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).
AMS 4640 'H' (C63000) Nickel Aluminum BronzeAvailable 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 components.
AMS 4881 'D' Continuous Cast (C95520) Nickel Aluminum BronzeAvailable in solid & hollow 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).
AMS 4616 (C65620) Silicon BronzeAvailable 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 a ball bearing cage assemblies!
AMS 4634 (C64200) Silicon Aluminum BronzeAvailable 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.
C67300 (SAE J463, J461) Manganese BronzeAvailable 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.
AMS 4862 (C86300) Manganese BronzeAvailable in solid & hollow bars
This cast manganese bronze is typically supplied in a 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 for applications requiring high strength metal to metal wear.
AMS 4842 (C93700) 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%!
AMS 4871 (C95400) 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.
AMS 4880 'E' Continuous Cast (C95510) Nickel Aluminum BronzeAvailable 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.
AMS 4590 (C63020) Nickel Aluminum BronzeAvailable in solid & hollow bars
A special heat treatment process improves mechanical properties and strength-weight ratio beyond the range of commercial aluminum bronzes. For applications involving heavy loads, abrasive wear, friction, deformation and high temperatures.
C95500 Nickel Aluminum Bronze '9D'Available in solid bars, tubes, shapes, wear plates and machined parts
C95500 Nickel Aluminum Bronze, also known as 9D, contains nickel similar to other grades of high strength aluminum bronzes, which makes it one of the toughest alloys in the industry. C95500 Nickel Aluminum Bronze also has superior resistance to sea water corrosion, heat resistance, good machinability, and weldability. Other benefits of CDA 955 are exceptional yield, compressive strength, high hardness, and fairly high elongation. This alloy can also be readily used for all lead-free applications.
