Materials Expertise
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 |
