UNS C44300 Admiralty Brass Tube PDF
What is ASTM B111 C44300 copper tubing?
C44300 Admiralty brass tubes have various applications such as being used in power plants, ship repairs, ship building, condensate coolers, tank manufacturing, heat exchangers, vent condensers, turbine oil coolers, evaporators, distillers, vessel manufacturing, water heaters, desalination plants, machine shops, ferrules, refineries, generators, component manufacturing and air coolers. The capabilities of this kind of brass include the likes of: surface machining, assembly and finishing, sawing, waterjet machining, shearing, DFX/CAD drawing, cutting, etc. Admiralty brass, also called Arsenical brass, is also a copper zinc alloy, but it consists of small parts of arsenic and tin. It consists of 1% tin and 30% zinc.
C44300 Admiralty brass condenser tubes are very famous for their superior resistance to corrosion in water that is slow moving, stagnant water, clean seawater and even water that is moderately polluted. It is also resistant to bio-fuels. This type of brass has a very high-thermal conductivity. These types of tubes are available in various sizes and they can be got as semi-finished parts, pre-cut shapes and also in rough-cut pieces. These tubes can be procured as roped, square, hollow, bored, round, oval, half round, reeded, corrugated, quarter round, hollow wire, roped, flexible, hexagonal, thick walled, honed, tapered, rectangle, as well as in small or large diameter.
