Description
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 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.
