C61400 Aluminum Bronze: A Comprehensive Analysis of a High-Strength, Wear-Resistant Alloy

ASTM B111 C61400 copper pipe is a copper-aluminum-iron alloy, part of the high-strength aluminum bronze family. Widely favored in the industrial sector for its excellent mechanical properties and wear resistance, C61400 differs from C64200 in that it contains a higher ratio of aluminum to iron, resulting in a unique combination of properties.

 

Basic Properties of ASTM B111 C61400 Copper Tube

Chemical Composition:
Copper (Cu): 86-89% (primary matrix)
Aluminum (Al): 6.0-8.5% (primary alloying element)
Iron (Fe): 2.0-4.0% (for enhanced strength and wear resistance)
Manganese (Mn): ≤0.50% (minor addition)
Zinc (Zn): ≤0.50% (residual element)
Lead (Pb): ≤0.02% (strictly controlled)

 

Physical Properties:
Density: 7.89 g/cm³ (slightly lighter than C64200)
Melting Point: approximately 900-940°C
Electrical Conductivity: 10-15% IACS (relative to pure copper)
Thermal Conductivity: 45-50 W/(m·K)
Coefficient of Thermal Expansion: 17.5×10⁻⁶/°C (20-300°C)

 

ASTM B111 Mechanical Advantages of C61400 Copper Plumbing

Typical Mechanical Properties:
Tensile Strength: 550-700 MPa (Higher than ordinary bronze)
Yield Strength (0.2% offset): 275-450 MPa
Elongation: 15-25% (Good ductility)
Hardness: HRB 75-95 (Can be increased by heat treatment)
Fatigue Strength: Approximately 240 MPa (10⁸ cycles)

 

Unique Property Combination:
High strength-to-weight ratio: Specific strength approaches that of some steels
Excellent wear resistance: Ideal for sliding friction applications
Impact toughness: Withstands dynamic loads
Seizure resistance: Resists seizure when mating with steel components
Work Hardening Capability: Cold working significantly increases hardness

Low-Temperature Toughness: No Brittleness at -196°C
Oxidation Resistance: Forms a Protective Oxide Film in Hot Air

 

Processing and Manufacturing of ASTM B111 C61400 Type K Copper Pipe

Forming Process:
Hot Working: Optimum Hot Working Temperature: 700-850°C
Cold Working: Suitable for Cold Work Hardening with Moderate Deformations
Casting Properties: Good Flowability, Shrinkage Approximately 1.8%
Machinability: 70% (Based on 100% free-cutting brass)

 

Jointing Technology:
Weldability: Suitable for TIG and MIG welding
Brazing: Suitable for silver-based brazing filler metals
Mechanical Connection: Suitable for threaded and riveted connections

 

Heat Treatment:
Annealing: Stress relief at 600-700°C
Aging: Precipitation hardening possible
Stress relief: Hold at 260-370°C followed by slow cooling

Packaging and shipping

 

GNEE offers professional packaging for exported copper pipes. First, we apply anti-rust oil and plastic film to prevent oxidation. Then, we securely strap with steel straps and add corner protectors. Finally, we place the pipes on wooden pallets and reinforce them with iron or wooden boxes, ensuring they are moisture-proof and impact-resistant during ocean transport, while facilitating easy loading and unloading. All packaging meets export standards.
