Dimensional Specifications (Rod Shape)
C63000 rods are available in round, square, hex, and flat shapes, with the following size ranges:
International Standards
C63000 rods comply with the following key standards:
ASTM B150/B150M
Specifies requirements for aluminum bronze rods, bars, and shapes.
Covers temper designations (e.g., HR50, M20, O60) and testing protocols for mechanical properties and corrosion resistance .
EN 12163 (CuAl10Ni5Fe4/CW307G)
European standard for nickel-aluminum bronze rods, equivalent to C63000 .
JIS H3250 (C6300)
Japanese Industrial Standard for copper alloy rods
AMS 4640
Aerospace Material Standard for bars and forgings in high-strength applications .
MIL-B-16033
U.S. military specification for naval and aerospace components .
Key Applications
Aerospace: Landing gear bushings, thrust washers, bearings .
Marine: Propeller shafts, pump components, seawater valves .
Industrial: High-strength bolts, nuts, and wear-resistant machinery parts .
Processing Notes
Hot Working: Readily forged and machined (forgeability rating: 75) .
Cold Working: Limited due to rapid work hardening; stress-relieving recommended post-processing .
Detailed Chemical Composition of C63000 Copper
C63000 (UNS C63000) is a nickel-aluminum bronze alloy with a complex chemical composition designed for high strength and corrosion resistance. The chemical composition ranges are as follows :
Key Notes:
- The alloy is primarily copper-based, with aluminum and nickel as critical strengthening elements.
- Trace elements like Pb, Zn, and Sn are tightly controlled to avoid compromising mechanical properties
Mechanical Properties of C63000 Copper
C63000 exhibits excellent mechanical performance, particularly in high-stress and corrosive environments. Below are the key mechanical properties based on ASTM B150 and other standards :
1. Tensile and Yield Strength
2. Ductility and Hardness
3. Elastic and Thermal Properties
4. Fabrication and Processing
- Machinability: 30% (relative to free-cutting brass UNS C36000)
- Hot Working: Good formability at 788–927°C (1450–1700°F)
- Cold Working: Poor; not recommended for severe cold-forming operations
- Annealing: Performed at 593–704°C (1100–1300°F) to relieve stresses
Production process
Smelting and ingot casting: waste brass, copper and zinc ingots are used as raw materials, smelted in an industrial frequency furnace, and copper liquid is formed after impurities are removed, and then ingots are made through continuous casting.
Hot processing: The ingot is formed into a bar through a hot extrusion process. Some processes will be combined with stretching or polishing to improve dimensional accuracy.
Heat treatment: including annealing (such as quenching and tempering) to optimize hardness and mechanical properties.
Subsequent processing: may involve stamping, turning, grinding and other steps to produce parts of specific shapes.
Product advantages
High strength and wear resistance:
Tensile strength can reach 680-760 MPa, yield strength 470 MPa, hardness 180-250 HB, suitable for high load scenarios.
Excellent wear resistance, suitable for manufacturing wear-resistant parts such as bearings, gears, and bushings.
Corrosion resistance:
It exhibits excellent corrosion resistance in seawater, atmosphere and high temperature environments, especially suitable for marine engineering and chemical equipment.
Excellent thermal performance:
High thermal conductivity (39.1 W/mK), low thermal expansion coefficient (16.2×10⁻⁶/°C), good thermal stability, suitable for high temperature environment.
Good processing performance:
Can be hot formed, welded, brazed and cold processed, with good formability, suitable for complex parts manufacturing.
Spark-free characteristics:
As a spark-free tool material, it is suitable for flammable and explosive environments.
