Copper flat bar (also known as rectangular bar) has excellent thermal and electrical conductivity and is naturally corrosion resistant. It is the purest grade of oxygen-free copper, and contains 99.99% copper and has much tighter limits on impurities than other grades. Copper flat bar can be soldered and brazed, but it cannot be heat treated. Copper flat bar is a good selection when machining is involved due to its high ductility. Copper is also good for cold and hot forming applications.

Industrial applications of copper flat bar include base plates, bus bars, heat exchanging components, plumbing fittings, automotive spark plugs, and other electrical components.


At Parker Steel, we offer copper flat bar in 110 grade in a variety of sizes. We can also cut material to your size specifications.  For more information, visit our services page or request a quote to start the ordering process today.
