PB1 Phosphor Bronze – Solid/Hollow Round

PB1 Phosphur bronze is a high strength allow suitable for machining, with common applications in high pressure contact working loads/speeds, it’s characteristics promote its use in seawater applications for pump and valve components, additionally PB1 Bronze is resistant to impact loading.  PB1 is generally continuously cast or centrifugal cast (both of these manufacturing methods assure porosity free finishes)

Assure when using this material good lubrication is provided to the bearing surface.
