Ensinger PEI
Ampco Metal AMPCO® 483 Aluminum-Nickel Bronze, Extruded Rod, 25.4 - 50.8 mm.
Categories: Metal; Nonferrous Metal; Copper Alloy; Bronze

Material Notes: Ampco 483 alloy will maintain mechanical properties at temperatures up to 315ºC and has a machinability rating of 20%. The alloy provides excellent corrosion resistance to sea water and non-oxidizing mineral acids. Can be welded with both the gas-shielded and shielded metal-arc processes. Brazing, soldering and oxyfuel gas welding are not recommended. Ampco 483 alloy can be hot worked at temperatures from 705º to 926ºF and annealed between 705º and 880ºF. The alloy has a forgeability rating of 75%. The consistent superiority of Ampco 483 alloy over commercial bronze is due, in large part, to the unique distribution of alloy microstructure, often referred to as the Ampco-Phase. Only Ampco alloys offer this metallurgical advantage.

Applications: Uses include: cams; bushings; bearing retainer cages; valve stems and guides; sleeve bearings.
