Phosphor Bronzes are part of the Tin Bronze family which are popular for their strength and hardness gained by the addtion of phosphorus rather than the more expensive nickel. These alloys are known for their superb spring qualities, high fatigue resistance, excellent formability and solderability and high corrosion resistance. It also offers a good resistance to shock loading.
C-54400 is a high graded leaded tin phosphor bronze with a unique composition and often called as the "finest bearing alloy on the market". It is a multi alloy bronze, popular with machinists due to its outstanding properties like extreme ease of machining, high strength, toughness, fine grain strcuture and low coefficient friction. The alloy is also resistant to fatigue, wear and chemical corrosion.
| ELEMENT | Copper | Iron | Zinc | Lead | Tin | Phosphorus |
|---|---|---|---|---|---|---|
| Min (%) | Balance | - | 1.50 | 3.00 | 3.50 | 0.01 |
| Max (%) | 0.10 | 4.50 | 4.00 | 4.50 | 0.50 |
Note: Ni includes Co; Cu+ named elements >= 99.5%; Unless otherwise noted, single values represent maximums.
AEPL produces PB-1, PB-2, Phosphor 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.
