5052 aluminum round bar is a non-heat-treatable 5xxx-series alloy prized for its exceptional corrosion resistance, particularly in saltwater and marine environments. Supplied in O, H32, and H34 tempers, it combines excellent formability with moderate strength and outstanding weldability. Linsy manufactures and stocks 5052 round bars in a wide range of standard and custom diameters, cut to length and backed by a Mill Test Certificate (MTC) with every order.

5052 aluminum round bar is a solid cylindrical product made from the 5052 aluminum alloy (EN AW-5052 / A95052), a non-heat-treatable 5xxx-series alloy with magnesium as its primary alloying element (2.2–2.8%). The round bar form is one of the most commonly stocked shapes for this grade, valued for its balance of corrosion resistance, formability, and moderate strength.
Unlike heat-treatable alloys such as 6061 or 7075, 5052 gains its strength through strain hardening (cold working). It is supplied in H32 and H34 tempers — stabilized tempers that retain about 1/4 and 1/2 hard cold-work, respectively — as well as the fully annealed O temper for maximum formability. This makes 5052 round bar suitable for marine hardware, fuel tank fittings, pressure vessel components, and general structural and decorative applications where corrosion resistance is critical.
Standard designations include ASTM B221, GB/T 3190, JIS H4000oraz AMS 4015 (sheet equivalent). Linsy supplies 5052 round bars to these specifications with full traceability documentation.

The table below shows the nominal chemical composition of 5052 aluminum per GB/T 3190 and ASTM standards. Magnesium is the primary alloying element, responsible for the alloy’s strength and corrosion resistance. Chromium refines the grain structure and improves stress-corrosion cracking resistance.

| Si | 0,25 maks |
| Fe | maks. 0,40 |
| Cu | 0,10 maks |
| Mn | 0,10 maks |
| Mg | 2.2 – 2.8 |
| Cr | 0.15 – 0.35 |
| Zn | 0,10 maks |
| Al | Równowaga |
Because 5052 is a non-heat-treatable alloy, its mechanical properties depend on the temper — specifically the degree of cold work applied. The values below are typical for 5052 round bar in the most common tempers. Actual properties may vary with bar diameter and production lot; certified values are provided on the MTC with each shipment.
| Nieruchomość | O (wyżarzony) | H32 (1/4 twardy) | H34 (1/2 twardy) |
|---|---|---|---|
| Maksymalna wytrzymałość na rozciąganie (MPa) | 175 – 215 | 205 – 240 | 230 – 270 |
| Granica plastyczności (MPa) | 65 – 80 | 130 – 155 | 150 – 180 |
| Wydłużenie przy zerwaniu (%) | 20 – 25 | 12 – 18 | 10 – 14 |
| Hardness (Brinell, HB) | ~47 | ~60 | ~68 |
The original source listed a single tensile strength (210 MPa) and yield strength (135 MPa) without specifying the temper. These values are consistent with H32 typical properties. The ranges above reflect published industry data; certified lot-specific values accompany every shipment.
Choosing the right temper for 5052 aluminum round bar depends on the balance between formability and strength required by your application:
The softest condition, offering maximum formability and ductility. Best for applications requiring severe bending, forming, or drawing. Strength is the lowest of the three common tempers.
Strain-hardened and then stabilized to maintain properties over time. Offers a good balance of strength and formability — the most popular choice for general-purpose round bar applications including marine fittings and structural components.
Higher cold-work content than H32, giving greater strength and hardness at the expense of some ductility. Suitable for components that require higher load-bearing capacity but less forming during fabrication.

5052 aluminum offers outstanding resistance to saltwater, marine atmospheres, and a wide range of chemicals. The magnesium content forms a stable, self-healing oxide layer that protects the surface even in harsh environments. This makes 5052 round bar a preferred material for marine hardware, pump shafts, and chemical processing equipment.
As a non-heat-treatable alloy, 5052 can be readily bent, formed, and machined. The O temper offers the highest formability, while H32 and H34 still permit moderate cold forming. The alloy machines cleanly with appropriate speeds and feeds.
5052 welds readily using gas tungsten arc welding (GTAW/TIG), gas metal arc welding (GMAW/MIG), and resistance welding. Weld joint efficiency is high, and the heat-affected zone retains good corrosion resistance. 5052 filler wire (ER5356 or ER5554) is typically recommended.
While not as strong as 2xxx or 7xxx series alloys, 5052 provides adequate strength for many structural and mechanical applications. Its strength-to-weight ratio is competitive for corrosion-critical service where higher-strength alloys would require protective coatings.

H32 is a 1/4-hard stabilized temper offering a balance of strength and formability. H34 is a 1/2-hard stabilized temper with higher tensile and yield strength but reduced ductility. Choose H32 for general-purpose applications and moderate forming; choose H34 when higher strength is the priority.
Yes. 5052 has excellent weldability using TIG (GTAW) and MIG (GMAW) processes. ER5356 or ER5554 filler wire is recommended. The weld zone retains good corrosion resistance, making 5052 suitable for welded structures in marine and chemical environments.
