Aluminum, with its high strength to weight ratio is a terrific material for many applications. However, even the highest modulus aluminums at their highest tempers (6061-T6) will not be able to withstand years of a higher modulus material (stainless wire rope) abrading it. So, if a stainless steel wire rope halyard is being drawn over an aluminum rod then the rod will wear and eventually be cut through.
