No, copper is NOT cheap, it costs quite a bit more than aluminum pound for pound. Copper has a much lower resistance to electricity than aluminum does. When subjected to the loads household wiring have to deal with, aluminum wiring would have to be prohibitively thick to prevent overheating. Copper provides the best conductivity with the best compactness for the best price.

Find a local metal detecting club. Other than that try parks, old farm houses, beaches, school grounds, vacant lots where houses once stood. Basically anyplace people have been.

Flip them. If they ring, they are pre-1981. Alternatively, drop them one by one onto a hard floor. Again, if they ring, they have the higher copper content.

There are many sites on the internet. geeks.com computer-show.com How much do you wish to spend? 10,000 is a lot, got warehouse? Maybe place ads in newspapers, will pick up your computer scrap for free! Old stuff is cheap, newer stuff costs money. Maybe auctions bid4assets.com? Government auctions sell stuff by the palet, got fork-lift?\nMIKE

My husband went to Lima, Peru about 15 yrs ago and brought me home some beautiful peices of silver.  They mine silver there and it is extremely reasonable.  Maybe you could try searching the web for some wholesalers out of Peru.  Just a thought.  I didn't understand you to say you were going on-line to sell these, do you have a storefront or what?

It depends what you are looking for exactly. You may want to contact your local junk/slavage yard and ask them where they purchase them or even contacting places like Autozone, O'Reilly's and Advance Auto Parts. They might know where to find what your looking for.

1) you can sell your scrap metal to any scrap metal recycler. Do a local seach for scrap metal recycler or recyclers.\n\n2) when you say "metal" building that is a broad description.  I assume you mean a steel buildig possibly with galvanized or aluminum sheeting.  I assume you may even have some copper cable as well.  Each of these types of scrap metal should be separated and sent to the recycler as each type of scrap has a different value.\n\ngo to http://demolition1.blogspot.com for current U.S. Scrap Metal prices
