In the vast realm of metallic materials, 5083 aluminum plate stands out prominently with its exceptional properties, becoming the top choice for numerous industries. Whether it's used in shipbuilding to withstand the corrosion of seawater or in pressure vessels to endure high - pressure conditions, 5083 aluminum plate demonstrates unparalleled advantages. If you're in search of a metal material that combines high strength, excellent corrosion resistance, and good weldability, then 5083 aluminum plate is undoubtedly an option worthy of in - depth exploration. Next, let's unveil the mystery of 5083 aluminum plate and discover its unique charm and key characteristics in various industrial applications.

5083 Aluminum Alloy Description

5083 aluminum alloy, a representative of the 5xxx series (aluminum - magnesium alloys), is a high - magnesium alloy. It boasts excellent corrosion resistance, making it ideal for marine and harsh - environment applications. With superior weldability and good formability in the annealed state, it’s widely used in shipbuilding, pressure vessels, and structural parts. Containing significant magnesium, it’s processed via hot rolling, ensuring stable internal structure. Common tempers like O, H111, H32, and H116 (for Mg - content ≥ 4% 5xxx alloys, enhancing exfoliation corrosion resistance) suit diverse needs, proving vital in industries demanding strength and durability.

5083 aluminum Common Temper

Temper	Description
H116	Applicable to 5xxx series alloys with Mg content ≥ 4%, featuring stable resistance to exfoliation corrosion
H321	For 5xxx series alloys with Mg content ≥ 4%; work hardening degree in hot and cold working is slightly less than that of H32
O	Annealed to the softest temper
H111	After annealing, additional cold deformation processing in aluminum fabrication is required
H112	Indicates products formed by hot working (i.e., the state after hot rolling without any heat treatment)
H32	Grain hardening, stabilized to 1/4 hard

5083 aluminum Features

1. Mechanical Properties

It has good strength. Among non - heat - treatable alloys, its performance is outstanding. The tensile strength is ≥ 270 MPa, and the proof stress is ≥ 110 MPa. It also has decent anti - fatigue performance, being able to withstand relatively large external forces and impacts. It has a good balance between strength and plasticity, making it suitable for use as structural components.

2. Corrosion Resistance

It has excellent corrosion resistance, especially against corrosion in seawater and chlorine - containing environments. Magnesium in the alloy forms a dense oxide layer that blocks Cl - ions. It remains stable in marine and harsh industrial environments, not prone to rusting and corrosion. In a 3.5% NaCl solution, the corrosion rate of its natural oxide film is low, and it has a long corrosion - resistant time in salt spray tests, making it suitable for maritime and other occasions requiring corrosion resistance.

3. Processing Properties

It has good formability. In the annealed state (O state), the deep - drawing elongation rate exceeds 30%, and it can be made into products of various shapes and sizes. It has excellent weldability, and various welding methods such as arc welding can be applied. The weld strength is high, and the efficiency of the welded joint can reach 95%. The decrease in strength and corrosion resistance after welding is small. In addition, it is easy to be machined, with low cutting force and long tool life.

4. Properties in Special Environments

It has good low - temperature toughness and can adapt to extreme environments down to - 269 °C. Instead, its strength increases at low temperatures, and it has good fracture toughness, so it can be used in polar ships, LNG storage tanks, etc. However, the long - term service temperature should be ≤ 65 °C to avoid stress corrosion cracking.

5083 aluminum application

Thin plates:

Used for automotive parts (e.g., body components), new energy vehicle battery side plates (lightweight, corrosion - resistant for battery protection), and building facades (durable, decorative for curtain walls).

Thick plates:

Applied in mold manufacturing (good formability for complex shapes), storage tanks (resists chemical/liquid corrosion), shipbuilding (deck structures) (withstands marine environments), and air separation equipment (handles low - temperature, high - pressure conditions stably).
