Copper rectangular bar (also known as flat bar) has excellent thermal and electrical conductivity and is naturally corrosion resistant. It is the purest grade of oxygen-free copper and has much tighter limits on impurities than other grades. Copper rectangular bar can be soldered and brazed, but it cannot be heat treated. It’s 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 Metric Metal, we offer copper flat bar in 110 grade in a variety of sizes.
