ASTM B111 C61400 seamless copper tube material overview
C61400 is an aluminum bronze alloy specified in the American Standard (ASTM B150) and is a high-performance copper-based material. This alloy uses a copper matrix, reinforced by the addition of aluminum, iron, and nickel. It combines excellent mechanical properties with corrosion and wear resistance, making it widely used in high-load, high-wear environments in the industrial sector.
Chemical Composition of ASTM B111 C61400 Heat Exchanger Copper Tubing
The typical chemical composition of C61400 is as follows (by weight):
- Copper (Cu): The balance (approximately 85% to 90%) acts as a matrix, providing good electrical and thermal conductivity.
- Aluminum (Al): 8.0% to 11.0%, forming an alumina protective layer that enhances corrosion resistance and strength.
- Iron (Fe): 2.0% to 4.0%, refining the grain size and enhancing wear resistance. - Nickel (Ni): ≤1.0%, improves high-temperature performance and stress corrosion resistance.
- Trace elements such as manganese (Mn) and zinc (Zn) further optimize processing performance.
Physical and Mechanical Properties of ASTM B111 C61400 Copper Tube
1. Mechanical Properties:
- Tensile Strength: ≥550 MPa, hardness reaches HB 170-220, strength close to that of medium-carbon steel.
- Elongation: ≥15%, combining good ductility and toughness.
2. Corrosion Resistance:
- Excellent performance in seawater, acidic, and alkaline environments, resisting erosion corrosion and cavitation erosion.
3. Other Properties:
- Low thermal conductivity, suitable for high-temperature friction conditions; non-magnetic, suitable for electrical equipment.




Typical Applications
1. Marine Engineering: Ship propellers, pump and valve components, seawater pipelines, to resist salt spray corrosion.
2. Heavy Industry: Wear-resistant parts such as bearings, gears, and bushings, suitable for high loads and frequent friction. 3. Chemical Equipment: Sealing rings, agitators, resistant to acid and alkali corrosion.
4. Energy: Fasteners and turbine blades for nuclear and thermal power plants.
Processing and Precautions for ASTM B111 C61400 Copper Plumbing
- Forming Process: Suitable for hot forging, cold working, and precision casting, but the aluminum content must be controlled to avoid hot brittleness.
- Weldability: Specialized welding consumables are required, and preheating to above 300°C is required to reduce the risk of cracking.
C61400 aluminum bronze, with its combination of high strength, wear resistance, and corrosion resistance, is an ideal material for demanding working conditions. Its balanced composition and processing ensure long-term reliability and cost-effectiveness in industrial applications.
