Silicon Brasses are part of the subgroup of high strength brasses. Silicon Brass castings exhibit moderate strength and very good aqueous and atmospheric corrosion resistance. The conductivity of the silicon brasses is much less than that of unalloyed copper. They are also known as Silicon Red Brasses.
C87850 is widely known as Eco Brass and is an environmental friendly alternative for applications requiring high strength and corrosion cracking resistance while maintaining good machinability. It is known for its excellent castability and equivalent to stainless steel. This alloy is an ideal solution for Water supply devices, faucets, taps and automotive parts.

AEPL produces CuZn37Mn3AlPb2Si, CW-713R, C69100, C69400, C69700, C87400, C87500, C87600, C87800, Silicon Brass Ingots 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.
