Don't mistake the purity of copper bars with the copper wiring you can buy from your local hardware store. Generic copper wiring has lower purity, being alloyed with other metals to achieve particular characteristics needed for the application. Copper bullion bars, on the other hand, are usually sold with a 99.9% copper consistency.

Copper bars come in different shapes as well. One of the most popular choices for investors is the copper cube. It makes for an interesting display piece as well as a good investment opportunity.


Copper bars also come in a variety of sizes and weights. A diversity of items with different price points can be useful in your holding, particularly if the metal should be needed for barter and trade. You can find 99.9% copper bars as light as one-ounce pieces and as heavy as 10-pound bars.
