5383 H116 Aluminum

5383-H116 aluminum offers good corrosion resistance through specific heat treatment and cold working, making it suitable for light-load marine applications, especially for long-term use in seawater environments.

5383-H116 aluminum is the H116 temper of the 5383 aluminum alloy, a state achieved through specific heat treatment and processing to enhance the material's properties. The primary purpose of the H116 temper is to ensure better corrosion resistance of the aluminum alloy in marine environments while maintaining certain mechanical strength.

5383-H116 aluminum is an alloy primarily designed for marine applications. In the H116 temper, it has enhanced corrosion resistance, particularly to seawater corrosion, through appropriate heat treatment and cold processing. Although its strength and fatigue strength are lower, it performs excellently in resisting corrosion and handling light loads, making it suitable for use in ships and marine structures.

5383-H116 Aluminum Properties

Temper and Hardness

The H116 temper is the result of cold working the 5383 aluminum alloy after heat treatment, aimed at achieving specific mechanical properties through moderate stretching and processing of the material.

The 5383 aluminum alloy in the H116 temper has lower hardness and strength but exhibits superior corrosion resistance compared to other aluminum alloys, especially in resisting seawater corrosion.

Intergranular Corrosion and Exfoliation Corrosion

In the H116 temper, the intergranular corrosion and exfoliation corrosion characteristics of the aluminum alloy are treated to effectively prevent the spread of corrosion when exposed to marine environments for extended periods.

Specific treatments control corrosion at the grain boundaries through minor corrosion action, which helps extend the material's lifespan in extreme environments.

Strength and Toughness

5383-H116 aluminum has moderate tensile strength and yield strength, sufficient for general marine applications, such as hull structures and some external parts of ships.

The material has moderate toughness, making it suitable for applications where extreme strength is not required.

Corrosion Resistance

The greatest advantage of 5383-H116 aluminum is its excellent corrosion resistance, particularly its ability to resist saltwater corrosion in marine environments. This makes it widely used in the construction of ships, offshore platforms, and other marine structures.

The corrosion resistance of this alloy is stronger than that of other aluminum alloys, making it suitable for long-term exposure to water and salt-rich environments.

5383 H116 Aluminum Applications

5383 H116 aluminum alloy is widely used in marine and shipbuilding fields due to its excellent seawater corrosion resistance and light load-bearing capacity, especially in structures that are exposed to marine environments for extended periods but do not bear extreme strength loads.

Application Field Description
Shipbuilding 5383-H116 aluminum alloy is widely used in external parts of ships, such as hulls, hull structures, and decks. These parts are exposed to a saltwater environment and must have corrosion resistance. The H116 aluminum alloy provides sufficient corrosion resistance, making it suitable for components with relatively low strength requirements, ensuring the long-term use and structural integrity of the ship.
Marine Structures In marine structures, 5383-H116 aluminum alloy is primarily used in components exposed to seawater, such as buoys, offshore platform support parts, and floating structures. These structures need to resist corrosion in the marine environment and typically bear relatively light loads, so the strength and corrosion resistance of the H116 aluminum alloy make it ideal for these applications.
Seawater Pipelines Due to its excellent corrosion resistance, 5383-H116 aluminum alloy is also used in the manufacture of seawater pipelines, particularly those in seawater transport systems. These pipelines need to operate in marine environments for long periods, and the corrosion resistance of H116 aluminum alloy ensures the long-term stability and reliability of the pipelines.
Light-load Structures 5383-H116 aluminum alloy is suitable for light-load applications, such as smaller marine engineering structures, equipment supports, and frame structures. These structures typically require a certain amount of strength but do not need to withstand extreme pressure and weight loads. The strength and corrosion resistance of H116 aluminum alloy make it an ideal choice for these applications.
External Parts of Hulls As external components of the hull, 5383-H116 aluminum alloy is extensively used in areas such as hulls, shells, and decks. Since these parts are exposed to seawater for long periods, corrosion resistance is a key requirement, and the H116 aluminum alloy can effectively resist seawater corrosion while providing reliable performance without bearing excessive loads.

5383-H116 aluminum alloy, with its excellent corrosion resistance and moderate strength, is widely used in shipbuilding, marine structures, and light-load marine engineering. It is an ideal material choice, particularly for components exposed to seawater environments and not subjected to extreme strength loads, such as external hulls, decks, frame structures, and seawater pipelines.
