Centrifugal casting is a technique often used in the manufacturing of cylindrical parts like bushings and bearings. It involves pouring molten metal into a rotating mold, which creates a centrifugal force that distributes the metal uniformly around the mold. This process is advantageous for producing high-density, defect-free components with fine-grain structures and superior mechanical properties.

Copper Standards

In the context of copper alloys, several standards are commonly referred to:

1. ASTM (American Society for Testing and Materials):
   • ASTM B505: Continuous Cast Bronze
   • ASTM B271: Centrifugally Cast Bronze
   • ASTM B584: Standard Specification for Copper Alloy Sand Castings
2. EN (European Norms):
   • EN 1982: Copper and copper alloys – Ingots and castings
   • EN 12420: Copper and copper alloys – Forged, hot-pressed, rolled, and upset finished products

Custom Bronze Graphite Bushings

Custom bronze graphite bushings combine the properties of bronze and graphite to provide excellent lubrication, especially in high-load and low-speed applications. These bushings are often used in environments where traditional lubricants would be impractical. The bronze matrix provides structural support, while the graphite inclusions offer self-lubricating properties.

Benefits:

• Reduced Maintenance: Self-lubricating nature reduces the need for frequent maintenance.
• High Load Capacity: Suitable for heavy-duty applications.
• Corrosion Resistance: Bronze alloys provide good resistance to corrosion.
• Wear Resistance: Excellent wear characteristics due to the presence of graphite.

Common Applications:

• Industrial machinery
• Automotive components
• Marine equipment
• Aerospace applications

Custom Manufacturing Process

1. Design Specification: Define the dimensions, material composition, and performance requirements.
2. Material Selection: Choose the appropriate bronze alloy and graphite content.
3. Casting: Utilize centrifugal casting or another suitable method to produce the initial bushing shape.
4. Machining: Precision machining to achieve the final dimensions and tolerances.
5. Quality Control: Inspect the bushings for defects, dimensional accuracy, and performance characteristics.
