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.
BS1400 AB2 alloy is the most commonly used Cast version of 10/5/5/ Aluminium Bronze and is usually compared with CA104 when a wrought alternative is required. AB2 is widely used for marine applications having superior corrosion resistance to marine conditions, high strength, good wear & erosion resistance and excellent toughness to bear shock loading. AB2 comes out as a preferred choice when running against stainless steels or any other grades of Nickel Aluminium Bronze alloy.

AEPL produces C95500, C95410, C95800, CB-333G, CB-334G, CuAl10Fe5Ni5, C63000, Nickel Aluminium Bronze 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.
