UNS C44300 Admiralty Brass Tube PDF
What is the difference between admiralty brass and naval brass?
Naval Brass is stronger and harder due to higher zinc content. Admiralty Brass offers superior resistance to dezincification. Decision: Specify Admiralty Brass for heat exchanger tubing. Use Naval Brass for structural components like tube plates and fasteners where strength is the primary need.
What is admiralty brass?
Admiralty Brass is a high-performance brass alloy alloyed with tin (0.9–1.2%) and trace elements such as arsenic and iron. Its precise chemistry prevents zinc leaching in seawater and harsh chemicals, making it ideal for tubes, fittings, and components in heat exchangers, condensers, pumps, and valves.
What is navel brass?
Naval brass is the classic marine, high-strength and corrosion-resistant alloy containing 60 percent copper, . 75 percent tin and 39.2 percent zinc. It is widely used in marine construction where strong, corrosive-resistant and hard material is required and is suitable for both salt and fresh water applications.
What are the three types of brass?
| Class | Proportion by weight (%) | Notes | |
|---|---|---|---|
| Copper | Zinc | ||
| Alpha brasses | > 65 | < 35 | Alpha brasses are malleable, can be worked cold, and are used in pressing, forging, or similar applications. They contain only one phase, with face-centred cubic crystal structure. With their high proportion of copper, these brasses have a more golden hue than others. The alpha phase is a substitution solid solution of zinc in copper. It is close in properties to copper, tough, strong, and somewhat difficult to machine. Best formability is with 32% of zinc. Corrosion-resistant red brasses, with 15% of zinc or less, belong here. |
| Alpha-beta brasses | 55–65 | 35–45 | Also called duplex brasses, these are suited for hot working. They contain both α and β' phases; the β'-phase is ordered body-centred cubic, with zinc atoms in the centre of the cubes, and is harder and stronger than α. Alpha-beta brasses are usually worked hot. The higher proportion of zinc means these brasses are brighter than alpha brasses. At 45% of zinc the alloy has the highest strength. |
| Beta brasses | 50–55 | 45–50 | Beta brasses can only be worked hot, and are harder, stronger, and suitable for casting. The high zinc-low copper content means these are some of the brightest and least-golden of the common brasses. |
| Gamma brasses | 33–39 | 61–67 | There are also Ag-Zn and Au-Zn gamma brasses, Ag 30–50%, Au 41%.[36] The gamma phase is a cubic-lattice intermetallic compound, Cu5Zn8. |
| White brass | < 50 | > 50 | These are too brittle for general use. The term may also refer to certain types of nickel silver alloys as well as Cu-Zn-Sn alloys with high proportions (typically 40%+) of tin and/or zinc, as well as predominantly zinc casting alloys with copper additives. These have virtually no yellow colouring at all, and instead have a much more silvery appearance. |
Is naval brass expensive?
Due to its composition and properties, naval brass may be slightly more expensive compared to other types of brass.
