UNS C23000 Red Brass Alloy Pipes / Tubes
C23000 red brass 85% copper – 15% zinc – has very good resistance to corrosion and dezincification. C230 pipe is used in hot water lines, especially circulating systems, as the corrosiveness of any water increases with a rise in temperature. Red brass is the most durable of all metals for the plumbing industry and commercial water pipe applications. It is excellent for resistance to dezincification and season cracking which most high copper brasses are known for. Dezincification Resistant Alloys (also known as DZR or DR Alloys) such as Red Brass C352 has a small amount of arsenic added to the alloy in order to prevent chlorinated water from leaching the zinc from your plumbing products which eventually leads to the weakening and cracking of your plumbing products.
Red brass is also specified for underground service lines since it offers great corrosion resistance to all types of potable waters, and has moderate strength and good retention of spring properties.
