Products Description
Admiralty brass is composed of zinc, copper, and tin. Copper provides improved heat transfer, while zinc offers corrosion resistance. These tubing materials are particularly useful in applications such as condensers and heat exchangers that use fresh, salt, or brackish water for cooling. You'll find them in refineries, power plants, and other industrial applications.
Pump barrels or sucker rod pumps used in oil drilling also use admiralty brass for its corrosion resistance. Although these pumps typically have a service life of only six months to a year, admiralty brass remains a more desirable option due to its longer service life than carbon steel and lower price than materials like Monel 400.
As one of the most commonly used heat exchange alloys, admiralty brass has been in use for over 70 years. Heat exchangers and power plant condensers manufactured and maintained with C44300 admiralty brass have been operating successfully for over 50 years. GNEE has been producing, distributing, testing, and supplying this alloy for over 12 years. C44300 Navy Brass combines copper, zinc, and tin in a low-cost alloy with excellent thermal conductivity and high corrosion resistance. Whether for heat transfer or pump barrel applications, GNEE Navy Brass is an ideal choice. Let us apply our extensive experience in manufacturing this alloy to your next application.
