Leaded Tin Bronze or High Leaded Tin Bronze are less expensive when compared to other bearing alloys. Primary function of this alloy is to improve machinability. Leaded Bronzes are well known for their resistance towards Corrosion and abrasion. The higher lead content allows the alloy to retain favourable thermal conductivity and good lubricity.
C93200 is considered as the general purpose bearing alloy in Leaded Tin Bronze family. It has excellent machining properties, improved hardness, strength and wear resistance with excellent antifriction qualities. C93200 Alloy is not subject to dezincification. C93200 is considered as the workhorse alloy in this family finding its applications in Bushing, Bearings and Automotive fittings.

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.
