Aerospace Grade Metals

Aerospace Grade metals, also called Aircraft Grade metals or Aviation Grade metals, are typically used for all major components where the “ASM” aerospace specification metals are required. Airplanes, helicopters and spacecraft need materials with high strength-to-weight ratios and typically high corrosion resistance. We carry a wide range of aerospace metals in various shapes, alloys, and sizes, including but not limited to aerospace sheet metal, bars and tubes.

“When building our rocket engine, we consider materials very carefully based on required function, operating environment, and our engineering analysis of applied loads. Some key areas where Online Metals is able to support us are on our engine’s inner liner, outer jacket, and injector.– Michigan Aeronautical Science Association (MASA)

Generally, aluminum makes up between 80% to 90% of the structural weight of most modern commercial aircraft. What makes aluminum such a great material for aircraft is its high strength-to-weight ratio, corrosion resistance, and ease of fabrication. It is used in aircraft fuselages, wings, and other structural components to reduce weight and improve fuel efficiency.
