Aluminum Smooth Sheets — EN AW-5754 & EN AW-1050A
Aluminum smooth sheets are flat-rolled aluminum sheet metal products with a mill-finish surface, used across construction, transport, marine, signage and electrical industries. ULAMEX supplies aluminum sheets in two complementary alloys: EN AW-5754 H111/H22 — a marine-grade aluminum-magnesium alloy with excellent corrosion resistance and structural strength — and EN AW-1050A H24 — a 99.5% commercially pure aluminum with superior formability and electrical conductivity. Both alloys are available from stock in standard European formats with wholesale pricing and delivery across the EU.
Material Properties & Technical Specifications
EN AW-5754 H111/H22 (AlMg3, material no. 3.3535):
- Tensile strength (Rm): 190–290 MPa (H111: 190–240 MPa; H22: 245–290 MPa)
- Yield strength (Rp0.2): 80–180 MPa (H111: ≥80 MPa; H22: ≥130 MPa)
- Elongation (A50): ≥10% (H111: ≥14%; H22: ≥10%)
- Brinell hardness (HB): 55–75
- Density: 2.70 g/cm³
EN AW-5754 is a non-heat-treatable wrought alloy from the AlMg3 group, strengthened exclusively through strain hardening (cold working). The H111 temper represents a slightly strain-hardened condition — offering excellent formability while maintaining good structural integrity. The H22 temper is strain hardened and then partially annealed, delivering significantly higher tensile and yield strength for load-bearing applications. This alloy is classified as seawater-resistant and provides outstanding resistance to industrial atmospheres, alkaline solutions and salt spray environments.
EN AW-1050A H24 (Al 99.5, material no. 3.0255):
- Tensile strength (Rm): 105–145 MPa
- Yield strength (Rp0.2): ≥85 MPa
- Elongation (A50): ≥3%
- Brinell hardness (HB): 33–44
- Electrical conductivity: ≥59% IACS
- Thermal conductivity: 230 W/(m·K)
- Density: 2.71 g/cm³
EN AW-1050A is a 99.5% pure aluminum with the highest formability and deep-drawing capability in the aluminum sheet range. The H24 temper (strain hardened and partially annealed) provides a balanced combination of moderate strength and excellent ductility. Its high electrical and thermal conductivity makes it the preferred choice for bus bars, conductor plates, heat exchangers and reflectors. The material is food-safe (non-reactive) and suitable for chemical storage applications.

Applications by Industry
Marine & Shipbuilding (5754): Hull plating, deck panels, superstructure cladding, bulkheads, fuel and water tanks. EN AW-5754 is the standard marine-grade aluminum sheet for seawater-exposed structural components.
Transport & Vehicle (5754): Truck body panels, trailer side walls, floor plates, container construction, rail vehicle body shells. The combination of corrosion resistance, weldability and moderate strength makes 5754 the aluminium of choice for commercial vehicle manufacturers.
Construction & Architecture (5754 / 1050): Facade cladding panels, roofing sheets, HVAC ductwork, rain gutters, flashing. Aluminum sheet offers a maintenance-free, lightweight alternative to galvanized steel sheet with a fraction of the weight and no risk of rust.
Signage & Decoration (1050): Sign blanks, display panels, decorative trim, embossed lettering, name plates. The excellent surface quality and anodizing response of 1050A make it ideal for visible architectural and commercial applications.
Electrical & Electronics (1050): Bus bars, conductor plates, enclosures, transformer windings, heat sinks, reflectors. The ≥59% IACS conductivity of EN AW-1050A delivers near-copper electrical performance at one-third the weight.
Packaging & Food (1050): Food processing equipment liners, tank linings, chemical vessel cladding. The food-grade, non-reactive properties of pure aluminum make it suitable for direct food contact applications.
Chemical Industry (5754): Chemical-resistant vessel cladding, flue gas desulphurisation equipment, sewage plant components. EN AW-5754 resists attack from a wide range of chemicals and maintains its integrity in permanently wet conditions.
