DESCRIPTION

AMPCO® 15 is a wrought aluminum-iron-copper alloy recommended for medium-duty applications involving wear and fatigue, especially where higher ductility is required for cold working.

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

AMPCO® 15 alloy will maintain its mechanical properties at temperatures up to 315°C. It has a machinability rating of 50%. The alloy provides excellent corrosion resistance to sea water and nonoxidizing mineral acids. It can be welded with gas shielded and shielded metal-arc processes. Brazing, soldering and oxyfuel gas welding are not recommended.

Hot and cold formability is good with a forgeability rating of 75%. AMPCO® 15 alloy can be hot worked at temperatures from 760° to 900°C and annealed between 595° and 650°C.

The consistent superiority of AMPCO® 15 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.
