This bronze contains a 27 — 63% lead. But the lead is poorly soluble in molten copper. Therefore, after hardening, the alloy acquires a grainy structure. This ensures excellent frictional qualities necessary for the manufacture of bearings, working under high pressure and at high speeds. The conductivity of this material is 4 times higher than tin bronze.
The alloy has a high tendency to gravitational segregation. This requires the use of special measures during casting of the dispersion, accelerated cooling
Lead bronze can be soldered by solders fluxes, which are used for soldering tin bronzes. The soldering should be flucuate more carefully as formed on the surface of the oxides of lead prevent the wicking of solder into the gap.
High impact strength, can withstand lead alloy alternating and shock loads. Lead bronze is used as antifriction alloy for casting on the steel belt, which then produced half of the bearing. She also poured in a steel sleeve. Lead bronze with 60% PB contains 2.25% and 2.7% Ni, it improves the strength and prevents liquation of lead and copper.
