The MiG-29 Fulcrum is one of the more modern front-line fighters in the Iranian Air Force. Its structure is primarily aluminum alloy, with titanium alloy reinforcement in critical frames and aluminum–lithium alloy skins on the wings. A small percentage of composites is used in the tail surfaces, ailerons, flaps, rudder, and the dielectric nose radome. CNC machining is most important for wing-beam repair parts, titanium reinforcement frames, control-surface brackets, radome mounting rings, and landing-gear interfaces. Technical references describe MiG-29 structures as mainly aluminum-based, with titanium used in selected reinforced frames and aluminum–lithium used in wing skins.

Definition
The MiG-29 is a lightweight twin-engine air-superiority fighter originally developed for high agility and short-field operations. In the context of recent defense aerospace tensions, it is discussed as part of Iran's limited modern fighter force. For CNC suppliers, the MiG-29 represents medium-complexity legacy-fighter repair, where aluminum dominates but titanium and composites still require specialized machining.
How It Works
The MiG-29 is designed for rapid acceleration, high maneuverability, and short-field basing.
Aluminum alloys form the primary fuselage and wing structure.
Titanium alloys reinforce selected bulkheads and high-stress frames.
Aluminum–lithium alloys reduce weight in wing skins and leading-edge structures.
Carbon-fiber or glass-fiber composites are used in the vertical tail, rudder, ailerons, flaps, and other control surfaces.
Dielectric composites form the nose radome to allow radar signals to pass through.
CNC machining is required because even an aluminum-dominant fighter needs precision brackets, hinge fittings, repair frames, and composite-to-metal interface parts.
