Applications Of ZCuPb20Sn5 Cast Lead Bronze Bushing

ZCuPb20Sn5 cast lead bronze finds widespread use in various applications:

Sliding Components:

Thanks to its outstanding self-lubrication, ZCuPb20Sn5 alloy is ideal for manufacturing sliding components such as bearings, bushings, and sliders. This property helps minimize frictional wear and extend the lifespan of these critical parts.

Self-Lubricating Mechanisms:

In situations where lubrication is impractical or challenging, ZCuPb20Sn5’s exceptional self-lubrication comes to the forefront. This makes it suitable for mechanisms that require automatic lubrication even in the absence of traditional lubricants.

Corrosion-Resistant Environments:

Due to its resistance to sulfuric acid corrosion, ZCuPb20Sn5 bronze finds application in environments where exposure to corrosive substances is a concern, such as in chemical processing equipment.

Comparison with ZCuPb15Sn8:

Compared to its predecessor, ZCuPb15Sn8 (15-8) cast lead-tin bronze, ZCuPb20Sn5 has a higher lead content and lower tin content. This composition enhances its performance in terms of sliding and self-lubrication, making it particularly suitable for applications demanding superior self-lubricating capabilities. However, it’s essential to note that ZCuPb20Sn5 may have relatively poorer casting properties, which could necessitate more complex manufacturing processes.

In summary, ZCuPb20Sn5 cast lead bronze bushings offer exceptional self-lubrication, making them well-suited for high-speed bearing applications, crushers, water pumps, and cold-rolling mill bearings. They excel in environments with up to 70MPa loads and are highly corrosion-resistant, making them a valuable choice in demanding industrial scenarios.
