5052-H32 Aluminum (UNS A95052) is a moderate-to-machine material that we run regularly for export customers. It has a density of 2.68 g/cm3, a tensile strength of 228 MPa and a typical hardness of HB 60. Those numbers make it the right choice for marine panels and fuel tanks, and a poor choice when cost or corrosion resistance matters more than mechanical performance.
On our machines we hold +/-0.02 mm on turned and milled features and reach Ra 0.8 um where the drawing calls for it. Standard lead time for 5052-H32 Aluminum parts is 3-7 working days, including material procurement, machining and any finishing operation you specify.
5052-H32 Aluminum: key properties
| Property | Value |
|---|---|
| UNS / designation | A95052 |
| Density | 2.68 g/cm3 |
| Tensile strength | 228 MPa |
| Hardness | HB 60 |
| Machinability | Moderate |
| Suggested cutting speed (carbide) | 200-400 m/min |
| Relative material cost | 2 of 5 |
Machining 5052-H32 Aluminum: what to plan for
- Gummy chips on deep pockets
- Cannot be heat treated
- Poor anodize depth
Cutting speed for 5052-H32 Aluminum with carbide tooling sits around 200-400 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 5052-H32 Aluminum
- Marine panels
- Fuel tanks
- Sheet-metal housings
- Bent brackets
Most 5052-H32 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.

Frequently asked questions
What is the lead time for 5052-H32 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 5052-H32 Aluminum?
+/-0.02 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 5052-H32 Aluminum in stock?
We hold common sizes of 5052-H32 Aluminum and buy mill-certified stock for everything else. Material certificates are supplied with the parts on request.
Can you supply 5052-H32 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.
