching stable mechanical properties within 4-7 days for predictable manufacturing performance.

Applications
2017-T4 round aluminum bars are predominantly utilized in the aerospace fastener manufacturing industry for the production of critical structural joining components. Solid rivets manufactured from this alloy are installed extensively in aircraft fuselage skin panels, wing rib attachments, and stringer-to-frame connections where thousands of fasteners must reliably transfer structural loads throughout the service life of the aircraft.
The alloy is also commonly specified for the production of Hi-Lok pins, lockbolts, and blind fasteners used in commercial airframes including Boeing 737, Airbus A320, and regional jet platforms. Beyond aerospace applications, 2017-T4 bars are employed in high-performance automotive fasteners for motorsport chassis assembly, vehicle armor attachment systems, and precision mechanical assemblies where high shear strength and light weight are simultaneously required.
Fastener manufacturers typically cold-head the material into rivet blanks or bolt preforms, then perform thread rolling, shank machining, and surface treatment processes including alodine chemical conversion coating or sulfuric acid anodizing to enhance corrosion protection.
Packaging & Quality Assurance
Each 2017-T4 round aluminum bar receives a protective anti-rust oil coating and is individually wrapped in VCI (Volatile Corrosion Inhibitor) paper to prevent surface oxidation during storage and transit. Bars are packed in fumigation-free plywood cases meeting ISPM 15 international phytosanitary standards, with interleaving separators preventing surface contact damage between individual bars.
Every shipment is accompanied by an EN 10204 3.1 mill test certificate documenting full chemical composition analysis, tensile test results, shear strength values, hardness measurements, and ultrasonic inspection reports. Our quality management system maintains full material traceability from certified aluminum billet source through extrusion, heat treatment, straightening, and final inspection stages.
Batch identification numbers are permanently marked on each bar end for complete quality chain documentation. Standard stock diameters from 6mm to 80mm ship within 5 working days, while custom sizes and special tolerance orders are fulfilled within 15-25 working days. We also offer value-added processing services including precision cut-to-length, chamfering, and centerless grinding upon request for customers requiring ready-to-machine bar stock.
