What Is 2017 Aluminum?

2017 aluminum alloy (UNS A92017, EN AW-2017) is a copper-based, heat-treatable alloy in the 2xxx series. Its nominal composition — approximately 3.5–4.5% Cu, 0.4–1.0% Mn, 0.4–0.8% Mg, and 0.2–0.8% Si — gives it a combination of strength and machinability that makes it a practical choice for forged and machined structural parts.

In the annealed (O) condition, 2017 exhibits good ductility for cold-forming operations such as riveting. After solution heat treatment and natural aging (T4), it develops tensile strength up to approximately 390 MPa — comparable to many higher-strength aerospace alloys, though with somewhat lower corrosion resistance than 2xxx alloys containing higher magnesium.

2017 is the direct US equivalent of the Chinese 2A11 (GB/T 3190) and Russian D1 alloy designations. It is sometimes referred to as AlCu4MgSi under the ISO designation system.

Temper Selection Guide

Choosing the right temper for 2017 depends on the balance between formability and strength your application demands:

• O (recozido) — Maximum ductility. Best for cold-forming operations such as riveting, bending, or heading. Strength develops later through natural aging after forming.
• T3 / T4 — Solution heat-treated and naturally aged. Peak strength for 2017. Ideal for machined structural components, fasteners, and aerospace parts that do not require welding.
• T351 — Solution heat-treated, stress-relieved by stretching, then naturally aged. Provides dimensional stability during machining — recommended for precision-machined plate and bar.
• T42 / T451 — User heat-treated variants (solution treated from O temper by the purchaser). Useful when you need to form in O temper first and then develop full strength on-site.

Observação: 2017 is not recommended for welding. If weldability is a priority, consider 5052 or 6061 as alternatives.

Principais características

Strength & Machinability

With Cu as the primary alloying element (~4%), 2017 achieves high strength in the T4 temper (UTS ~390 MPa) while maintaining good machinability. It machines readily with standard CNC tooling and produces clean chips — a practical advantage over softer alloys in high-volume machining runs.

Resistência à corrosão

2017 has moderate corrosion resistance — adequate for many indoor and protected structural applications, but less suitable than 5xxx or 6xxx alloys for prolonged exposure to marine or industrial atmospheres. Where corrosion is a concern, consider protective surface treatments (anodizing, painting) or switching to a 5xxx-series alloy.

Formabilidade

In the O temper, 2017 offers good cold formability — it can be bent, headed, and riveted with standard tooling. After heat treatment (T3/T4), formability drops significantly; most forming should be completed before solution treatment.

Soldabilidade

2017 is not recommended for arc welding. The high copper content promotes hot cracking and reduces weld joint strength. Resistance welding (spot, seam) is possible with appropriate parameters. If welding is required, 5052, 5083, or 6061 are better choices.

Aplicativos

2017 aluminum alloy is specified in industries that demand high strength from a machinable, heat-treatable material:

• Aeroespacial: Rivets, fasteners, brackets, and structural fittings where T4 strength and O-temper formability are both exploited in the manufacturing sequence
• Automotivo: Machined engine components, steering knuckles, and suspension brackets
• General engineering: CNC-machined housings, shafts, and precision hardware
• Fastener manufacturing: Cold-headed rivets and bolts (formed in O, aged to T4)
• Military & defense: Structural components in vehicle and equipment assemblies

Processing & Surface Finish Notes

2017 alloy responds well to standard aluminum processing methods:

• CNC machining: Excellent — one of 2017’s primary advantages over softer alloys. Clean chip formation, good dimensional stability in T351 temper.
• Cold forming: Good in O temper (bending, heading, riveting). Not recommended in heat-treated tempers.
• Surface treatments: Anodizing is achievable but produces a darker finish compared to 6xxx alloys. Mill finish, polishing, and powder coating are all available.
• Heat treatment: Solution treat at ~500–510 °C, quench, natural age at room temperature. Artificial aging (T6-type) is not commonly specified for 2017.

2017 Aluminum FAQ

What is the difference between 2017 and 2024?

Both are 2xxx-series Cu-based alloys, but 2024 contains higher Mg (~1.5%) and achieves higher strength (~470 MPa UTS in T4). 2017 has slightly lower strength but better formability in the O temper, making it preferred for rivets and cold-headed fasteners.

Can 2017 aluminum be welded?

2017 is not recommended for arc welding due to hot-cracking susceptibility from its high Cu content. Resistance welding (spot/seam) may be used with controlled parameters. For weldable alternatives in similar strength ranges, consider 6061-T6 or 5083.

What temper should I specify for machined parts?

T351 is recommended for precision-machined plate and bar — the stress-relief stretch after quenching provides dimensional stability during machining. T4 is acceptable when dimensional tolerance requirements are less stringent.

Is 2017 the same as 2A11?

Yes. 2017 (AA/UNS designation) and 2A11 (Chinese GB/T 3190 designation) are equivalent alloys with the same nominal composition. The Russian equivalent is D1.

What surface finishes are available for 2017?

Mill finish, polished, anodized (darker tone than 6xxx alloys), and powder-coated. Anodizing quality is acceptable but not as bright as 6061 or 6063.
