AMS 4880 is one of the most popular landing gear bushing materials specified today
along with C63000 material. This continuous / centrifugal cast alloy is heat
treated and exhibits high mechanical strength which meets the properties of
C63000 (AMS 4640). In many cases C95510 (AMS 4880) can be substituted for
C63000 with the advantage of this material being available in tube form, which
provides economic cost savings for you, the customer.
