This copper alloy can have the
highest mechanical properties
of all copper alloys. This alloy
also has excellent bearing
qualities with extremely high
compressive strength for high
loading applications. It also has
excellent abrasion and corrosion
resistant properties, plus
outstanding cryogenic
characteristics (for space
applications).
|
A high strength, tough nickel
aluminum bronze used where
high mechanical properties are
required. This alloy is a heat
treatable aluminum bronze
containing 5% nickel, that provides
excellent bearing properties
with good corrosion resistance.
It is used extensively for aircraft
landing gear bushings, bearings,
and other military and aircraft
components.
|
A special heat treatment
process improves the
mechanical properties beyond
the range of commercial
aluminum bronzes. This alloy
is an extra high strength
version of nickel aluminum
bronze. It is used where parts
require extra high strength and
hardness with some ductility and
toughness. Typical applications
include military aircraft bushings
involving heavy loads, abrasion
and high deformation. The extra
high strength characteristics
provide extreme wear resistance
for extreme loads, abrasive
wear, and high impact landings
(such as aircraft carrier landings).

This silicon aluminum bronze
combines the self lubricity of
the silicon with the higher
mechanical properties of
aluminum bronze and is
sometimes used in place of
C63000 where specifications
permit a lower strength material
offset by its lubricity. Typical
applications involve valve stems,
gears, marine and pole line hardware,
wing pylons, bolts, nuts, bushings and
valve body components.
|
A special high strength silicon
bronze; the additional iron
content provides added strength
in conjunction with the self lubricity
of the silicon for excellent bearing
and load properties. Easily machined
into ball bearing cage assemblies!
|
This is a high strength manganese
bronze with typically good
bearing and self lubricity
properties. This alloy
maintains high impact
resistance with good machinability
making it well suited for clutch
bearings, shaft bushings, sleeve
bearings, thrust bearings, pump
parts, drive shafts, bearing pins,
wear plates, gears and cams.
Resists squashing out under high
loads and extreme wear
applications.

This cast manganese bronze is
typically supplied in continuous
cast or centrifugally cast bars
and tubes for high load gear
and bearing applications. This
material achieves over 110 ksi
tensile strength and an elongation
of 14% minimum. It is excellent
in applications requiring high
strength metal to metal wear.
|
This is a high leaded tin bronze
used for high speed and heavy
pressure applications where
corrosion resistance is necessary.
The increased lead content provides
added self lubricity within the family
of tin bronzes. Excellent machinability
at 80%!
|
This is the most popular aluminum
bronze and is used in a lot of different
industrial applications. This extra tough
bearing material is used for heavy loads
with good resistance to impact and
corrosion. Aluminum bronze has a lot of
good properties and is the most readily
available high strength bearing material.

These are the most popular
landing gear bushing materials
specified today along with C63000
material. These continuous /
centrifugal cast alloys are heat
treated alloys and exhibit high
mechanical strengths which meet
the properties of C63000
(AMS 4640). In many cases
C95510 (AMS 4880) can be
substituted for C63000 with the
advantage of the material being
available in tube form which provides
economic cost savings for you,
the customer.

This is a European high strength
bearing bronze which is utilized
by Airbus for landing gear
components.

|
This oil impregnated bronze is
one of the finest powder metal
bearings on the market. The
sintering process provides
superior strength, reduced
coefficient of friction, and
uniform oil coating of the
mating shaft during operation.
