Material Data Sheet
EOS Aluminium Al5X1
High Strength & High Elongation Aluminium for AM
EOS Aluminium Al5X1 is a heat-treatable aluminium alloy designed for AM to offer a compelling combination of high strength and high elongation. Al5X1 exhibits excellent mechanical properties with a strength above 400 MPa and an elongation exceeding 13% after heat treatment. The recommended single-step heat treatment does not require a water quench and enables robust part production.
- Excellent combination of strength & elongation
- Good corrosion resistance
- Parts can be anodized
- Aerospace
- Automotive
- Marine
- Lightweight designs
The EOS Quality Triangle
EOS incorporates these TRLs into the following two categories:
- Premium products (TRL 7-9): offer highly validated data, proven capability and reproducible part properties.
- Core products (TRL 3 and 5): enable early customer access to newest technology still under development and are therefore less mature with less data.
All of the data stated in this material data sheet is produced according to EOS Quality Management System and international standards

HEAT TREATMENT
Heat treatment procedure
Direct ageing heat treatment
6 hours at 400 °C. Immediate gas quenching (air cooling with maximal air flow).
Preferred inert atmosphere during furnace treatment.
