C23000

C23000 brass stands out as the most durable among commercially available metals for water pipes within a practical price range. Its exceptional resistance to dezincification and season cracking, well-known characteristics of high copper brasses, make it an excellent choice. This brass alloy offers moderate strength along with the ability to retain good spring properties. It’s the preferred choice for underground service lines, providing unmatched corrosion resistance against various types of potable water. Beyond its utility, it has become popular in outdoor applications and holds a significant place in modern architectural design, sometimes referred to as Nordic Brass.
