Properties:

CDA 954 Aluminum Bronze is a high-strength, wear-resistant copper alloy commonly used for bushings, bearings, and other components subjected to heavy loads and harsh environments. It is part of the CDA (Copper Development Association) series and is known for its excellent mechanical properties, corrosion resistance, and durability.

• High Strength: Offers superior mechanical strength compared to many other bronze alloys.
• Wear Resistance: Excellent resistance to wear, making it ideal for bushings and bearings.
• Corrosion Resistance: Resists corrosion in various environments, including seawater and chemical exposure.
• Machinability: Can be machined to precise tolerances, though it requires appropriate tools and techniques.
• Load-Bearing Capacity: Suitable for high-load applications due to its hardness and toughness.

 

Fabrication and Machining

• Machining: Can be machined using standard techniques, but requires sharp tools and adequate cooling due to its hardness.
• Welding: Weldable using gas tungsten arc welding (GTAW) or gas metal arc welding (GMAW), though preheating and post-weld heat treatment may be necessary.
• Forming: Can be formed using hot or cold working methods, depending on the application.

Centrifugal casting technology for Aluminum Bronze Bushings enables the production of large-scale components such as copper bushings, copper sleeves, and copper worm gears. This method can handle single castings weighing up to 3 tons with diameters reaching 2 meters. The process ensures excellent product density, and the mechanical properties of the castings-including hardness, tensile strength, and wear resistance-are significantly superior to those achieved through traditional molding techniques.

 

Advantage of CDA954 Aluminum Bronze Bushing

Centrifugal casting for CDA954 Aluminum Bronze Bushings involves pouring molten metal into a rotating mold, where the axis of the solidified copper casting aligns with the mold's rotation axis. Under centrifugal force, the metal crystallizes directionally from the mold wall toward the inner surface of the casting, causing impurities like slag, gas, and inclusions to gather on the inner surface. This results in a fine, defect-free structure throughout the rest of the casting, free from issues such as porosity, shrinkage cavities, or slag inclusions. As a result, the mechanical properties of the casting are significantly enhanced.
