Nickel Aluminium Bronzes comes from a family of Copper Alloys where Aluminium is the principal alloying element. They are valued for their higher strength and corrosion resistance as compared to other Bronze Alloys. It also exhibits good resistance to dealumnification when heat treated.
CuAl10Fe5Ni5 Alloy can tolerate high loads but as this is a cast alloy and of low integrity, is generally restricted to slow moving parts with good lubrication. This alloy has good wearing qualities and is suitable for elevated temperature use.

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.
