When choosing materials for aerospace components, you can consider things like: Strength-to-weight ratio Ultimate strength Low-velocity impact strength Fatigue strength Resisances to creep, crack propagation, corrosion, and exfoliation corrosion Weight Lifespan and reliability Fatigue resistance Some materials used in the aerospace industry include: Aluminum alloys: Used for airframes and skin, aluminum is lightweight and technically advanced. Titanium alloys: Have high specific properties, a good fatigue strength/tensile strength ratio, and good resistance to corrosion. Titanium is also corrosion resistant and can withstand high pressure, radiation, and corrosion. High-strength steels: Known for having surface hardness and high strength, but they are heavier than other materials. Composites: Made by combining two or more materials to create a material with unique properties. Composite materials are lightweight, strong, and durable, but they cannot survive temperatures above 200 degrees Celsius. Carbon fiber: Also called as graphite fiber, carbon fiber is made up of extremely thin fibers about 0.0002 – 0.0004” in diameter. It has excellent tensile strength, heat resistance, and chemical resistance. Stainless steel: Used in superalloys, stainless steel is corrosion resistant. Magnesium: Lightweight, but not strong enough to be used on its own, magnesium is often combined with other metals, such as manganese, zinc, and aluminum. Show less
