UNS C44300 Admiralty Brass Tube PDF
Admiralty brass and naval brass
Admiralty brass and naval brass are similar alloys, but admiralty brass has a higher resistance to dezincification due to a tin addition, making it ideal for heat exchangers and condenser tubing in corrosive environments. Naval brass is generally stronger and harder, and is better for applications like structural components, fasteners, and marine hardware where strength is the priority.
admiralty brass pipe vs naval brass pipe
| Feature | Admiralty Brass | Naval Brass |
|---|---|---|
| Primary Composition | Copper, zinc, and tin | Copper, zinc, and tin |
| Key Advantage | Superior resistance to dezincification and excellent corrosion resistance in seawater | Higher strength and hardness |
| Best For | Heat exchangers, condenser tubes, and other applications in corrosive water | Structural components, fasteners (nuts, bolts, rivets), marine hardware, propeller shafts, and condenser plates |
| Strength | 310–380 MPa | 250–300 MPa |
Key Comparison Table
| Feature | Admiralty Brass Pipe (C44300) | Naval Brass Pipe (C46400) |
|---|---|---|
| Primary UNS Alloy | C44300 | C46400 |
| Typical Composition | 71% Cu, 28% Zn, 1% Sn | 60% Cu, 39% Zn, 1% Sn |
| Main Purpose | Heat Transfer (Condenser/Heat Exchanger Tubes) | Structural/Mechanical (Shafts, Valves, Fasteners) |
| Property Emphasis | Superior corrosion resistance, good thermal conductivity | Higher strength, good wear resistance, decent corrosion resistance |
| Common Pipe Use | Yes, the standard material for this application. | Less common for thin-wall heat transfer tubes; used for heavier-wall pipe fittings and components. |
