Leaded Commercial Bronze Hollow Bar Rod / C19140 Low Leaded Commercial Bronze Hollow Bar Rod
C19140 Low Leaded Commercial Bronze Hollow Bar Rods are precision-engineered copper alloy products offering excellent machinability, good corrosion resistance, and reliable mechanical strength. They are ideal for bushings, bearings, sleeves, valve components, fittings, and precision engineering applications requiring smooth machining, dimensional accuracy, and long-lasting performance.

C19140 is unique precipitation hardening alloys containing copper, lead, nickel and phosphorus. The nickel and phosphorus in the alloy combine to form nickel phosphate, which dissolves in the copper on heating to a suitable temperature, and can be retained by quenching. Subsequent aging will precipitate the nickel phosphate from solid solution in a highly dispersed manner thereby creating a remarkable hardening and strengthening effect with excellent stress relaxation properties. Subsequent cold working increases the strength still further.
