C44300 ADMIRALTY BRASS

C44300 ADMIRALTY BRASS

C44300 Admiralty Brass, also sometimes referred to as Arsenical Brass, is copper that is alloyed with tin and zinc.
Brass 443 tubes have long been used in heat exchangers and condensers because of the good corrosion resistance and excellent heat transfer characteristics of C443. Inhibited 44300 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.
