What Ferrotherm Corporation does

Ferrotherm Corporation (DBA Ferrotherm LLC) is a privately held precision aerospace components manufacturer headquartered in a 78,000 square foot facility in Cleveland, Ohio. Founded in the late 1940s and operating continuously since, the company specializes in newly manufactured honeycomb brazed gas turbine engine components - including honeycomb seals and shrouds, rings and segments, duct segments, blade tracks, and vane assemblies - manufactured to tight aerospace tolerances. The company holds dual ISO 9001 and AS9100 certifications and operates an integrated in-house manufacturing stack spanning precision turning (capable of 3" to 70" diameter components), precision milling, grinding, welding, and electro discharge machining.

The company's commercial model is a direct Tier 1/Tier 2 aerospace supplier selling custom-manufactured hardware and reconditioning services to a named set of enterprise OEMs and government customers. Documented customers include GE Aviation, Rolls-Royce, Pratt & Whitney, Lockheed Martin, Boeing, Sikorsky, Gulfstream, ITP, Techspace Aero, and Samsung on the commercial side, and the U.S. military and NATO militaries on the defense side, with explicit program exposure to the F-35 Lightning II, B-52 Stratofortress Re-Engine Program, UH-60 Black Hawk Re-Engine Program, and Gulfstream G650. Revenue is generated through quote-based enterprise sales (new component manufacturing) and a component repair and reconditioning service line executed per customer technical orders to extend engine life.

The company is privately held, independently owned, and reports 51-100 employees. Revenue, ownership structure, and any investor backing are not publicly disclosed, and no funding rounds, M&A activity, or leadership changes are documented in the available source material. Marketing is limited to a corporate website with direct-contact sales engagement; the company does not maintain a presence on major social platforms and lists openings via Indeed rather than a built-out careers portal.
