1. What Is Aluminium 5052 Sheet?
Aluminium 5052 is a wrought aluminium-magnesium alloy, non-heat-treatable, known for combining moderate-to-high strength with outstanding resistance to corrosion particularly in marine and humid environments. Unlike pure aluminium sheets (1100, 1050) which are soft and mainly decorative, 5052 gains its strength through magnesium and chromium alloying, followed by strain hardening (cold working), rather than heat treatment.
This makes 5052 sheet the go-to choice wherever a fabricator needs a material that is:
- Strong enough to hold shape under vibration and stress
- Light enough to reduce overall product weight
- Corrosion-resistant enough to survive outdoor, marine, or chemical exposure
- Easy enough to bend, roll, and weld without cracking
As a trusted Aluminium Sheet 5052 Supplier, HHhub sources and stocks 5052 sheets in a wide range of thicknesses and tempers so that fabrication units across Delhi NCR never have to wait on production timelines.
Chemical Composition of Aluminium Alloy 5052
Understanding the composition of 5052 helps buyers verify mill test certificates (MTC) and confirm that the material meets ASTM B209 / ASME SB209 standards. Genuine 5052 sheet from a certified Aluminium 5052 Sheet Manufacturer should fall within the following limits:
| Element | Composition (%) | Role in the Alloy |
| Aluminium (Al) | Remainder (~95–97.7%) | Base metal; provides lightweight structure |
| Magnesium (Mg) | 2.2 – 2.8% | Primary strengthening element; boosts corrosion resistance |
| Chromium (Cr) | 0.15 – 0.35% | Controls grain structure; improves stress-corrosion resistance |
| Iron (Fe) | ≤ 0.40% | Impurity; controlled to avoid brittleness |
| Silicon (Si) | ≤ 0.25% | Impurity; affects strength and machinability |
| Copper (Cu) | ≤ 0.10% | Minor impurity |
| Manganese (Mn) | ≤ 0.10% | Minor impurity |
| Zinc (Zn) | ≤ 0.10% | Minor impurity |
| Other (each/total) | ≤ 0.05% / 0.15% | Trace elements |
At HHhub, every batch of aluminium sheet is checked against this composition range before dispatch, and mill test certificates are shared with clients on request, a practice not every trader in the Delhi market follows.
Mechanical & Physical Properties
The temper of a 5052 sheet (O, H32, H34, H36, H38) determines its final strength and formability. Below is a quick reference table used commonly by design engineers and fabricators.
| Property | O (Annealed) | H32 | H34 | H36 | H38 |
| Tensile Strength (MPa) | 170–215 | 210–260 | 230–280 | 250–305 | 270–320 |
| Yield Strength (MPa, min) | 65 | 145 | 175 | 195 | 215 |
| Elongation (% in 50mm) | 25–30 | 12–18 | 10–14 | 8–10 | 7–8 |
| Hardness (Brinell, approx.) | 47 | 60 | 68 | 73 | 77 |
| Density | 2.68 g/cm³ (constant across all tempers) | ||||
| Melting Point | Approx. 605°C – 650°C | ||||
| Thermal Conductivity | ~138 W/m·K |
Key takeaway: H32 and H34 are the most widely used tempers for general fabrication because they balance strength with enough ductility to bend and form without cracking, which is why they make up the bulk of stock at most Aluminium Sheet 5052 Dealer in Delhi counters, including HHhub.
Why Aluminium 5052 Is So Popular in Delhi’s Industrial Sector
Delhi NCR hosts a dense cluster of sheet metal fabricators, panel manufacturers, transport body builders, and electrical enclosure units all of whom rely on materials that combine strength, corrosion resistance, and formability. A few reasons 5052 dominates demand in this belt:
- Marine and outdoor durability -in tankers, water tanks, and outdoor cabinets exposed to Delhi’s extreme summer heat and monsoon humidity.
- Excellent weldability – compatible with TIG/MIG welding, useful for fuel tank fabrication and ducting.
- Good fatigue resistance – ideal for parts subject to continuous vibration such as truck bodies and machine panels.
- Lightweight advantage – reduces transport costs and structural load in fabricated assemblies.
- Cost efficiency versus stainless steel – offers comparable corrosion resistance at a lower material and fabrication cost for many applications.
Available Sizes, Thickness & Tempers
A reliable Aluminium 5052 Sheet Manufacturer should be able to supply a full spread of dimensions rather than a limited stock range. HHhub maintains ready inventory across the following specifications, with custom cutting available on request.
| Specification | Range Available at HHhub |
| Thickness | 0.5 mm – 50 mm (sheet & plate) |
| Standard Sheet Sizes | 4×8 ft, 5×10 ft, 1250×2500 mm, 1000×2000 mm |
| Custom Cut-to-Size | Available as per drawing/requirement |

| Surface Finish | Mill finish, brushed, polished, anodised |
| Form | Hot rolled & cold rolled sheets/coils |
| Standards Followed | ASTM B209, ASME SB209, EN 573, EN 485 |
Aluminium 5052 vs Other Common Grades
Buyers frequently confuse 5052 with other structural aluminium grades. Here’s a side-by-side comparison to help you choose the right alloy for your application.
| Grade | Key Strength | Corrosion Resistance | Weldability | Typical Use |
| 5052 | Moderate-high | Excellent (marine grade) | Excellent | Fuel tanks, marine parts, enclosures |
| 6061 | High (heat-treatable) | Good | Good | Structural frames, machined parts |
| 1100 | Low | Excellent | Excellent | Decorative panels, reflectors |
| 3003 | Low-moderate | Good | Excellent | Roofing, chemical equipment, HVAC |
| 6082 | High (heat-treatable) | Good | Good | Load-bearing structures, trailers |
If your application involves water/chemical exposure combined with a need for cold-forming (bending, deep drawing), 5052 remains the most balanced and economical choice which is why it stays the top-selling grade among HHhub’s clients.
Industry Applications of Aluminium 5052 Sheet
- Marine & Shipbuilding – hulls, deck fittings, and structural panels exposed to saltwater

| Mill Test Certificate (MTC) | Batch-specific proof of chemical and mechanical compliance |
A supplier unwilling to share these documents should be treated with caution, regardless of how competitive their offer sounds.
Common Buying Mistakes to Avoid
- Choosing the lowest quote without checking temper – a lower price often means a softer, less durable temper (like O instead of H32/H34).
- Ignoring mill test certificates – without an MTC, there is no way to confirm the alloy composition matches genuine 5052.
- Overlooking surface finish requirements – mill finish sheets are unsuitable for visible or anodised applications.
- Not confirming thickness tolerance – even a small deviation can affect fabrication accuracy in precision applications.
- Assuming all aluminium sheet listings are 5052 – many traders list generic “aluminium sheet” without specifying alloy grade; always confirm in writing.
