JoeB, the numbers Kalee gives are resistivities. You are (NOW) both saying the same things but from opposite directions. Your first go was wrong however.
At room temperature, my copy of Kaye and Laby (THE bible of such stuff) gives Aluminium with resistivity of 2.50 with copper given as 1.55 (units ignored to save my head).
