Advantages and Disadvantages of Aluminum 5083H116 and 5083H321

Marine aluminum plate is used in building ships, cruises and yachts to resist corrosion from seawater and industrial chemicals.aluminum 5083h116; aluminum 5083h321 The material retains exceptional strength after welding and has good formability, thermal conductivity and low density. Its excellent corrosion resistance also makes it suitable for tanker load containers. Moreover, it is light and can improve ship speed and extend its service life.

The 5083 alloy is a strong magnesium-manganese-chromium-aluminum aluminum plate.aluminum 5083h116; aluminum 5083h321 It can be hardened by cold work but is not heat treatable to higher strengths, as most 5000 series alloys. This limits the use of the alloy for structural applications involving sustained exposure to high temperatures, as it is susceptible to stress corrosion cracking due to its higher magnesium content. However, it has good ductility for its strength level, better than most 5000-series alloys. Austral Wright Metals can supply this alloy as plate, sheet and strip.

Compared to 5052, the alloy has higher thermal conductivity and strength.aluminum 5083h116; aluminum 5083h321 It can be formed and welded easily. It is used in vehicle body parts such as automobile fuel tanks, aircraft fuel tanks and bus skins, as well as other heavy equipment like dump bodies. It is also used as a structural material in the construction of ships, pressure vessels and storage tanks.

In addition to its good corrosion resistance, the 5083 alloy has excellent mechanical properties.aluminum 5083h116; aluminum 5083h321 It can be readily formed, welded and machined. It is also highly resistant to attack by saline and industrial chemicals and has good fatigue resistance.

Because of these desirable characteristics, 5083 is the preferred choice for marine aluminum plate.aluminum 5083h116; aluminum 5083h321 However, its magnesium content, which can reach 4.0%, makes it susceptible to stress corrosion cracking at elevated temperatures. In order to reduce the risk of this type of failure, it is important to understand the effects of temperature on the alloy’s metallurgical and mechanical properties.

A physics-based model has been developed to predict the behavior of the AA-5083 alloy at various loading temperatures and strain rates.aluminum 5083h116; aluminum 5083h321 The model incorporates the interaction between dislocations and obstacles and can be calibrated using experimental data. This method provides predictive capability that can be useful to design engineers.

To achieve the best mechanical properties, 5083 aluminum plates must be processed in accordance with specific standards.aluminum 5083h116; aluminum 5083h321 These include the physical properties of the material, such as tensile strength and yield strength, and its elongation and hardness. The material should also be free of defects and impurities, such as b phase and precipitates. This is achieved by performing aging softening, stabilizing annealing and strain hardening on the material to obtain the desired properties. The h321 temper is the most commonly used temper of the alloy for marine applications. The h321 temper has an tensile strength of over 305 MPa, conditional yield strength of over 215 MPa and elongation of over 10%. Moreover, the h321 temper has excellent torsional stiffness. This is especially important for the structure of large vessels. The h321 temper also has good resistance to spalling corrosion.
