Aluminium Coil 5754 O H111 is a non-heat-treatable aluminum-magnesium alloy widely valued for its excellent corrosion resistance, good weldability, attractive surface quality, and dependable formability. It belongs to the 5xxx series and is frequently selected for applications where strength, light weight, and durability must be balanced. In coil form, 5754 is especially useful for continuous processing, sheet fabrication, stamping, panel production, and transportation components.
For customers looking for a practical material for marine, automotive, tank, and industrial sheet applications, 5754 O and H111 tempers offer a versatile solution. The O temper provides maximum softness and high formability, while H111 offers slightly increased strength with retained workability.
5754 aluminum coil contains magnesium as its main alloying element, giving it a strong combination of moderate strength and outstanding resistance to seawater and industrial environments. Compared with many general-purpose aluminum grades, it performs particularly well in corrosive service conditions and is often preferred for structures exposed to humidity, chemicals, or salt-laden air.
The two common tempers in this product designation serve different fabrication goals:
| Temper | Description | Main Benefit |
|---|---|---|
| O | Fully annealed | Highest ductility and formability |
| H111 | Slightly strain-hardened from shaping processes | Better strength while maintaining good formability |
This makes Aluminium Coil 5754 O H111 suitable for fabricators who need a reliable alloy for bending, forming, welding, and surface finishing.
Features
| Feature | Performance Benefit |
|---|---|
| Excellent corrosion resistance | Performs well in marine, coastal, and industrial atmospheres |
| Good weldability | Compatible with common welding methods for fabrication |
| Good formability | Suitable for bending, drawing, pressing, and shaping |
| Medium strength | Stronger than 1xxx and many 3xxx alloys while still workable |
| Low density | Helps reduce overall product weight |
| Attractive surface finish | Suitable for visible panels and decorative use |
| Good anodizing response | Can be used for enhanced surface protection and appearance |
| Non-heat-treatable stability | Strength is achieved through composition and work hardening |
Applications of Aluminium Coil 5754 O H111
Because of its versatility, this alloy is used across many sectors where both mechanical performance and corrosion resistance matter.
| Industry | Typical Uses |
|---|---|
| Automotive | Inner panels, body parts, floor panels, heat shields, structural sheet |
| Marine | Boat panels, hull-related sheet parts, deck components |
| Tank and pressure equipment | Fuel tanks, storage tanks, tank truck bodies |
| Construction | Roofing, cladding, wall panels, façade elements |
| Industrial manufacturing | Cabinets, enclosures, fabricated sheet parts, machinery covers |
| Transportation | Trailer panels, rail interiors, cargo body panels |
| Food and chemical sectors | Containers, processing equipment, protective covers |
In automotive and transportation markets, 5754 coil is often selected for its ability to reduce weight without sacrificing service reliability. In marine and tank applications, its corrosion resistance is a major advantage.
Chemical Composition
The exact composition may vary slightly according to the applicable standard, but typical values for 5754 aluminum alloy are shown below.
| Element | Typical Content (%) |
|---|---|
| Magnesium (Mg) | 2.6 – 3.6 |
| Manganese (Mn) | 0.50 max |
| Iron (Fe) | 0.40 max |
| Silicon (Si) | 0.40 max |
| Chromium (Cr) | 0.30 max |
| Zinc (Zn) | 0.20 max |
| Titanium (Ti) | 0.15 max |
| Copper (Cu) | 0.10 max |
| Aluminum (Al) | Balance |
The magnesium content is the reason for the alloy's strong corrosion resistance and good strength level among non-heat-treatable aluminum materials.
Mechanical Properties
Mechanical values depend on thickness, production route, and applicable standard. The following table shows commonly referenced typical ranges for coil products.
| Property | 5754 O | 5754 H111 |
|---|---|---|
| Tensile Strength (MPa) | 190 – 240 | 200 – 250 |
| Yield Strength (MPa) | 80 min | 90 min |
| Elongation (%) | 12 – 20 | 10 – 18 |
| Hardness | Lower | Slightly higher |
| Formability | Excellent | Very good |
The O temper is preferred where deep forming or complex shaping is required. The H111 temper is often chosen where a mild increase in strength is beneficial without losing too much flexibility in fabrication.
