bedra 92710
High Leaded Tin Bronze
Characteristics：
bedra 92710 is a high-leaded tin bronze alloy with excellent machinability and good lubricity due to its lead content. High-leaded tin bronzes are ideal for bearing applications.
Typical applications:
It is widely used for general-purpose bearings under moderate pressure, wear-resistant components for rod bushings and wedges, as well as pump impellers and bodies. Additionally, it is employed in steel-backed automotive and aero-engine bushings that are prone to poor lubrication.
