A wrought aluminum-nickel-iron-copper alloy exceeding the minimum requirements of ASTM. The material is recommended for heavier-duty applications involving wear and fatigue.

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

AMPCO® 483 alloy will maintain mechanical properties at temperatures up to 315°C 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 705° to 926°F and annealed between 705° and 880°F. 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.
