On September 3-4, 2026, Wall Colmonoy Oklahoma City (Aerobraze OKC) won a multi-year contract with the US Air Force to remanufacture F-16 primary and secondary regenerative heat exchangers, valued at nearly $6 million over five years. The company beat at least two out-of-state bidders and is located adjacent to Tinker Air Force Base, the Department of Defense's largest MRO facility with 27,000 personnel. With over 60 years of experience in military aircraft heat exchanger manufacturing, overhaul, and remanufacturing, Wall Colmonoy developed F-16 heat exchanger overhaul and core replacement procedures for the USAF in the 1990s, with high-temperature furnace brazing as a core process. The company is also a long-established manufacturer of Colmonoy nickel-based hardfacing alloy powders and brazing materials. The 'repair instead of replace' model continues to expand in US military fleet maintenance. Value for powder buyers: 1) The military maintenance base for brazing alloy and hardfacing powders continues to grow; these Air Force remanufacturing contracts signal sustained long-term demand for brazing and hardfacing powders. 2) As the 'repair instead of replace' model gains traction, military aircraft MRO will see increased consumption of high-temperature furnace brazing materials. 3) Growing use of hardfacing alloy powders in aerospace maintenance applications opens up a niche military maintenance market for powder producers.
