Material trends in landing gear
Where do we go from here?
Materials trends for landing gear.
Titanium 6-4 (Ti 6Al 4V) is the workhorse of the industry and still accounts for nearly 60% of the production volume. However, new materials have reached the market in recent years. The introduction of AerMet100 and AF1410 has made inroads in the steel section and replaced some of the 300M and 4340 materials used on landing gear, while the appearance of titanium alloys such as Ti 10-2-3 (Ti 10V 2Fe 2Al) and most notably Ti 5-5-5-3 (Ti 5 Va 5Mo 5Al 3Cr) recently has transformed the landing gear materials application especially on the new generations of wide-body aircraft. With these materials come new machining challenges and requirements for optimised tooling.
