C44300 (Admiralty Brass) is a copper-zinc alloy with enhanced corrosion resistance, primarily used in heat exchangers, condensers, and marine applications.
Composition:
Cu (Copper): 70–73%
Zn (Zinc): Remaining balance
Sn (Tin): 0.9–1.2% (added to improve corrosion resistance)
As (Arsenic): 0.02–0.06% (to inhibit dezincification)
ASME B111:
Title: Standard for Seamless Copper and Copper Alloy Pipe and Tube
Scope: Specifies requirements for seamless tubes made of copper and copper alloys, including dimensions, tolerances, mechanical properties, and testing methods.
C44300 Compliance: Covers chemical composition, temper designations (e.g., O60, H58), and performance criteria.
Corrosion Resistance:
Excellent resistance to saltwater, steam, and industrial cooling fluids due to tin and arsenic additives.
Resists dezincification and erosion-corrosion in high-velocity environments.
Thermal Conductivity: High thermal efficiency (≈109 W/m·K), ideal for heat transfer applications.
Mechanical Properties:
Tensile Strength: 330–450 MPa (depending on temper)
Yield Strength: 125–345 MPa
Hardness: 55–155 HV
Heat Exchangers & Condensers:
Power plant condensers, HVAC systems, and refinery heat exchangers.
Preferred in marine environments due to saltwater resistance.
Marine Engineering:
Seawater piping, shipboard condensers, and desalination systems.
Industrial Cooling Systems:
Chemical processing, oil & gas cooling loops.
Seamless Tube Process: Produced via extrusion or cold drawing to ensure uniform microstructure.
Temper Designations:
O60 (Annealed): Soft, high ductility for forming.
H58 (Hard-Drawn): Higher strength for structural applications.
Mandatory Tests:
Hydrostatic/Pneumatic Testing: Ensures leak-tightness.
Eddy Current Testing (ET): Detects surface defects.
Flattening/Flaring Tests: Validates ductility.
| Alloy | Key Features | Limitations |
|---|---|---|
| C44300 | Superior dezincification resistance | Higher cost vs. C68700 (Arsenical Brass) |
| C68700 | Lower cost, good general corrosion resistance | Less resistant to aggressive marine environments |
| C70600 (Cu-Ni 90/10) | Excellent seawater corrosion resistance | Lower thermal conductivity than brass |
ASME B111 Compliance: Requires certification of chemical composition, mechanical properties, and dimensional tolerances.
Additional Certifications:
ASTM B111: Equivalent to ASME B111 for seamless copper alloy tubes.
EN 12451: European standard for copper alloy seamless pipes.
