COPPER ALLOY ALUMINUM BRONZE DISC ASME SB171 C61400 FORGED DISC
ASME SB171 C61400 refers to a specific copper alloy material under the ASTM B171/B171M standard, which covers copper-alloy plate and sheet for pressure vessels, condensers, and heat exchangers.
Key Details:
DISC (indicating it is supplied in a disc shape, likely for machining into flanges, valves, or other circular components).
Applications:
Standards & Equivalents:
- ASTM B171 / ASME SB171 (same standard, ASME adopts ASTM for pressure vessel use).
- UNS C61400 (Unified Numbering System).
- Similar alloys in other standards: DIN CuAl8, EN 1982-CuAl8Fe3.
1. Mechanical Properties (Typical for C61400)
| Property | Value (Annealed) | Value (Hardened) |
| Tensile Strength | 550–690 MPa (80–100 ksi) | 690–830 MPa (100–120 ksi) |
| Yield Strength (0.2%) | 240–310 MPa (35–45 ksi) | 480–620 MPa (70–90 ksi) |
| Elongation (%) | 25–35% (annealed) | 5–15% (cold worked) |
| Hardness(Brinell) | 130-160HB | 190-230HB |
Notes:
- C61400 has excellent wear resistance and high fatigue strength, making it ideal for heavy-load applications.
- Retains strength at elevated temperatures (up to ~400°C/750°F).
2. Heat Treatment & Fabrication
3. Corrosion Resistance
Excellent in seawater, brackish water, and acidic environments (better than most copper alloys).
Resists cavitation erosion, impingement attack, and biofouling.
Used in marine propellers, pump shafts, and offshore oil & gas components.
4. Sourcing & Forms
- Discs are typically cut from rolled plate or forged stock.
- Common Suppliers:
- Metal distributors (e.g., Metalmen, Farmers Copper, Concast Metal Products).
- Specialized mills (e.g., Aviva Metals, Wieland Metals).
- Check Certifications: Mill test reports (MTR) should confirm compliance with ASME SB171.
5. Equivalent Standards
| Standard | Equivalent Designation |
| UNS | C61400 |
| EN (EU) | CuAl8Fe3 (EN 1982) |
| DIN (Germany) | CuAl8Ni2 |
| JIS (Japan) | HBsC3 |
6. Common Applications
- Marine: Propellers, bearings, valve seats.
- Oil & Gas: Subsea components, wellhead parts.
- Industrial: Gears, bushings, heavy-duty fasteners.
