what's the rank of "weight" only of the following material for a same sized part:

Aluminum < Liquidmetal < Titantium < Iron ?

I think your rank order is correct, but is that what you really want to know?

The weight of the raw material alone does not tell you anything about the strength to weight ratio. A part requiring a specified yield strength ( i.e., how much stress can be applied before the part deforms) will require far less material when made out of liquidmetal than the other materials you listed. So it will not only weigh less, but for some applications the part can also be made thinner - or otherwise dimensionally smaller - using the liquidmetal alloys.

Liquidmetal alloys are truly transformative in nature, and to grasp their potential applications requires a new way of thinking.
