A wrought aluminum-iron-copper alloy recommended for medium-duty applications involving wear and fatigue, especially where higher ductility is required for cold working. 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 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. Applications: Uses include: cams; bushings; bearing retainer cages; valve stems and guides; sleeve bearings. |
