Aluminium Bronzes comes from a family of copper based alloys which offers a combination of chemical and mechanical properties unmatched by any other alloys. This combination makes them today's one of the most important engineering materials for highly stressed components in corossive environments. Unlike Nickel Aluminium Bronzes, the Nickel percentage in this alloys is usually less which is offset by addition of Copper and other Alloys.
IS:3091 is the Indian Standard of Aluminium Bronze Ingots and castings used for Overhead Equipment fittings in Railway Electric Tractions.
| ELEMENT | Copper | Aluminium | Iron | Manganese |
|---|---|---|---|---|
| Min (%) | Balance | 9.00 | 4.00 | 0.10 |
| Max (%) | 11.00 | 5.00 | 0.50 |
Note: Ni includes Co; Cu+ named elements >= 99.5%; Unless otherwise noted, single values represent maximums.
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.
