When it comes to selecting materials for heavy-duty machinery, choosing the right components can drastically enhance the performance and longevity of your equipment. One such component that plays a crucial role in many industrial applications is the bushing. Today, we’ll dive deep into the features and benefits of the large bronze bushing with graphite, specifically the full split flange bushing made from ASTM B271 UNS C93700.

What is ASTM B271 UNS C93700?

C93700, also known as SAE 64, is a highly utilized high lead tin bronze alloy in bearings, bushings, and various mechanical components subjected to heavy loads, high speeds, and elevated temperatures. Its popularity stems from exceptional wear resistance and good corrosion resistance.

This American standard lead bronze material closely aligns with international standards such as CuPb10Sn10, the Japanese standard LBC3, the British standard LB2, and the German standard G-CuPb10Sn.

ASTM B271 UNS C93700, commonly known as High-Leaded Tin Bronze, is a robust bronze alloy well-known for its durability and excellent wear resistance. The specification ASTM B271 covers centrifugal castings made from copper-based alloys and is w

C93700 is a type of bronze alloy known as leaded tin bronze. It is also commonly referred to as SAE 64. This bronze alloy is composed of the following elements:

  • Copper (Cu): 80.0% to 85.0%
  • Tin (Sn): 6.0% to 8.0%
  • Lead (Pb): 6.0% to 8.0%
  • Zinc (Zn): 0.50% max
  • Iron (Fe): 0.10% max
  • Phosphorus (P): 0.05% max

Leaded tin bronze (C93700) is known for its good machinability, excellent wear resistance, and good corrosion resistance. It is often used in bearing applications where these properties are critical, such as in bushings, thrust washers, and wear plates.

Key Properties:

  • High load-carrying capacity
  • Good fatigue resistance
  • Good anti-friction properties
  • Resistance to corrosion and wear

Centrifugal Cast Bronze Bearing

The C93700 bronze bearing, often referred to as High-Leaded Tin Bronze or 80-10-10 Bronze, is a popular bronze alloy used in the manufacturing of bearings. This alloy stands out for its superior machinability, effective anti-friction characteristics, and decent resistance to corrosion from seawater and brine. Composed of 78.00% to 82.00% copper, 8.00% to 11.00% lead, and 9.00% to 11.00% tin, the C93700 alloy contains a lead percentage ranging from 7% to 30%. The lead serves as a lubricant, enhancing the alloy’s machinability and anti-friction properties.

C93700 bronze bearings are particularly suitable for scenarios where lubrication might be lost. They excel in environments contaminated with dirt and other foreign substances. Thanks to the high lead content, the alloy can mold around foreign particles, thereby safeguarding the wear surface of mating components, like shafts.

These bearings are noted for their exceptional wear resistance, especially in conditions involving high speed, significant pressure, and vibration. They exhibit low friction and are useful in situations with inadequate lubrication or minor misalignments.

C93700 bronze is versatile, finding applications in bearing plates, bearings, bushings for high-speed and high-pressure situations, corrosion-resistant castings, crankshafts, high-speed/heavy-load bearings, impellers, machine parts, maintenance parts for steel mills, pressure-tight castings, pumps, slide guides for steel mills, and large bearings for ships.

However, it is important to mention that C93200 SAE 660 Bearing Bronze is often chosen as an alternative to C93700. This is due to its improved mechanical properties, lower cost, and shorter production lead times.

CuSn10Pb10 – RG10 Alloy

CuSn10Pb10, commonly referred to as RG10, is a different bronze alloy. The designation CuSn10Pb10 describes a bronze with:

  • Copper (Cu): Approximately 80%
  • Tin (Sn): 10%
  • Lead (Pb): 10%

This alloy, also known as gunmetal or red brass in some contexts, is used for its combination of corrosion resistance, wear resistance, and machinability. It is typically used in applications where friction and wear are concerns, such as in gears and bearings.

Key Differences

  • Composition: C93700 has a lower percentage of tin and lead compared to CuSn10Pb10.
  • Applications: Both are used in bearings and bushings, but their different compositions make them suitable for slightly different environments and stress conditions.

Both these alloys are excellent choices depending on the specific requirements of the application, including load conditions, environmental factors, and desired longevity of the component.
