2017 is one of the original heat treatable aluminum alloys and remains in use for rivets, fittings and machined structural hardware. It offers high strength in the T4 temper with good machinability.
Rivet stock is a classic application, where the alloy is driven shortly after solution treatment before natural aging raises its strength.
Stocked as bar, rod and plate.

Why engineers specify 2017
- High strength in the naturally aged T4 temper
- Good machinability
- Established rivet and fitting material
- Readily available in bar and rod
Nominal chemistry
Percent by weight, nominal composition per the governing specification. The mill test report for your heat is the controlling document.
Typical mechanical properties
| Condition | Tensile strength | Yield strength | Elongation | Hardness |
|---|---|---|---|---|
| T4 / T451 | ~62 ksi | ~40 ksi | ~15% | - |
Typical published values for reference only, not for design. Properties vary with section size, product form and processing. Order to the specification and condition your drawing requires.
Typical applications
- Rivets and fasteners
- Machined fittings
- Structural hardware
- General engineering parts
Fabrication notes
Machining
Machines rapidly with sharp, polished, high rake tooling and high surface speeds. Heat treatable alloys cut cleanest in the T temper. Thick plate benefits from stress relieved tempers to limit movement when large volumes of material are removed.
Welding
Weldability varies by series. The 5xxx and 6xxx alloys weld readily with 4043 or 5356 filler; the 2xxx and 7xxx aerospace alloys are normally joined mechanically or by friction stir and specialized processes rather than fusion welding.
Forming
Form in the annealed or freshly solution treated condition where the temper allows, then age to final strength. Bend radii should follow the temper and thickness in the governing specification.

2017 frequently asked questions
What is 2017?
2017 is one of the original heat treatable aluminum alloys and remains in use for rivets, fittings and machined structural hardware. It offers high strength in the T4 temper with good machinability.
What forms is 2017 available in?
We supply 2017 in bar, coil, extrusion, plate, profile, rod, sheet, tube. Custom sizes are converted from billet, and we can provide saw cut, waterjet or near net blanks so material arrives closer to your finished part.
What is the UNS or equivalent designation for 2017?
2017 is designated UNS A92017. If your drawing calls out an obsolete or foreign designation we can cross reference it and confirm the equivalent before you order.
What specifications can 2017 be supplied to?
Commonly ordered specifications include AMS 4118, ASTM B211, UNS A92017. Material is released to the specification and condition on your purchase order, with mill test reports supplied as standard.
What conditions can 2017 be ordered in?
We can supply T4 / T451. If our stock is not already in the condition you need, we can quote it with the heat treatment performed before shipment.
Can you cut 2017 to size?
Yes. Saw cutting, waterjet, laser and shearing are available, along with trepanning, gun drilling, lathe turning and CNC machining, so you can order blanks or rough machined pieces rather than full lengths.
Do you provide test reports and additional testing on 2017?
Every order ships with mill test reports and heat traceability. If your print calls for ultrasonic inspection, penetrant dye, magnetic particle, chemical assay, micrography, hardness or mechanical testing and our stock does not already carry it, we can quote the material with that work performed.
Can 2017 be supplied to DFARS domestic melt requirements?
Tell us at quote stage if the order is DFARS or domestic melt restricted and we will confirm availability against that requirement before you commit.
What do you need to quote 2017?
Grade, form, dimensions, quantity, specification and condition, plus any testing or certification requirements and the date you need it. Send a drawing if you have one. Quotes are typically ready within 24 hours.
How does 2017 compare with 2024?
Higher strength and much wider aerospace usage.
