Tin Bronze comes from a family of Copper Tin Alloys containing up to 15% Tin. Tin Bronzes are more ductile and stronger in comparison to red brasses and semi red brasses. They have high wear resistance and low friction coefficent against steel. Tin Bronzes are also best known for their Corrosion resistance. Unlike Leaded Tin Bronzes, these alloys contain only minor traces of lead which improves the ductility and tensile strength. High Tin Bronzes are particularly used for certain applications where the less expensive bronzes are not suitable.
This alloy is unleaded hard bronze with good machinability and corrosion resistance, especially to sea water, making it suitable for marine applications where higher strength is required. Bearings manufactured from this alloys are suitable for medium to heavy loadings at low speed.

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.
