C95500 Aluminum Bronze is a non-lead “GREEN” Alloy
Nickel Aluminum Bronze
CDA 955
9D
ASTM B271
Aluminum bronze is a very hard, strong, abrasion resistant bronze whose physical properties remain
good at elevated temperatures – compressive strength at 500°F is the same as that of tin bronzes at
room temperature. Good applications include heavy earth moving equipment, roll neck bearings, and
machine tool bearings.
Solid and cored bars are stocked in 13" increments and 144" lengths, and are available in other
lengths and non-standard sizes. Consider bars for use when you need special bearings, bearings for
prototypes, or for emergency repairs.
Centrifugal cast large diameter cored bars are also available in 13" lengths as well as made to order
sizes and lengths.
C95500 is available in either as cast condition or heat-treated.

C95500 Aluminum bronze is used for low speed, and very high load bearing applications. The addition
of nickel increases the physical properties and corrosion resistance compared to C95400. C95500 requires
hardened steel shafts and constant lubrication of grease, graphite or molybdenum-disulfide.
