Tin-phosphor bronze bushings are suitable for use in humid environments, such as hydraulic equipment and cooling tower sliding parts, primarily due to their outstanding corrosion resistance and other compatible performance characteristics. Details are provided below:
Rust Resistance of Tin-Phosphor Bronze
Tin-phosphor bronze is a bronze alloy containing tin and phosphorus. It forms a stable oxide film in humid environments, resisting corrosion from corrosive media such as freshwater, seawater, and some humid air containing acids and alkalis. Therefore, it is suitable for hydraulic equipment exposed to flowing water and cooling towers exposed to humid, vaporous conditions, preventing rust from causing bushing failure or disrupting operation.
Other Compatible Properties
Low Friction Coefficient: Tin-phosphor bronze's low friction coefficient facilitates the operation of sliding parts in hydraulic equipment and cooling towers, reducing energy loss and preventing the adverse effects of frictional heat accumulation. Furthermore, it is compatible with a variety of lubricants, maintaining low friction even when lubrication is insufficient.
Excellent Wear Resistance: This type of bushing offers excellent wear resistance and performs well under high loads and frequent movement. Rotating shafts in hydraulic equipment and rotating or sliding components in cooling towers frequently rub against bushings during long-term operation. Tin-phosphor bronze bushings can extend their service life.
High strength and toughness: They can withstand the impact loads and pressure fluctuations associated with hydraulic equipment operation. Their toughness makes them less susceptible to cracking or breakage caused by vibration and frequent starts and stops, ensuring reliable service in the sliding parts of the equipment.
Common Grades and Specific Advantages
ZCuSn10P1: Contains approximately 10% tin and 1% phosphorus, offering outstanding hardness, wear resistance, and fatigue strength. It is suitable for high-load (>20 MPa) and high-speed (>8 m/s) sliding applications, such as high-power hydraulic pumps and high-power cooling tower fans.
ZCuSn5Pb5Zn5: Contains 5% tin, 5% lead, and 5% zinc, offering excellent castability and a dense structure. The lead enhances self-lubrication, enabling operation in dirty and humid conditions. It is suitable for sliding parts with poor lubrication conditions or exposure to impure moisture.
