Alliage d'aluminium 2117

2117 aluminum is a copper-based 2xxx series alloy best known as the standard rivet alloy in aerospace construction. Its combination of moderate strength, excellent ductility, and reliable shear performance makes it the preferred choice for structural rivets and fasteners. Linsy supplies 2117 in bar, wire, sheet, and tube — all backed by mill test certificates.

What Is 2117 Aluminum Alloy?

2117 aluminum (also designated EN AW-2117 / UNS A92117) is a low-copper 2xxx series alloy containing approximately 2.2–3.0% copper with small additions of silicon, magnesium, and manganese. It is specifically developed for rivet and fastener applications where a balance of strength and ductility is essential.

2117 is the standard alloy for solid rivets in aircraft construction — it provides adequate shear strength while maintaining enough ductility for cold heading and rivet driving without cracking. It is also used for general-purpose fasteners, cotter pins, and cold-formed hardware.

In the T4 temper (solution heat-treated and naturally aged), 2117 achieves its best combination of shear strength and ductility. This makes it the default rivet material in most aerospace specifications.

Guide de sélection des tempéraments

T4 Temper — Standard Rivet Temper

T4 (solution heat-treated and naturally aged) is the default temper for 2117 rivet wire and bar. It provides the optimal balance of shear strength and ductility for cold-heading and rivet-driving operations. Most aerospace rivet specifications require 2117-T4.

T42 Temper — Controlled Properties

T42 is 2117 that has been solution heat-treated and naturally aged to meet specific mechanical property ranges negotiated between purchaser and supplier. Used when tighter control of shear or tensile values is required.

T3 Temper — Cold-Worked + Natural Aging

T3 provides higher ductility with slightly lower strength — suitable for applications requiring more forming before final aging.

Tempérer Meilleur pour Key Advantage
T4 Standard rivets, structural fasteners Best shear/ductility balance for rivet driving
T42 Spec-controlled rivets Tight property ranges per purchaser agreement
T3 Formed parts needing extra ductility Higher elongation before aging

Caractéristiques principales

Excellent Rivet Performance

2117-T4 is the industry-standard rivet alloy. Its shear strength (~185–210 MPa) is sufficient for structural joints, while its elongation (15–22%) ensures reliable cold heading and driving without cracking — the two essential properties for rivet performance.

Good Ductility & Cold Formability

The relatively low copper content (2.2–3.0%) gives 2117 better ductility than 2024 or 2014. This makes it suitable for heading, upsetting, and cold-forming operations common in fastener manufacturing.

Résistance modérée

2117 is not a high-strength structural alloy. Its tensile strength (295–340 MPa in T4) is adequate for shear-loaded joints but insufficient for primary structural members. For high-strength applications, use 2024 or 7075 instead.

Résistance à la corrosion

2117 has moderate corrosion resistance — better than 2024 but not suitable for marine environments without protection. In aerospace construction, 2117 rivets are typically used with Alclad 2024 sheet, where the rivet and surrounding skin form a compatible dissimilar-metal joint.

Applications

2117 aluminum is used wherever rivet and fastener performance is critical:

  • Aerospace rivets: Standard solid rivets (MS20426, AN470 series) for aircraft skin and structural joints
  • Automotive fasteners: Cotter pins, split pins, and formed hardware
  • General fasteners: Cold-headed bolts, screws, and rivets for light structural applications
  • Usinage CNC : Precision-turned bushings, sleeves, and fittings
  • Structural hardware: Clevis pins, retaining rings, and shear pins

Remarques concernant le traitement et la finition de surface

  • Cold heading: 2117-T4 is specifically designed for cold heading operations (rivet manufacturing). The alloy’s ductility allows it to be upset and formed without pre-heating.
  • Rivet driving: 2117 rivets can be driven by hand, pneumatic, or hydraulic methods. The alloy’s shear strength provides reliable joint performance after driving.
  • Usinage : Fair machinability — better than pure aluminum but not as free-cutting as 2011 or 2030. Carbide tooling recommended for production runs.
  • Soudage : Not recommended for structural welding. Gas tungsten arc (TIG) welding is possible for non-critical repair but is not a standard joining method for 2117 components.
  • Traitement thermique : Solution treatment at approximately 500–510°C, followed by natural aging. Artificial aging (T6) is rarely specified for 2117.
  • Finition de surface : Anodizing is possible; results are functional but not as cosmetically uniform as 6xxx alloys due to copper content.

2117 Aluminum FAQ

Why is 2117 used for rivets?

2117-T4 provides the right balance of shear strength (~185–210 MPa) and ductility (15–22% elongation) for cold heading and rivet driving. The alloy can be upset and formed into rivet heads without cracking, and the driven rivet provides reliable shear-load performance.

How does 2117 compare to 2017 for rivets?

2017 (AD rivet alloy) has higher shear strength but lower ductility than 2117. 2117 (A rivet alloy) is more forgiving during rivet driving and is preferred for standard structural joints. 2017 is used where higher shear strength is required.

Can 2117 rivets be used with 2024-T3 skin?

Yes. 2117-T4 rivets are commonly used with 2024-T3 and Alclad 2024-T3 sheet in aircraft construction. The dissimilar-metal potential is minimal and is addressed by design standards (MIL-HDBK-5 / MMPDS).

Is 2117 weldable?

Not recommended for structural welding. TIG welding is possible for non-critical repair, but riveting or mechanical fastening is the standard joining method for 2117 components.

What is the difference between T4 and T42?

T42 is 2117 that has been heat-treated to meet specific mechanical property ranges negotiated between purchaser and supplier, rather than the standard T4 minimums. It provides tighter control of properties for critical applications.
