Phosphor Bronzes are part of the Tin Bronze family which are popular for their strength and hardness gained by the addition of phosphorus rather than the more expensive nickel. These alloys are known for their superb spring qualities, high fatigue resistance, excellent formability and solderability and high corrosion resistance. It also offers a good resistance to shock loading.
PB2 is a phosphor bronze with Tin content higher than PB1 making it an ideal material for bearings having medium to high loads and speeds, and has good resistance to impact loading or pounding. It has good machining properties, high strength, good corrosion resistance to brine and seawater, making it suitable for making valve and pump components.

Note: Ni includes Co; Cu+ named elements >= 99.5%; Unless otherwise noted, single values represent maximums.
AEPL produces PB-1, C54400, Phosphor Bronze alloy in the form of Certified Ingots weighing from 8 to 10 Kgs each.
AEPL has implemented a quality system for Copper Based Alloys where all processes are monitored from start to finish i.e. from procurement of raw material, their combination, manufacturing processes, measurement and chemical analysis. We maintain our own laboratory with calibrated equipments to ensure delivery of certified ingots as per International Standards and satisfy clients' requirements. The equipment includes Optical Emission Spectrometer which uses arc and spark excitation technology. Samples of test reports are available upon request.
AEPL manufactures and supplies Copper Alloys products to Domestic as well as International Markets. Located at a single site, our smaller foundries are equipped to use in-house certified ingots and create complex shapes of Copper alloy castings and turn them into finished components using Drilling, Grinding and CNC turning centres.
