ZCuAl10Fe3 Slide Plate: Characteristics and Applications, Bronze bushings with graphite inserts Plate, Bronze bush with graphite inserts, ZCuAl10Fe3

ZQAL9-4 is a cast aluminum-bronze material with a chemical composition of aluminum 10% and iron 3% (ZCuAl10Fe3). This material has high strength, good friction reduction and good corrosion resistance. Common applications include high-strength, wear-resistant parts, bearings, etc.

Bronze bushings with graphite inserts are specialized bearings designed for high-performance applications where traditional lubrication methods may be inadequate. These bushings combine the strength and durability of bronze with the self-lubricating properties of graphite, making them ideal for various industrial environments.

The ZCuAl10Fe3 slide plate, also known as a bronze wear plate, is an aluminum bronze alloy containing approximately 10% aluminum and 3% iron, with the remainder primarily being copper and trace elements. This alloy exhibits excellent mechanical properties, wear resistance, and corrosion resistance, making it especially suitable for manufacturing components used in harsh environments such as seawater, salt mist, and acidic media. When this alloy is used to create self-lubricating plates, solid lubricants like graphite or molybdenum disulfide (MoS2) are often embedded to further enhance its anti-friction and wear-resistant properties, making it ideal for low-speed, heavy-load applications where continuous lubrication is not feasible. Below are some characteristics and applications of the ZCuAl10Fe3 self-lubricating plate:

Characteristics

  • High Strength and Hardness: The high strength and hardness of aluminum bronze allow it to withstand significant loads, offering superior wear resistance compared to standard copper alloys.
  • Excellent Corrosion Resistance: This alloy performs exceptionally well in marine environments and saline media, making it suitable for applications in offshore platforms and ships.
  • Self-Lubricating Properties: By embedding solid lubricants, the slide plate can reduce friction and wear even in the absence of external lubrication, thereby extending its service life.
  • High-Temperature Resistance: Aluminum bronze maintains good thermal stability, allowing it to retain its mechanical properties at elevated temperatures.
  • Good Casting and Machining Properties: The alloy can be easily manufactured into complex shapes to meet specific design requirements.

Applications

The ZCuAl10Fe3 self-lubricating plate is utilized across various industries and has received positive feedback from users.

  • Marine Industry: Used in components such as rudder bearings, pump shaft sleeves, and propeller shaft sleeves, particularly in parts that come into contact with seawater.
  • Petrochemical Industry: Suitable for wear-resistant components in valves and pumps, as well as sliding parts that operate in corrosive media.
  • Power Industry: Employed in generator slip rings and conductive sliding blocks, leveraging its good electrical conductivity and wear resistance.
  • Heavy Machinery: Found in wear-resistant sliding guides and support bearings in large equipment.
  • Metallurgical Equipment: Used in guide rails and rolling guides for continuous casting machines, known for their high-temperature and wear resistance.

When selecting ZCuAl10Fe3 self-lubricating plates, it is essential to consider specific application environments and operational requirements, including dimensions, shapes, and types of lubricants. Consulting with experts can help ensure that the product meets design and performance needs.
