Description
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 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. Can be welded with gasshielded 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.
