I dont know where heating copper makes it brittle, I always heat copper tubing to make it softer if it has been work hardened. I would say more likely the copper under pressure from a crimp would be work hardened and maybe more brittle. And while we talk about household stuff being crimped I dont see that very often with the hard single strand stuff used in the USA, now stranded conductors , that is another story where thay should be crimped or held in a captive clamp connecter.
