Aluminum 5083h116 and Aluminum 5083h321

Aluminum 5083h116 and aluminum 5083h321 belong to marine aluminum plate, which is specially processed by heat treatment to have stable mechanical properties.aluminum 5083h116; aluminum 5083h321 It is widely used in shipbuilding and other industrial fields, such as automobiles and truck tanks.aluminum 5083h116; aluminum 5083h321 It is characterized by low density, high tensile strength and high elongation. The h321 variant is heat treated at lower temperature after work hardening, or directly heated during the processing, which results in higher tensile strength, elongation and hardness than 5083 h116.

The 5083 h321 aluminum plate has excellent welding performance, which makes it more suitable for shipbuilding applications.aluminum 5083h116; aluminum 5083h321 It can be easily welded with GMAW (MIG) and GTAW (TIG) processes using 5356 or 5556 filler alloys, which will result in good tensile and yield strengths of the weld area. This will also help to reduce the number of welds and improve the corrosion resistance of the welds.

In addition, it can be easily formed with cold forming and bending.aluminum 5083h116; aluminum 5083h321 This helps to improve the length-to-width ratio of ships and make them easier to maneuver. The low density of the alloy also contributes to less fuel consumption by reducing the weight of the ship. It can be easily formed to produce a variety of shapes, which will help save costs and resources for the shipbuilding industry.

Alloy 5083 is resistant to a wide range of industrial chemicals, including mild acid and salt water solutions.aluminum 5083h116; aluminum 5083h321 However, it is not recommended for use in aqueous solutions with a pH above 9. The corrosion resistance of this alloy depends on the formation of a dense protective oxide film. This film can be improved by anodizing, which will thicken the oxide layer and increase corrosion resistance.

This alloy is susceptible to exfoliation corrosion, but it passes the ASTM G66 Exfoliation Susceptibility Test.aluminum 5083h116; aluminum 5083h321 It is important to note that it reacts with oxidizing media more quickly than other aluminium alloys and may be susceptible to galvanic corrosion when in electrical contact with most other metals. Therefore, Austral Wright Metals recommends careful selection and regular inspection for galvanic corrosion risk.

Alloy 5083 has excellent resistance to general corrosion in aqueous environments, but it is not recommended for use in environments with a high level of humidity or chloride contamination.aluminum 5083h116; aluminum 5083h321 It is, however, resistant to reducing acids and can be used in cryogenic applications. Alloy 5083 can be cooled to temperatures below -195 degC without losing its strength or brittleness and is ideal for use in marine applications. It also retains exceptional strength after welding, which helps to reduce the number of welds. This is a crucial feature for shipbuilding. It can reduce the risk of accidents resulting from galvanic corrosion, which can cause injuries and financial loss. The alloy is also highly resistant to hydrogen embrittlement, making it a suitable material for keels and other structural components in marine environments. For this reason, it is a popular choice for shipbuilding. It can be easily welded and is highly durable, which helps to reduce maintenance costs and downtime.
