The aluminum is not loaded with copper, it is coated with copper in a process similar to 'Dip' Galvanizing with zinc on steel. The cable is a bundle of small flexible conductors thus it is flexible. Not a single rod of aluminum which would cause work hardening and fracture, a realistic failure mode. The copper makes weather corrosion of the aluminum unlikely. And when using for home wiring the copper coating improves the connection reliability.
