Short answer: Weight matters because scrap is bought by the kilogram or tonne, but heavier does not automatically mean more valuable, since a heavy piece of steel is generally worth less per kilogram than a lighter piece of copper or brass, and a heavy item that is mostly concrete, glass or other non-metal material may be worth very little once those parts are deducted.

List Free →Why metal type matters as much as weight
A kilogram of copper is worth many times a kilogram of steel, so the type of metal can outweigh the weight difference.
Why non-metal parts reduce the value
Concrete, glass, plastic and wood are not paid for as metal, so an item that is heavy because of those parts may pay far less than it looks.
How to estimate sensibly
Think about how much of the weight is actually clean metal and which metal it is before you assume a load is worth a lot.
