What Is 5383 Aluminum Equivalent
5383 aluminum sheet demonstrates exceptional corrosion resistance, particularly in harsh conditions such as marine environments. Its high magnesium (Mg) content, the primary alloying element, ranges from 4.0% to 5.2%. The resulting alloy structure with aluminum effectively resists corrosion from seawater, the marine atmosphere, and industrial chemicals.
5383 aluminum sheet's long-term corrosion resistance is significantly improved compared to 5083 H116 and H321. This makes it an ideal material for marine engineering applications such as shipbuilding, offshore platform construction, and desalination equipment.
5383 aluminum plate offers excellent mechanical properties, having approximately 10% greater strength than 5083 aluminum plate. By optimizing the alloy composition and processing technology, 5383 aluminum plate achieves improved yield strength while maintaining a certain level of ductility. In the common H116 and H321 tempers, its yield strength reaches a high level, providing reliable load-bearing capacity for structures.
This excellent balance of strength and ductility enables 5383 aluminum plate to withstand high stresses while avoiding structural failure due to brittle fracture. It is suitable for the manufacture of structural components requiring high strength and toughness, such as critical components such as ship hulls and keels.
5383 aluminum plate exhibits excellent weldability and is suitable for all standard welding methods, particularly gas metal arc welding (GMAW, also known as MIG welding) and gas tungsten arc welding (GTAW, also known as TIG welding). The filler alloy 5356 is the most commonly used choice for welding.
5383 aluminum plate has moderate machinability, which is related to the material's hardness state. In a harder state, machinability is excellent; in a softer state, machinability is moderate. This moderate machinability makes 5383 aluminum plate adaptable to a variety of processing methods, enabling it to demonstrate its advantages in various manufacturing scenarios.
Comparison of alternative options
5083 aluminum sheet
5083 aluminum plate is a 5383 aluminum equivalent. Its magnesium content is slightly lower, at 4.0% to 4.9%, compared to 5383 aluminum plate. Its tensile strength generally ranges from 270 to 350 MPa. While 5083 aluminum plate has slightly lower strength than 5383 aluminum plate, it also offers excellent corrosion resistance and is widely used in marine engineering. However, 5383 aluminum plate offers improvements in strength and weldability.
5383 aluminum sheet offers advantages for key structural components requiring high strength. Where strength requirements are less stringent and cost control is more stringent, 5083 aluminum sheet is a good choice. Welcome to inquire 5083 and 5383 aluminum price from us directly.
5052 aluminum sheet
5052 aluminum sheet is also a viable alternative. Its magnesium content ranges from 2.2% to 2.8%, making it lower than 5383 and 5083 aluminum sheets. This lower magnesium content results in a lower strength, typically between 230 and 280 MPa.
The advantages of 5052 aluminum sheet lie in its relatively low cost and good formability. It is widely used in applications where strength requirements are low but material cost and forming processes are important, such as automotive fuel tanks and ordinary building curtain walls. However, in areas such as marine engineering, where corrosion resistance and strength are more demanding, 5383 aluminum sheet is more suitable.
6061 Aluminum sheet
6061 aluminum sheet belongs to the Al-Mg-Si alloy family. Besides magnesium, its primary alloying elements are silicon (Si). After heat treatment (such as the T6 temper), 6061 aluminum sheet achieves a tensile strength of 310-370 MPa, representing high strength. However, its seawater corrosion resistance is limited, making it susceptible to pitting and other corrosion phenomena in marine environments.
In terms of weldability, 6061 aluminum sheet is also slightly inferior to 5383 aluminum sheet, and is prone to thermal cracking during welding. Therefore, 6061 aluminum sheet is unlikely to replace 5383 aluminum sheet in marine engineering and other applications requiring high weldability. However, 6061 aluminum sheet has advantages in applications such as mechanical structures and aerospace, where strength requirements are high and the corrosion environment is less severe.