Material Comparison
EN AW-5754 vs EN AW-5083: 5083 offers approximately 15–20% higher tensile strength (275–350 MPa) but at significantly higher material cost. For the majority of marine and structural applications, 5754 provides the optimal balance of strength, corrosion resistance and cost-effectiveness.
EN AW-1050A vs EN AW-3003: 3003 offers approximately 40% higher tensile strength (130–180 MPa) due to its manganese content, but at the expense of reduced electrical conductivity and formability. Choose 1050A when maximum formability, deep drawing or electrical conductivity is the primary requirement.
Aluminum sheet vs galvanized steel sheet: At approximately 2.70 g/cm³ vs 7.85 g/cm³, aluminum sheet is 65% lighter than steel. Aluminum provides inherent corrosion resistance without coatings, lower lifecycle cost and full recyclability — making it the superior choice for facade, transport and marine applications where weight and durability matter.
Aluminum sheet vs stainless steel sheet: Stainless steel offers higher strength and temperature resistance but at 3× the weight and 2–4× the cost per square meter. Aluminum is preferred when weight savings, thermal/electrical conductivity or cost efficiency are decisive factors.
Processing & Fabrication Guide
Bending: EN AW-1050A offers excellent cold bending performance with minimum bend radii of 0.5× thickness. EN AW-5754 H111 bends well at 1× thickness; H22 requires 1.5–2× thickness minimum bend radius.
Welding: EN AW-5754 is readily weldable by TIG and MIG processes using AlMg5 (ER5356) filler wire. EN AW-1050A is also easily weldable using AlSi5 (ER4043) filler. Preheat is generally not required.
Cutting: Both alloys can be processed by guillotine shear, laser cutting, waterjet cutting, plasma cutting and CNC routing.
Deep drawing: EN AW-1050A offers excellent deep-drawing performance. EN AW-5754 H111 is suitable for moderate forming operations.
Surface treatment: Anodizing (natural, black, coloured), brushing, polishing, powder coating and protective film application are all available.

Frequently Asked Questions
What is the difference between aluminum 5754 and 1050?
EN AW-5754 is an aluminum-magnesium alloy (AlMg3) with tensile strength up to 290 MPa, excellent corrosion resistance and good weldability — designed for structural and marine applications. EN AW-1050A is 99.5% pure aluminum with lower strength (105–145 MPa) but superior formability, deep-drawing capability and electrical conductivity (≥59% IACS). Choose 5754 for strength and corrosion resistance; choose 1050A for forming, electrical applications and food-grade use.
How much does a 2 mm aluminum sheet weigh per square meter?
A 2 mm aluminum sheet weighs 5.40 kg per square meter. The formula is: thickness (mm) × 2.70 (density of aluminum in g/cm³) = weight in kg/m².
Can aluminum sheet be bent without cracking?
Yes. EN AW-1050A H24 bends easily with minimum bend radius of 0.5× material thickness. EN AW-5754 H111 bends well at 1× thickness. For H22 temper, use 1.5–2× thickness as minimum bend radius to avoid cracking.
What is the best aluminum sheet for outdoor and marine use?
EN AW-5754 is classified as seawater-resistant and is the standard choice for marine hull plating, outdoor facade cladding and applications exposed to salt spray, rain and industrial atmospheres.
What aluminum sheet sizes are available?
ULAMEX stocks aluminum sheets in three standard formats: 1000×2000 mm, 1250×2500 mm and 1500×3000 mm. Aluminum sheet cut to size is available on request for custom dimensions.
What is the difference between smooth sheet and checker plate?
Smooth sheet (flat sheet) has a uniform mill-finish surface on both sides and is used for structural, decorative and fabrication applications. Checker plate (tread plate, Riffelblech) has a raised pattern on one side providing anti-slip grip — used for stair treads, vehicle floors and industrial walkways.
