Phosphor Bronzes are part of the Tin Bronze family which are popular for their strength and hardness gained by the addition of phosphorous 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.
PB1 is a copper based alloy with 10-12% Tin content. The high content of tin imparts a very good corrosion resistance in marine environments specially to seawater and brine, making it suitable for pump and valve components. PB1 is generally suitable for machining but is slightly tougher than leaded bronze.

AEPL produces PB-2, 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.
