3003 H14 Aluminum Sheet Features
① 3003 aluminum alloy uses manganese (Mn) as the primary alloying element and cannot be strengthened by heat treatment.
② It offers excellent plasticity and good weldability, with corrosion resistance slightly better than 1050 alloy. It belongs to the medium-strength aluminum alloy category.
③ Two annealing methods are available:
Low-temperature annealing at 260–360°C
High-temperature annealing at 370–490°C

3003 H14 Aluminum Sheet Applications
3003 H14 aluminum sheet is mainly used where slightly higher strength than 1xxx series alloys is required, including:
Pressure tanks and storage tanks
Thermal insulation materials
Mechanical components
Automotive and aircraft fuel tanks
Air conditioners and refrigerators
Applications in humid environments
Compared with the 1xxx series, 3003 aluminum offers better performance and is one of the most widely used aluminum alloys.

Aluminum Tread Plate 3003 H14
Because 3003 aluminum is known as anti-rust aluminum and is significantly stronger than 1050 alloy, it is widely used for:
Aluminum tread plates
5-bar checkered plates
Diamond plates
Typical applications include refrigeration flooring, truck floors, stairs, and indoor/outdoor decorative flooring.

Aluminum Roofing Corrugated Sheet/Coil 3003
3003 aluminum alloy in H14 or H16 temper is also suitable for color-coated roofing sheets and coils, offering durability and corrosion resistance.
Packing and Loading
GNEE aluminum plates are packed in seaworthy packaging to protect against moisture and contamination.
Heat numbers are recorded on all bundles
Different heats are not mixed
Sizes are bundled separately
One side protected with 2–3 mil PVC film
Surface quality requirements: no chatter marks, pits, welds, or stains
Wooden skids suitable for flat-rack container loading
Aluminum 3003 vs 1050
3003 aluminum plate has higher hardness than 1050 aluminum sheet.
3003 hardness: 30–35 HB
1050 aluminum contains ≥99.5% aluminum and is therefore softer, with a hardness difference of about 10%.
Applications:
3003 aluminum: building facades, vehicle linings, bus panels, product enclosures
1050 aluminum: insulation pipes, ceilings, lighting stampings
Property Comparison
| Alloy | Tensile Strength | Yield Strength | Elongation (%) | Hardness | Fatigue Strength |
|---|---|---|---|---|---|
| 3003 | 150 | 145 | 13 | 40 | 62 |
| 1050 | 100 | 103 | 10 | 26 | 34 |
Aluminum 3105 vs 3003
3105 aluminum offers good rust resistance and electrical conductivity (up to 41%). It is commonly used for room partitions, color-coated substrates, lamp components, shutters, bottle caps, and closures.
3003 aluminum is a classic Al–Mn alloy with excellent formability, corrosion resistance, and weldability. It is widely used for power battery housings, cookware, food storage equipment, tanks, pressure vessels, and transportation pipelines.
Property Comparison
| Alloy | Tensile Strength | Yield Strength | Elongation (%) | Hardness | Fatigue Strength |
|---|---|---|---|---|---|
| 3003 | 150 | 145 | 13 | 40 | 62 |
| 3105 | 150 | 130 | 3 | 40 | 60 |
