Two different heat treatments are recommended for EOS CopperAlloy CuCrZr - one conductivity optimized and one tensile properties optimized.
Conductivity optimized HT*:
Ageing: 3 h at 550 °C under inert gas flow/atmosphere.
Slow cooling in inert gas until temperature is below 100 °C
Tensile optimized HT:
Ageing: 1h hold in 490 °C under inert gas flow/atmosphere.
Slow cooling in inert gas until temperature is under 100 °C
*Heat treatment developed in cooperation with University of Padua and Istituto Nazionale di Fisica Nucleare
