Record Copper Prices Prompt Switch To Aluminum

Copper's price surge this year is sparking a switch among manufacturers to another electricity-conducting metal: aluminum.


Makers of automobiles, air conditioners and industrial components are increasingly turning to the much cheaper metal to help offset rising cost pressures as the global economic recovery gains steam.


The difference between the prices of copper and aluminum is now enough to cover the costs of retooling some manufacturing processes and pay for the extra aluminum it takes to conduct the same amount of electricity as copper. (The wall street Journal)
