Which consequence increased when alloying copper with arsenic?

💡 Explanation

Higher arsenic content embrittles copper-arsenic alloys through grain boundary segregation, with work hardening providing greater yield strength because work hardening hinders dislocation motion. Therefore tensile strength would increase, rather than reduce ductility, if arsenic ratio is well controlled during manufacturing.
