CuZn25Al6FeMn3 bronze graphite plate, Graphite-embedded bronze alloys are engineered to offer self-lubrication and withstand high temperatures, making them ideal for situations where conventional lubrication is impractical or unwanted. These alloys, particularly those made from the CuZn25Al6FeMn3 composition, are recognized for their capability to endure temperatures up to 450°C (842°F), and under specific circumstances, up to 593°C (1100°F). The inclusion of graphite, serving as a solid lubricant within the bronze framework, alongside the distinct properties of the CuZn25Al6FeMn3 bronze alloy—known for its remarkable wear resistance, high capacity for load-bearing, and superior corrosion resistance—enhances their application. The synergy of graphite and this specific bronze alloy results in materials that are highly suited for high-load, low-speed scenarios where traditional lubricants fail, such as in some industrial machines, vehicle parts, and heavy-duty equipment.

For scenarios demanding a bronze alloy that must resist temperatures of at least 450°C, the graphite-incorporated CuZn25Al6FeMn3 alloy stands out. This composition ensures the material’s optimal performance at high temperatures, offering the necessary self-lubrication and resistance to wear for challenging applications.

In essence, the CuZn25Al6FeMn3 bronze-graphite alloy is an optimal choice for various industrial uses requiring a minimum temperature resistance of 450°C. Its high-temperature endurance, coupled with its self-lubricating and wear-resistant characteristics, positions it as a preferred option in environments where conventional lubrication approaches are infeasible or undesired.

The hardness and operating temperatures of various cast bronze alloys are crucial for selecting the appropriate material for specific applications, especially in bearing and structural applications where these properties significantly impact performance and durability. Below is a detailed overview of the hardness (measured in Brinell hardness number) and operating temperature ranges (minimum and maximum) for the specified cast bronze alloys based on the provided information.

Hardness and Operating Temperatures

Key Points:

• Hardness: The Brinell hardness of these alloys ranges significantly, from as low as 55 typical for C93800 to as high as 241 min for C95900. This variation indicates the diversity in the mechanical properties of bronze alloys, making them suitable for a wide range of applications. Hardness affects wear resistance, durability, and the ability to withstand mechanical loads.
• Operating Temperature: All listed alloys have a minimum operating temperature of -450°F, showcasing their excellent performance in extremely cold environments. The maximum operating temperature varies, with some alloys like C95400, C95500, and C95900 capable of handling up to +1200°F intermittently, making them suitable for applications experiencing high temperatures.
• Application Suitability: The choice of alloy depends on the specific requirements of the application, including mechanical load, wear conditions, environmental factors, and required lifespan. For example, alloys with higher hardness and temperature tolerance, such as C95400 and C95900, are well-suited for high-load and high-temperature applications, while those with lower hardness, like C93800, may be more appropriate for applications where wear resistance is less critical.

This comprehensive overview based on the provided data highlights the importance of considering both hardness and operating temperature ranges when selecting a cast bronze alloy for specific applications. These properties, along with other factors like corrosion resistance and machinability, play a critical role in ensuring the optimal performance and longevity of the components made from these materials.

Graphite sliders and wear plates used in preform molds offer a variety of advantages and applications.

Features and Advantages of Graphite Sliders:

• Wear resistance and lubrication: The surface of the graphite sliders features grooves for graphite rods, greatly enhancing their wear resistance and lubrication, thus extending their lifespan.
• High temperature and load capacity: Graphite copper sliders are capable of withstanding high temperatures and loads, suitable for conditions with high temperatures or poor lubrication.
• Oil-free lubrication: Graphite copper sliders transcend the traditional reliance on oil and grease for lubrication, achieving oil-free lubrication which ensures stable and reliable practicality.

Materials and Structure:

• High-strength brass base: The graphite copper slider uses a high-strength brass base, embedded with orderly arranged graphite rods as the friction material. This combination enhances the hardness and wear resistance more than twofold compared to regular copper materials.
• Structural design: The graphite copper slider includes vertical and horizontal copper sliders, which are perpendicular and integrally formed. The horizontal copper slider features positioning holes on its side, with graphite holes on the upper surface and the left side of the vertical copper slider, where graphite rods are inserted.

Applications:

• Injection molding processing: Graphite copper sliders are extensively used in plastic injection molding machines, extrusion structures, automatic switches of high voltage, lifting supports in construction machinery, and in supporting arcs, pulleys, and transmission wheels in hydraulic projects.
• Preform molds: In preform molds, graphite sliders and wear plates are utilized for guide rails and sliders to provide better lubrication and wear resistance.

Market Products:

• Bronze solid graphite slide board: For example, oil-free self-lubricating guide plates and L-type rail sliders made from bronze solid graphite are used as wear plates in preform molds.
• Custom products: Some suppliers offer customized graphite sliders and wear plates to meet specific mold requirements.

In summary, the application of graphite sliders and wear plates in preform molds not only enhances the mold’s wear resistance and lubrication but also extends the mold’s service life, making them suitable for various industrial applications involving high temperatures and heavy loads.
