IN 1982 CC496K | CuSn7Pb15

BP15 | Bronze Copper Alloy Tin Lead

Available formats: Bars, Tubes, Caps, Plates and Plates.

features

The lead content in the BP15 alloy is between 7 and 30 percent. Tin bronzes with high lead content are free cut and retain favorable thermal conductivity and good lubrication due to lead content.

 

Tin lead bronzes such as BP15 are ideal for bearing applications where there could be a loss of the lubrication limit. These alloys have excellent performance in unforgiving environments where there may be foreign matter, such as dirt and other foreign materials.

 

Alloys with a high lead content can wrap foreign matter due to its malleable nature and, in doing so, protect the wear surface of a coupling part, such as a shaft.

Applications

INDUSTRIAL: bearings, rail motor housings, pumps, industrial centrifuges, machine parts, low friction, moderate pressure bushings, railway applications, acid resistance applications, bearings for bearings covered for passenger cars, general service bearings for moderate pressures, rod wear material Bushings, wedge wear material, shoe wear material, pump impellers for acid mine water, pump bodies for acid mine water, bearings for freight wagons, bearings for coated bearings for
locomotives
MARINO: large bearings for ships.
