2017 Aluminum (UNS A92017) is a good-to-machine material that we run regularly for export customers. It has a density of 2.79 g/cm3, a tensile strength of 427 MPa and a typical hardness of HB 105. Those numbers make it the right choice for rivets and fasteners and screwed parts, and a poor choice when cost or corrosion resistance matters more than mechanical performance.
On our machines we hold +/-0.01 mm on turned and milled features and reach Ra 0.8 um where the drawing calls for it. Standard lead time for 2017 Aluminum parts is 3-7 working days, including material procurement, machining and any finishing operation you specify.
2017 Aluminum: key properties
| Property | Value |
|---|---|
| UNS / designation | A92017 |
| Density | 2.79 g/cm3 |
| Tensile strength | 427 MPa |
| Hardness | HB 105 |
| Machinability | Good |
| Suggested cutting speed (carbide) | 300-500 m/min |
| Relative material cost | 3 of 5 |
Machining 2017 Aluminum: what to plan for
- Poor corrosion resistance
- Being replaced by 2024
- Limited supply
Cutting speed for 2017 Aluminum with carbide tooling sits around 300-500 m/min. Going faster burns the edge; going much slower causes rubbing and a poor surface. Air blast or flood coolant both work, but chip evacuation must be positive. If your part has thin walls or a lot of stock to remove, say so in the RFQ — we plan roughing, stress relief and finishing as separate operations when the geometry demands it.
Parts we machine in 2017 Aluminum
- Rivets and fasteners
- Screwed parts
- Aircraft fittings
Most 2017 Aluminum work arrives as 2D drawings with a mix of critical and non-critical features. Loosening tolerance on the non-critical ones is the fastest way to cut cost, and we will tell you which features those are before we quote.

| Minimum wall thickness | 0.8 mm (aluminium) / 1.0 mm (steel and stainless) |
| Typical lead time | 3-7 working days |
| Prototype quantity | 1 piece |
| Production quantity | 10 to 50,000 pieces |
Frequently asked questions
What is the lead time for 2017 Aluminum parts?
Standard is 3-7 working days from drawing release, assuming the material is in stock. Exotic grades and cast forms can add 5 to 10 days. Finishing such as anodizing or plating adds 3 to 5 days.
What tolerance can you hold in 2017 Aluminum?
+/-0.01 mm is routine on turned and milled features. Tighter than that is possible on specific features by grinding or lapping, but it is quoted separately because it changes the process.
Do you keep 2017 Aluminum in stock?
We hold common sizes of 2017 Aluminum and buy mill-certified stock for everything else. Material certificates are supplied with the parts on request.
Can you supply 2017 Aluminum parts with a certificate of conformity?
Yes. We issue a dimensional report, a material certificate and a certificate of conformity as standard for production orders, and full PPAP or AS9102 paperwork when the programme requires it.
