| Notes: Condition "R" = as-rolled / hot-worked. "—" indicates not specified. Size = diameter for bar, OD/WT for tube. Values are indicative; refer to the applicable standard for exact limits. | |||||||
Engineering Note: As Al + Ni + Fe content increases, both strength and hardness rise while elongation decreases. For seawater service, C63000 / QAl10-4-4 and C63200 / QAl11-6-6 are preferred due to superior cavitation and corrosion resistance.
Machining and Fabrication of Aluminum Bronze
Aluminum bronze can be machined using conventional methods. Proper cutting parameters and tooling selection are recommended because of its high strength and hardness.
- CNC machining is suitable for precision components.
- Welding can be performed with suitable filler materials and procedures.
- Forging improves mechanical properties for high-load applications.
- Surface finishing can improve appearance and dimensional accuracy.
Quality Control and Testing
Every aluminum bronze product should undergo strict inspection to ensure chemical composition, mechanical performance and dimensional accuracy.
| Inspection Item | Testing Method | Purpose |
|---|---|---|
| Chemical Composition | Spectrometer Analysis | Confirm alloy grade |
| Tensile Test | Mechanical Testing | Verify strength requirements |
| Hardness Test | Brinell Hardness | Check wear performance |
| Dimensional Inspection | Precision Measurement | Ensure machining accuracy |
Packaging and Transportation
Aluminum bronze products are carefully packed to prevent surface damage, deformation and contamination during transportation.
Plates, bars and tubes are normally protected with moisture-proof wrapping, wooden cases or steel frames according to product dimensions and shipping requirements.
Complete material certificates, inspection reports and packing lists can be provided together with the shipment to support customer quality control procedures.
Aluminum bronze is a copper-based alloy with aluminum as the main alloying element. It provides excellent strength, corrosion resistance and wear resistance compared with many traditional copper alloys.
The main advantages of aluminum bronze include high mechanical strength, excellent seawater corrosion resistance, superior wear resistance, good fatigue resistance and long service life in harsh environments.
Common standards include ASTM B148 for aluminum bronze castings, ASTM B150 for aluminum bronze rod and bar products, and EN 1982 for copper alloy castings.
Common aluminum bronze grades include C95400, C95500, C95800, and CuAl10Fe3. Different grades are selected according to strength, corrosion resistance and application requirements.
Yes. Aluminum bronze has excellent resistance to seawater corrosion, erosion corrosion and cavitation, making it widely used for ship propellers, marine valves, pumps and offshore equipment.
Aluminum bronze generally has significantly higher tensile strength and wear resistance than common brass alloys, making it more suitable for heavy-duty mechanical applications.
Yes. Due to its high hardness, toughness and low friction characteristics, aluminum bronze is widely used for bearings, bushings, gears, valve seats and sliding components.
We can supply aluminum bronze plates, bars, tubes, forgings, castings and customized machined components according to customer drawings and specifications.
Typical aluminum bronze contains approximately 5-12% aluminum, with copper as the balance. Some grades also contain iron, nickel and manganese to improve strength and corrosion resistance.
Yes. Aluminum bronze can be machined using CNC machining and conventional processing methods. Proper cutting tools and parameters are recommended due to its high strength.
Yes. Aluminum bronze can be welded using suitable welding processes and filler metals. Welding procedures should be selected according to alloy grade and service conditions.
Aluminum bronze is widely used in marine engineering, shipbuilding, oil and gas, chemical processing, power generation, mining equipment and general mechanical industries.
Aluminum bronze offers excellent seawater corrosion resistance and lower density, while stainless steel generally provides higher temperature resistance and different mechanical characteristics depending on grade.
Yes. Aluminum bronze products can be customized according to dimensions, chemical composition, mechanical requirements, machining drawings and special application conditions.
Yes. Material certificates including chemical composition analysis, mechanical test reports and inspection documents can be provided according to customer requirements.
Delivery time depends on product type, quantity and customization requirements. Standard sizes can usually be supplied quickly, while customized products require additional manufacturing time.
