CuZn29Sn1 Admiralty Brass Pipe is a copper-zinc-tin alloy that is suitable for use in water-based applications requiring reliable heat transfer and corrosion resistance. Contains about 71% copper, 28% zinc, and 1% tin, plus a small amount of added arsenic which helps prevent dezincification. The material has good thermal conductivity, strength and ease of fabrication and can be used in steam condensers, heat exchangers, feedwater heaters, marine distillers and oil refining equipment. CuZn29Sn1 is used in the European and international material standards for condenser and heat-exchanger tubes. USA Piping Solution is a trusted CuZn29Sn1 Admiralty Brass Pipe manufacturer and supplier who supplies the quality pipe and tube products to marine, power generation, petrochemical and industrial heat-transfer applications, with reliable material certification and testing.
