C46400 Naval Brass is a copper-zinc-tin alloy specifically engineered for service in both fresh and saltwater environments. By adding a precise amount of tin to the brass matrix, C46400 gains a high resistance to dezincification, a common form of corrosion that weakens standard brass in marine settings. This makes it an essential material for marine hardware, subsea components, and structural naval applications.
At Standard Metals, Inc., we provide C46400 Naval Brass that meets rigorous industrial standards, ensuring long-term durability in corrosive, moisture-rich environments.
Certified Specifications
Our inventory is managed to satisfy the primary benchmarks for domestic and international maritime engineering:
- ASTM B21: The standard specification for Naval Brass rod, bar, and shapes.
- DFARS Compliant: All material is produced in the USA or DFARS-approved countries to satisfy Department of Defense procurement requirements.
Engineering Advantages of C46400
- Dezincification Resistance: The addition of tin prevents the selective leaching of zinc, preserving the structural integrity of the metal in saltwater.
- High Machinability: Known for excellent hot formability and ease of machining, which reduces production costs for complex fasteners and fittings.
- Structural Strength: Offers higher strength and rigidity than standard yellow brass, maintaining reliability under pressure.
- Versatile Finishing: Responds exceptionally well to drawing, forming, and heading processes.
Marine & Industrial Applications
C46400 is frequently specified for components where moisture resistance and strength are critical:
- Marine Hardware: Propeller shafts, turnbuckles, and marine decorative trim.
- Subsea Fasteners: Bolts, nuts, and specialized marine valves.
- Industrial Equipment: Condenser components, heat exchanger parts, and precision-turned fittings.
- Aerospace: Specialized bushings and wear-resistant fittings in non-magnetic environments.
