PHOSPHOR BRONZES : CASTINGS TO BS SPECIFICATIONS

Phosphor Bronze castings

Phosphor Bronze castings are available in either Leaded Bronzes or Leaded Phosphor Bronze. The following Bronzes LB1, LB2, LB3, LB4, LB5 and LPB1 are most often used as bearings for their wear-resisting properties but are applied where loading is less severe and lubrication and alignment less satisfactory. The lead is present as isolated particles in the structure and thus acts as its own lubricant if the applied lubrication breaks down. Phosphor Bronze high lead alloys LB1, LB4 and LB5 have particular advantages in this respect but because of their low strength and high plasticity they are only suitable for light loading and require rigid backing. LPB1, LB2 and LB3 have somewhat higher strength and rigidity and are thus excellent general purpose bearing alloys.

Phosphor Bronzes

The following Phosphor Bronzes PB1, PB2, PB3, PB4 & CT1 are predominantly used for their wear resistance and bearing properties. Bronzes PB1 and PB2 are preferred in the form of heavy duty gears, worm-wheels and bearings for the more critical applications where high working loads, high speeds, impact loading and pounding coupled with adequate lubrication and good alignment are found. Phosphor Bronze PB4 is adequate for the less critical applications. PB3 and, more particularly the phosphorus-free CT1 are used for corrosion-resisting shaped castings operating in acid conditions.
