Detail
Weldability
EN AW 5083 offers excellent weldability. The material shows high crack resistance during and after welding due to its magnesium content. MIG and TIG welding processes are commonly used. No additional heat treatment is generally required after welding, since the alloy is not substantially weakened by the welding process.
Detail
Machinability
EN AW 5083 has moderate machinability. With appropriate tooling, machining parameters and cutting fluids, acceptable results can be achieved. To avoid excessive tool wear, moderate to low cutting speeds are recommended. Moderate depth of cut is advised to reduce tool load and promote effective chip formation. Emulsions or synthetic cutting fluids can reduce friction and cool the tools.
Detail
Forgeability
The alloy has good forgeability. Optimal forging temperatures lie between 350°C and 450°C. When heated, the material exhibits good deformability and is not prone to cracking.
Detail
Magnetism
Aluminum is non‑magnetic. Even with alloying elements such as magnesium, the alloy remains non‑magnetic.
Detail
Corrosion resistance
This aluminum alloy shows excellent corrosion resistance. It performs well in industrial environments with chemical exposure and in marine environments with saltwater. It is resistant to stress‑corrosion cracking as well as to pitting and crevice corrosion, making it suitable for applications exposed to both mechanical stress and corrosive environments.
