Actually, copper weighs a little more than steel.
Copper: 0.295 pounds In^3
Aluminum: 0.098 pounds In^3
Steel: 0.283 pounds In^3
Copper also has the lowest yield strength of all three with steel
being the highest.

The tighter the stuff is squeezed together (like in copper) the

conductor of heat than aluminum.

In light of your statements above, I have two questions:
1. Why is diamond, which is less dense than copper, a better heat
conductor?
2. Why is lead, which is more dense than copper, a worse heat
conductor.
### as I mentioned b4... steel weighs aprx the same as copper...
and doesn't conduct heat worth a damn .2 to 1 ratio for steel
to copper [all the heat trnasfer tables use copper as the
reference = 1] AL is only .57 to 1 Lead is heavy as
hell... and doesn't conduct heat worth banana's.
