Core Difference
C44300 (Admiralty Brass): The specialist in corrosion resistance. It contains Tin (Sn) and Arsenic (As) for superior performance in corrosive water environments.
C46400 (Naval Brass): The specialist in strength and machinability. It contains more Tin (Sn) but no Arsenic, making it stronger and more suitable for mechanical components.
Detailed Comparison Table
| Feature | C44300 (Admiralty Brass) | C46400 (Naval Brass) |
|---|---|---|
| Common Name | Admiralty Brass, Arsenical Brass | Naval Brass, Shipbuilding Brass |
| Chemical Composition | Cu: 70-73%, Zn: Remainder, Sn: 0.8-1.2%, As: 0.02-0.06% | Cu: 59-62%, Zn: Remainder, Sn: 0.5-1.0% |
| Key Element | Arsenic (As) - provides superior dezincification resistance. | Higher Copper & Tin Content - provides greater strength. |
| Primary Property | Excellent Corrosion Resistance, especially in seawater. Good erosion resistance. | High Strength, Good Hot Workability, Excellent Machinability. |
| Corrosion Resistance | Superior. The arsenic addition specifically inhibits dezincification, making it the best choice for stagnant or slow-moving seawater. | Good, but less resistant to dezincification than C44300. Not recommended for stagnant water. |
| Mechanical Strength | Good (Typical Tensile: ≥ 325 MPa) | Higher (Typical Tensile: ≥ 414 MPa) |
| Machinability | Fair to Good (~30% of Free-Cutting Brass) | Good (~40% of Free-Cutting Brass) |
| Typical Applications | Heat Exchanger Tubes, Condenser Tubes, Desalination Plant Tubes. | Ship Propellers, Shafts, Marine Hardware, Valve Stems, Pump Parts. |
| Form | Primarily supplied as Tubes and Pipes. | Primarily supplied as Rods, Bars, Forgings, and Plates. |
How to Choose Between Them?
The choice boils down to the primary requirement of your application:
Choose C44300 (Admiralty Brass) if:
Your application involves heat transfer in seawater or brackish water (e.g., condensers, heat exchangers).
The environment is highly corrosive and resistance to dezincification is the top priority.
The component is primarily a tube or pipe carrying water.
Choose C46400 (Naval Brass) if:
You need a strong, tough material for structural or mechanical marine components (e.g., propeller shafts, turnbuckles, bolts, valve stems).
The part requires significant machining or hot forging.
The component is subject to high mechanical stress and wear.
