(OP)
Dear Friends,
For AlMgSi0,7 F27 (6005) type alloy, I wonder about the quenching type of material at the press exit? Is water quenching necessary to catch up the mechanical strength value( it is about 270 MPa(tensile))
Thank you!!

RE: AlMgSi0,7 F27
ASM Metals Handbook Vol. 4 p.1853 indicates that it might be directly quenched. I would try air-blasting at the exit of the extruder since it is easy to implement. Hardness testing should indicate whether you achieved a proper Mg2Si precipitation or not (around 95 HB).
Take care of the thick sections since the precipitation might be coarse and its distribution poor if enough cooling speeds is not applied.
I hope my note is useful!
