Product Description
This 5052 aluminum alloy sheet is the plate grade tank fabricators reach for when a steel tank is too heavy and a pure aluminium tank is too soft. The alloy carries 2.2 to 2.8 percent magnesium, which lifts yield strength to at least 160 MPa while keeping elongation above 12 percent, so a 4mm plate can be rolled into a cylinder, flanged and welded without cracking along the bend.
In H32 temper the sheet arrives strain-hardened and stabilised, meaning the mechanical properties stay put after forming instead of drifting during service. Density is roughly one third that of steel, so a 400 litre truck tank that weighs 120 kilograms in mild steel comes out close to 45 kilograms in 5052 — a saving that converts directly into payload.
The magnesium addition also builds a self-healing oxide film that shrugs off diesel, petrol, biodiesel blends, hydraulic oil and road salt, which is why aluminium tanks outlive painted steel ones in winter markets. Plates are supplied ultrasonically inspected and leak-tested on request, and edges are trimmed square so CNC plasma or waterjet cutting starts from a clean datum.
Density of 2.68 g/cm³ cuts tank shell weight by about 40 percent against mild steel and raises vehicle payload.
Stable H32 temper welds with ER5356 filler to full joint efficiency and keeps heat-affected zones from softening unpredictably.
Magnesium-bearing alloy resists diesel, petrol, biodiesel blends and hydraulic fluids without internal coating.
Self-forming oxide layer plus 500-hour salt spray performance protects chassis-mounted tanks in winter road conditions.
Thickness tolerance of ±0.1mm on 4mm plate keeps formed shells concentric and reduces weld gaps.
Ultrasonic inspection, hydrostatic leak test reports and mill certificates are issued with every tank order.

Road transport is the biggest market: aluminium diesel tanks for tractors, rigids and tipper trucks, hydraulic oil tanks for refuse bodies and cranes, and saddle tanks for long-haul fleets that need extra range. Trailer builders use the plate for fuel pods and tool-box combinations, while marine yards fabricate petrol tanks for RIBs and workboats from the same alloy because it tolerates permanent saltwater contact.
Stationary equipment accounts for another share, including generator base tanks, compressor receiver shells, fire-fighting water tanks and mobile refuelling trailers. Because the material is food-safe when correctly cleaned, it also appears in edible-oil transport tanks and in chemical tanks storing neutral solutions. Pressure vessel shops choose the grade for low-pressure air receivers where weight and corrosion resistance matter more than high yield strength.
Plates are interleaved with kraft paper, stacked on wooden pallets, banded with steel strip and wrapped for sea freight; a 20GP container holds about 22 metric tons. Each heat is tested for tensile strength, yield, elongation and chemical composition, and ultrasonic inspection can be added for tank shells where internal defects are critical.
Welding procedure qualification data for ER5356 filler is available on request so that fabricators can benchmark their own procedures. Cut edges are square and burr-free, protecting press-brake tooling and reducing weld preparation time on site.
