Guangdong Metal Corporation is a leading Admiralty Brass Tubes - C44300 manufacturer and supplier.
C44300 Admiralty Brass, also sometimes referred to as Arsenical Brass, is copper that is alloyed with tin and zinc. Inhibited Admiralty Brass tubes – C44300 - has good corrosion resistance and is specially used for tubing of steam condensers cooled with fresh, salt or brackish water. Admiralty metal tubes are also used for heat exchangers in oil refineries, in which corrosion from sulfur compounds and contaminated water may be very severe, and for feed-water heaters and heat-exchanger equipment as well as other industrial processes.
Brass C44300 tubes have long been used in heat exchangers and condensers because of the good corrosion resistance and excellent heat transfer characteristics. Inhibited Admiralty Brass has found use in fresh, brackish and salt water applications, as well as oil and gas systems, where its combination of corrosion resistance, heat transfer rates and lower material cost is valued. C44300 brass is most commonly stocked in tube and plate form.
