C62300 aluminum bronze plates are available in the following standard dimensions (custom sizes may also be produced upon request):
- Thickness: 0.5 mm to 80 mm
- Width: 0.5 m to 3 m
- Length: 1 m to 6 m
These dimensions cater to industrial requirements for structural components, corrosion-resistant linings, and conductive elements. Thickness tolerances adhere to general copper plate standards, with allowable deviations calculated based on nominal thickness (e.g., ±1.16 mm for 12 mm thickness)
International Standards
C62300 aluminum bronze plates are governed by the following standards:
- Primary Standard:
- ASTM B150/B150M-2008: Specifies requirements for copper-alloy plates, including chemical composition, mechanical properties, and testing methods
- Equivalent Standards:
- GB/T 5231-2012 (China): Corresponds to C62300 under the designation QAl9-4
- ASME SB150: Adopted for pressure vessel and boiler applications
- ISO 15608: Classifies C62300 under non-ferrous alloy groups for welding procedure qualifications
Detailed Chemical Composition of C62300 Aluminum Bronze
C62300 is an aluminum bronze alloy primarily composed of copper (Cu), aluminum (Al), and iron (Fe), with minor additions of manganese (Mn), silicon (Si), nickel (Ni), and tin (Sn). The chemical composition is standardized as follows:
Key Notes:
- Aluminum (Al) enhances strength, hardness, and corrosion resistance.
- Iron (Fe) refines grain structure and improves mechanical strength
- Trace elements like Mn and Si aid in deoxidation and improve workability
Mechanical Properties of C62300 Aluminum Bronze
C62300 exhibits excellent mechanical properties, making it suitable for demanding industrial applications. The values vary slightly depending on product form (e.g., extruded bars, forgings) and temper conditions (e.g., HR50, TQ50).
Typical Mechanical Properties
Physical Properties
Key Notes:
- High Strength-to-Weight Ratio: Ideal for components like gears and valve stems
- Wear Resistance: Suitable for bearings and bushings in marine and industrial environments

Production process and product advantages of C62300 copper plate:
Production process
Smelting and casting
The main preparation method of C62300 aluminum bronze plate is smelting and casting process. By precisely controlling the ratio of copper (about 82.2%-89.5%) and aluminum (8.5%-10%), and adding elements such as iron and nickel to form an alloy.
Forming process
Extrusion and forging: Suitable for manufacturing parts with complex shapes, forming a dense and uniform microstructure through extrusion or forging, improving strength and corrosion resistance.
Rolling and hot and cold processing: The material has good plasticity and can be cold, hot rolled and formed.
Surface treatment: Some processes may include steps such as degreasing and painting (such as general copper plate process).
Heat treatment
Annealing: 700-750℃ annealing to eliminate internal stress.
Quenching and tempering: After 850℃ water-cooled quenching, 500-550℃ tempering can adjust the hardness to HB 110-178.
Product Advantages
Excellent mechanical properties
High strength: tensile strength ≥490 MPa, yield strength ≥340 MPa, elongation ≥16%.
Wear resistance: high hardness (HB≥100) and light and high strength, suitable for key scenarios such as aviation engine components and bearings.
Corrosion resistance
Excellent corrosion resistance to seawater, chemical media and atmospheric environment, especially in the fields of shipbuilding, marine engineering and petrochemicals.
Excellent processing performance
Supports a variety of processes such as casting, forging, extrusion, welding, and good cutting processability (cutting efficiency up to 20%).
Electrical and thermal conductivity
Electrical conductivity 6.58 MS/m, thermal conductivity 58.6 W/(m·K), suitable for electrical system components and heat exchange equipment.
Lightweight and economical
Density is about 8-9 g/cm³, which is lighter than other alloys, and the cost is lower than stainless steel and nickel-based alloys, with significant cost performance.
Wide range of applications
Aviation: engine components, precision instruments (due to high temperature stability and reliability).
Shipping and petrochemical: valves, pump bodies, propellers and other corrosion-resistant parts.
Electric power and machinery: gears, connectors, mold materials, etc.
