C71500 Copper Nickel, or 70/30 Cupro Nickel, is the definitive alloy for critical marine environments where failure is not an option. Known for its exceptional resistance to seawater corrosion, stress cracking, and biofouling, this alloy provides the structural integrity required for high-pressure naval systems.
At Standard Metals, Inc., we specialize in supplying C71500 that meets rigorous Military Specifications (MIL-SPEC) and ASTM B151 standards, ensuring full compliance for defense and aerospace contractors.
Certified Quality Standards
We maintain a robust inventory of 70/30 Copper Nickel tested to the industry’s most demanding Specifications:
- ASTM B151: Standard specification for Copper-Nickel-Zinc Alloy (Nickel Silver) and Copper-Nickel Rod and Bar.
- Military Specifications (MIL-SPEC): Specialized sourcing for naval and defense applications.
- DFARS Compliant: All material is produced in the USA or DFARS-approved countries.
| Feature | Benefit for Marine Engineering |
|---|---|
| High Nickel Content (30%) | Provides maximum resistance to high-velocity seawater flow. |
| Excellent Weldability | Simplifies fabrication for complex piping and Waterjet Cutting components. |
| Antimicrobial Surface | Naturally prevents the attachment of marine organisms (Biofouling). |
| Thermal Stability | Maintains mechanical properties across a wide temperature range. |
