Based on the aircraft type, the market is segmented into commercial aircraft, regional aircraft, helicopter, military aircraft, and general aviation. Despite taking a nosedive in 2020, commercial aircraft is expected to remain the largest and fastest-growing segment of the market during the forecast period. The return to service of the B737Max, the entry of new programs (C919, B777x, and MC-21), and the expected recovery in the production rates of the A320 and B737 programs are likely to fuel the segment’s growth.

Based on the application type, the market is segmented into metal airframe, engine, landing gear, and others. Among these application types, engine is expected to remain the most dominant application in the market during the forecast period. Some of the major milled engine parts are turbine blisks, turbine blades, fuel nozzles, exhaust ducts and cones, impellers, combustion casings, and fan discs. Engine is also expected to witness the fastest growth in the years to come, mainly driven by a handful of engines, such as LEAP, GE9X, GEnx, PW F135, PW1000G, and Rolls-Royce Trent XWB and 7000.
Based on the material type, the market is segmented into aluminum, stainless steel, titanium, and other metals and alloys. Among these material types, aluminum is expected to remain the most dominant material type in the market during the forecast period, whereas titanium is likely to witness the fastest growth during the same period. Key factors for aluminum’s dominance are its excellent track record of over eight decades, lower density, anti-corrosive properties, high malleability, and ductility, and being more economical than its competitive materials, such as titanium. On the other hand, titanium is gaining preference in the market owing to its various benefits, such as high strength-to-weight ratio, high corrosion and heat resistance, and higher compatibility with composite materials. The market for titanium material is majorly propelled through its increased penetration in next-generation aircraft programs, such as the B787 and A350XWB.
Based on the end-user type, the market is segmented into OE and aftermarket. OE is expected to remain the most dominant segment of the market during the forecast period, whereas aftermarket is likely to be the fastest-growing end-user type during the same period. Commercial aircraft (which include narrow-body and wide-body aircraft) account for the majority of the OE sales for aircraft milled parts.
In terms of regions, North America is expected to remain the largest market for aircraft milled parts during the forecast period, driven by the presence of several aircraft OEMs such as Boeing, Airbus, Lockheed Martin, Bombardier Inc., and Gulfstream Aerospace, as well as the presence of several leading tier players and milled parts manufacturers in the region. The USA is likely to remain the leading market, both in, North America and globally, during the forecast period.

On the other hand, key economies, such as India and China, in the region are incessantly increasing their defense budgets with the purpose to acquire the latest military aircraft to solidify their defense capabilities. Implementation of offset policies by the major economies, including India, along with vigorous development of indigenous military aircraft, such as Tejas and J20, further substantiate the demand for milled parts in the region. While China accounted for more than two-fifths of the Asia-Pacific market in 2022, India is likely to be the new growth engine of the regional market in the coming five years.
