Aluminum alloys commonly used for reefer containers belong to the 5xxx and 6xxx series. These alloys offer a balance of strength, corrosion resistance, and weldability, making them suitable for container construction. Among the various aluminum alloys available, the following are often used for reefer containers:

  1. Alloy 5083: This alloy is known for its excellent corrosion resistance and moderate strength. It is often used for the outer shell of reefer containers due to its ability to withstand harsh marine environments. Alloy 5083 also has good weldability, making it suitable for fabricating container components.
  2. Alloy 6061: Alloy 6061 is a versatile alloy with good strength and excellent machinability. It’s often used for internal components and structural elements of reefer containers. It has good corrosion resistance and can be heat-treated for enhanced strength.
  3. Alloy 6063: Similar to 6061, alloy 6063 is used in reefer container construction due to its favorable combination of strength, corrosion resistance, and formability. It’s often chosen for components that require intricate shapes or profiles.

The specific alloy chosen depends on the design requirements and the intended use of the reefer container. Factors such as the cargo being transported, the container’s size, weight considerations, and environmental conditions play a role in selecting the appropriate alloy.

Keep in mind that the manufacturing process, including welding, forming, and joining, also influences alloy selection. Weldability and formability are critical considerations to ensure that the chosen alloy can be effectively fabricated into the desired container design.

Ultimately, the choice of aluminum alloy for reefer containers is a balance between strength, corrosion resistance, weldability, and other performance characteristics required to meet the demands of transporting temperature-sensitive goods in various environments.
