Production Process of ASTM B111 C61400 Heat Exchanger Copper Tubing
C61400 utilizes vacuum melting technology to ensure uniform composition. Billets are then hot-rolled/forged, and properties are adjusted through cold working or heat treatment. Stringent quality control procedures ensure material density, reduce impurity content, and meet high strength and fatigue resistance requirements.
Core Features of ASTM B111 C61400 Copper Tube
Wear and Corrosion Resistance: Resists pitting and stress corrosion in seawater and acidic media, with a lifespan far exceeding that of ordinary bronze.
High Strength: A tensile strength of up to 1100 MPa after cold working makes it suitable for heavy-load components.
Thermal and Electrical Conductivity: Meets both heat dissipation and electrical conductivity requirements, making it suitable for power equipment.
Processability: Supports various molding processes, including casting, forging, and machining.




Typical Applications
Marine Engineering: Marine propellers, valves, pump bodies, and other seawater-resistant components.
Aerospace: Landing gear bearings and high-temperature fasteners.
Power Equipment: Conductive springs and circuit breaker contacts.
Mechanical Manufacturing: Gears, bearing bushings, and mold inserts.
Industry Outlook
With the acceleration of high-end equipment manufacturing, new energy, and marine development, market demand for high-performance alloys continues to grow. C61400, with its comprehensive performance, has significant potential in the following areas:
Environmental Protection Equipment: Its corrosion resistance makes it suitable for desulfurization and wastewater treatment systems. New energy vehicles: Demand for lightweight motor bearings and connectors.
Smart manufacturing: High-precision transmission components replace traditional steel, reducing energy consumption.
Aluminum bronze C61400, with its irreplaceable performance advantages, is becoming a core material choice in industrial upgrades, and its market penetration is expected to further increase in the future.
