Copper plumbing and electrical main wires are 99.95% pure.
Copper tubing for heat exchangers can be alloyed with zinc, aluminum, or nickle. Rarely, it can also be 99.95% pure copper.
There are several grades of copper, and each of which have different allowance of other metals.

| So does that mean #2 and #3 are progessively less pure? |

| Aluminum cans are made of 1100 aluminum alloy. That is a minimum of 99% pure aluminum. |

| Actually the sides and bottom of aluminum beverage cans are made of alloy 3004 or 3104 (~98.2% Al) and the tops are made of 5182 (~95.2% Al). You must be logged in to see this link. is a great place to look up alloy compositions and material properties once you know what you're looking for. |
