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.
C91700 comes with an added amount of Nickel for which it is known as Nickel Tin Bronze or Nickel Gear Bronze. The addition of Nickel to the standard 12% Tin bronze gives additional wear resistance and improved corrosion resistance in brackish water systems.

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.
