C17200 (AMS 4533, 4534, 4535, 4650, 4651, QQ-C-530) Beryllium Copper Available in solid & hollow bars, and plates	C63000 (AMS 4640) Nickel Aluminum Bronze Available in solid bars and plates	C63020 (AMS 4590) Nickel Aluminum Bronze Available in solid bars
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). Download PDF Spec sheet for C17200.	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. Download PDF Spec sheet for C63000.	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).

C64200 (AMS 4631, 4634) Silicon Aluminum Bronze Available in solid bars	C65620 (AMS 4616) Silicon Bronze Available in solid bars	C67300 (SAE J463, J461) Manganese Bronze Available in solid & hollow 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. Download PDF Spec sheet for C64200.	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! Download PDF Spec sheet for C65620.	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. Download PDF Spec sheet for C67300.
C86300 (ASTM B-505, B-271, AMS 4862) Manganese Bronze Available in solid & hollow bars	C93700 (ASTM B-505, B271, AMS 4842) High Leaded Tin Bronze "80-10-10" Available in solid & hollow bars	C95400 (ASTM B-505, B-271, AMS 4871, 4873) Aluminum Bronze "9C" Available in solid & hollow bars and wear plates
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. Download PDF Spec sheet for C86300.	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. Download PDF Spec sheet for C95400.
C95510 (AMS 4880) Continuous & Centrifugal Cast Nickel Aluminum Bronze Available in solid & hollow bars	C95520 (AMS 4881) Centrifugal Cast Nickel Aluminum Bronze Available in solid & hollow bars	UZ19AL6 Aircraft Bronze Available in solid & hollow bars
Download PDF Spec sheet for C95510.	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 formwhich provides economic cost savings for you, the customer. Download PDF Spec sheet for C95520.	This is a European high strength bearing bronze which is utilized by Airbus for landing gear components.
SAE 841 (ASTM B-438, B-4831) Sintered Bronze Available in solid & hollow bars
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. Material is available in solid, cored, and rectangular bars from stock! Download PDF Spec sheet for SAE841.
