CuZn15-C23000 Red brass is the most durable of all metals for commercial water pipe in the practical price range. Excellent for its resistance to dezincification and season cracking for which the high copper brasses are known. Moderate strength and good retention of spring properties. Specified for underground service lines since it offers greatest corrosion resistance to all types of potable waters. Applications for C230 brass include costume jewelry, fire hose couplings, zippers, condenser and heat exchanger tubes. Popular as an outdoor metal and has found for itself a very important place in modern architecture. Also known as Nordic Brass. The EN equivalent for this alloy is CuZn15. Longda metal produce C23000 brass tube in round and special shapes, packing in straight and LWC.
