Onamac has experience machining a wide variety of metals with aerospace applications. Depending on the design and end purpose of the required part, there are several alloys and machining methods that can be used to arrive at the required confluence of strength, flexibility, weight, durability, and economics. The influence of these factors changes for each part of the aircraft.

Metals Machined	Characteristics	Example Aerospace Application
Aluminum	Soft metal, light & durable	Wing leading edge, landing gear components & support fittings, and floorbeams
Aluminum-Nickel-Bronze	Soft metal, highly resistant to corrosion	Bearings, landing gear components
Inconel	Hard metal, used in high-temperature applications	Engine parts
Stainless Steel (13-8, 15-5) & Steel Alloys (300M, 4330, 4340)	Hard metal, highly resistant to corrosion	Structural components
Titanium	Hard metal, extremely high strength-to-weight ratio	Engine & frame components
