Aerospace Industry
National Bronze & Metals, Inc. (NBM) has brought together a range of copper alloys, specifically for aerospace applications so as to provide you with one source to turn to for your ongoing requirements.
This family of copper alloys is used for a wide variety of applications, such as bearings and bushings in landing gears & cargo doors, wheel and brake components, wing and tail actuators, hydraulic pump components, pylons and many other high demanding applications where heavy loads, corrosion, and abrasion are issues of concern. You will find that we have the right copper alloys that you and the entire aerospace industry demands ready for immediate shipment to anywhere in the United States or across the world.
C17200 (AMS 4533, 4534, 4535, 4650, 4651, QQ-C-530)
Beryllium Copper
Available in solid & hollow bars, and plates
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). Get More Information.
C63000 (AMS 4640)
Nickel Aluminum Bronze
Available in solid bars and plates
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. Get More Information.
C63020 (AMS 4590)
Nickel Aluminum Bronze
Available in solid bars
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). Get More Information.
C64200 (AMS 4631, 4634)
Silicon Aluminum Bronze
Available in solid bars
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. Get More Information.
C65620 (AMS 4616)
Silicon Bronze
Available in solid bars
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! Get More Information.
C67300 (SAE J463, J461)
Manganese Bronze
Available in solid & hollow bars
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. Get More Information.
C86300 (ASTM B-505, B-271, AMS 4862)
Manganese Bronze
Available in solid & hollow bars
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. Get More Information.
C93700 (ASTM B-505, B271, AMS 4842)
High Leaded Tin Bronze "80-10-10"
Available in solid & hollow bars
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%! Get More Information.
C95400 (ASTM B-505, B-271, AMS 4871, 4873)
Aluminum Bronze "9C"
Available in solid & hollow bars and wear plates
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. Get More Information.
C95510 (AMS 4880) Continuous & Centrifugal Cast
Nickel Aluminum Bronze
Available in solid & hollow bars
Get More Information.
C95520 (AMS 4881) Centrifugal Cast
Nickel Aluminum Bronze
Available in solid & hollow bars
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.
