- Good thermal and electrical conductivity
- Properties can be modified with heat treatments
- General engineering components and parts subject to high loads
- Lightweight designs
- Aerospace and automotive components
- Substitution of cast AlSi10Mg parts
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
EOS T6 Heat Treatment
EOS has developed an AM optimized heat treatment procedure that is 40% shorter than conventional T6 heat treatment procedures.
Solution annealing 30 min @ 530 °C, water quench. Artificial aging 6 h @ 165 °C, cooling in air. Parts to preheated oven. Maximum overheating 5 °C. Delay between SA and quenching maximum 30 s. Oven type & configuration may have impact on the mechanical properties. For complex and massive parts uniform heating and cooling needs to be arranged.
EOS T6 treatment is recommended to obtain controlled mechanical properties and lower variation in mechanical values (for example in long build jobs if heat transfer from parts is limited by low amount of support and after stress relief heat treatment). An increase in porosity due to heat treatment is possible. A more detailed description of heat treatment is available upon request.
Solution Annealing
30 minutes in 530 °C followed by immediate quenching to water.

30 minutes in 530 °C followed by immediate quenching to water.
Aging:
Artificial aging of 6 hours in 165 °C followed by cooling in air.
In case higher build platform temperature is used it is strongly advised to perform EOS T6 heat treatment in order to obtain mechanical properties similar to those stated in the MDS.

EOS T6 Heat Treatment
EOS has developed an AM optimized heat treatment procedure that is 40 % shorter than conventional T6 heat treatment procedures.
Solution annealing 30 min @ 530 °C, water quench. Artificial aging 6 h @ 165 °C, cooling in air. Parts to preheated oven. Maximum overheating 5 °C. Delay between SA and quenching maximum 30 s. Oven type & configuration may have impact on the mechanical properties. For complex and massive parts uniform heating and cooling needs to be arranged.
EOS T6 treatment is recommended to obtain controlled mechanical properties and lower variation in mechanical values (for example in long build jobs if heat transfer from parts is limited by low amount of support and after stress relief heat treatment).
An increase in porosity due to heat treatment is possible. A more detailed description of heat treatment is available upon request.
