Material Data Sheet
EOS NickelAlloy K500
Versatile alloy for highly corrosive environments
EOS NickelAlloy K500 is a versatile alloy designed for especially highly corrosive environments. The material offers a unique combination of mechanical properties, corrosion resistance, and thermal conductivity that make it ideal for a variety of demanding applications.
- Good mechanical strength also in elevated temperatures
- Excellent corrosion resistance
- Moderate conductivity (approximately two times the conductivity of commonly used nickel superalloys)
- Aerospace
- Marine
- Industrial applications
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 NickelAlloy K500 is a precipitation strengthened alloy. The strength of the material can be tailored using heat treatment. An ageing heat treatment directly after printing is recommended for applications where strength is the primary concern.
Direct aging
Hold at 595 °C measured from the part for 2 h in argon atmosphere, followed by slow air cooling.
