- Zinc (Zn): 2.0% – 5.0%
- Lead (Pb): 5.0% – 8.0%
Graphite is added to the copper alloy to enhance its self-lubricating properties.
Physical and Mechanical Properties
- The CuSn7Zn4Pb7 copper alloy exhibits moderate strength, good anti-seizure properties, excellent machinability, and moderate corrosion resistance.
- The inclusion of graphite in the bronze bushings provides excellent self-lubricating capabilities, reducing wear and heat generated from excessive friction, thus extending the lifespan of the equipment.
- The melting range of this alloy is approximately 860°C to 1020°C, with a density of 8.8 g/cm³. At 20°C, its electrical conductivity is 7.5 MS/m, and its thermal conductivity is 64 W/(m·K).
Applications
CuSn7Zn4Pb7 graphite bronze bushings are primarily used in industrial applications as wear-resistant and elastic components, such as:
- Bearings: Suitable for various bearing applications due to their durability.
- Bushings: Commonly used in machinery that requires reliable performance under load.
- Sleeves: Ideal for applications where sliding motion occurs.
Due to their excellent electrical conductivity, wear resistance, and self-lubricating properties, graphite bronze bushings are widely utilized in sectors such as:
- Power Generation: In applications requiring high-performance springs, switches, and connectors.
- Aerospace: For components that must withstand demanding conditions.
- Marine: Used in parts that are exposed to seawater and other harsh environments.
Manufacturing Process
The production of graphite bronze bushings involves several steps, including:
- Preparation of Raw Materials: Ensuring high-quality materials are used.
- Casting: Forming the initial shape of the bushings.
- Rough Machining: Shaping the bushings to approximate dimensions.
- Drilling: Creating necessary holes for installation.
- Embedding Graphite: Ensuring a strong bond between graphite and copper.

These bushings, particularly those made from solid bronze, bring together the advantages of robustness, excellent sliding properties, and corrosion resistance. At viiplus.com, we provide high-quality solid bronze shoulder bushings that cater to a variety of applications.
Shoulder Bushings: A Closer Look
Shoulder bushings, characterized by a flange or shoulder at one end, are typically used in applications where precision alignment is required. The shoulder provides a surface for tooling or components to accurately locate against, ensuring proper placement and movement.
Solid Bronze: The Material of Choice
When it comes to material selection for shoulder bushings, solid bronze is a standout choice. Known for its strength, wear-resistance, and long service life, solid bronze is ideal for heavy-duty applications. The material’s resilience against harsh operating conditions and heavy loads makes it an optimal choice for industries such as construction, mining, and heavy machinery.
Lubrication: Enhancing Performance
While solid bronze bushings are known for their excellent sliding properties, the addition of lubricants can further enhance their performance. The use of oil or grease as a lubricant not only improves the sliding properties of the bushings but also reduces wear and prevents corrosion. The lubricant forms a protective film that reduces friction between the bushing and the mating component, extending the service life of both.

Comparing Plain Bearing Materials: A Focus on Solid Bronze Bushings
When it comes to choosing materials for plain bearings, the selection can seem overwhelming. Metals like bronze, brass, steel, and composite materials, all have their unique advantages. However, solid bronze bushings stand out in several ways due to their unique properties and wide range of applications.
Plain Bearing Materials: An Overview
Plain bearings are made from a variety of materials, each with their unique characteristics. Common materials include:
- Metal-Polymer Composite Bearings: These bearings are characterized by their low maintenance, good frictional properties, and ability to work under marginal lubrication conditions. They typically consist of a metal backing with a thin layer of a polymer compound.
- Steel-Backed Bearings: Steel-backed bearings are characterized by their high load capacity and good fatigue properties. They typically consist of a steel backing with a thin layer of a bearing material like PTFE or bronze.
- Brass Bearings: Brass bearings offer good machinability and excellent resistance to corrosion. They are ideal for applications where strength and hardness are required.
Solid Bronze Bushings: Standing Out in the Crowd
While all these materials have their merits, solid bronze bushings have particular properties that make them a popular choice. Unlike composite or layered bushings, they consist of a single material, in this case, bronze alloy. This means that there’s no risk of a sliding or supporting layer wearing off or peeling away over time, which can occur in composite or layered materials.
Solid bronze bushings are renowned for their excellent load-carrying capacity, outstanding wear resistance, and superior performance under varying speed and load conditions. Their exceptional resistance to shock, impact, and corrosion further adds to their durability.
Moreover, these bushings exhibit low friction characteristics and superb heat conductivity, making them a go-to choice for applications with high loads and slow speeds. Additionally, they are easy to machine and install, further enhancing their appeal to various industries.
While the choice of bearing material depends on the specific application, solid bronze bushings offer a wide range of benefits that make them a top contender. At viiplus.com, we specialize in providing high-quality solid bronze bushings tailored to meet your specific needs, ensuring the optimal performance and longevity of your applications.
