being heavier means that it has more material. More material is stronger thus meaning that it could be better than a supposed high end frame.

Heavier does not mean stronger. The excess material will be in places it's not needed, where on more expenisve frames tubes are butted and treated to remove this excess material, resulting in a lighter and more responsive frame.

Also cheaper and heavier will mean a lower grade of aluminium, which in laymans terms will be more likely to snap.
