Material Selection in Aerospace
The aerospace industry requires high-performance materials that can withstand extreme temperatures and provide sufficient strength. Components must also be long-lasting and fatigue-resistant to maintain consistent reliability.
Another key variable when selecting your materials is weight. Aerospace materials must facilitate fuel efficiency and aerodynamic flight while maintaining high damage and corrosion resistance. They also require greater durability for use in fuselages and other equipment. Otherwise, engine components and other parts may not perform adequately with prolonged exposure to harsh environments.
Wings are a particularly important part of aircraft, requiring superior metal construction with fracture toughness, fatigue resistance, and compressive yield strength.
Material Innovations
Certain innovations in aerospace materials continue to benefit this industry. For example, there has recently been a 20% decrease in the ratio of aluminum construction in aircraft, with other more ideal materials taking aluminum’s place over time. One potential replacement is composite metal foam (CMF), which offers increased durability and toughness with the same lightness. Researchers at North Carolina State University are testing this material for use in aerospace and other applications.
Another promising alternative to aluminum is lightweight carbon fiber reinforced polymers (CFRPs), which allow for the development of visually appealing panels and other interior components. Meanwhile, more materials may use honeycomb structures for improved strength and durability. Engineers are currently exploring other heat-resistant and lightweight options to replace aluminum.
Materials Used for Aircraft Manufacturing
The following are some of the main types of aerospace materials available for various applications:
- Titanium Alloys. Many aerospace components use fatigue-resistant titanium alloys, which have a high tensile strength and fatigue strength ratio. Some alloys can also resist temperatures as high as 400 to 500 C.
- Steels. While their high density limits their use in aircraft construction, some alloys work for small component castings. In this case, their high stiffness, strength, and damage resistance prove highly useful.
- Aluminum Alloys. Although aerospace applications often seek replacements for aluminum, these alloys are still popular because of their flexibility. Applications may use aluminum with other metals to enhance mechanical properties while maintaining lightness in use.
- Fiber-reinforced Composite Materials. Aircraft could also use fiber-reinforced composites that contain fibrous carbon, glass, or other materials in resinous epoxy or plastic matrices. These materials allow for increased chemical and mechanical protection.

Let us explain more about working with this classic alloy so that you can make the right decision for your next project.
What is Inconel?
Inconel is an alloy of nickel that contains chromium and iron. It is referred to as a superalloy due to its exceptional resistance against oxidation, corrosion, and high temperatures. Apart from these properties, Inconel is also known for its incredible tensile strength that allows it to withstand stressful settings, such as high pressures and mechanical loads.
Although Inconel isn’t the only hard material that’s tough to machine, it does present some unique challenges that require specialized tools and techniques.
Typical Uses for Inconel
Inconel is commonly used in rugged environments due to its amazing pressure, temperature, and corrosion-resistant benefits.
Some of its common uses include:
- Propeller blades
- Down-hole equipment
- Nuclear power plant reactors
- Marine equipment
- Propulsion motors
- Firearm sound suppressor baffles
Why is Machining Inconel Difficult?
Inconel’s durability delivers superior performance in strenuous environments but this presents some unique challenges. Inconel’s durability means it’s not an easy alloy to work with.
The main reasons and challenges associated with Inconel machining include the following:
- High work hardening: Inconel has a high hardening rate, making it harder and stronger the longer you work on it. Therefore, this makes it tougher for operators to achieve the desired shape or cut.
- Generates heat easily: While machining Inconel, it generates a lot of heat that can cause thermal damage and dimensional instability.
- Hard to cut: Inconel is one of the hardest materials to cut, which results in tool wear.
- Workpiece deflection: Inconel alloys easily deflect during machining, so there are plenty of dimensional inaccuracies if not adequately controlled.
Inconel Machining Tips to Remember
Understanding Inconel’s properties will help compensate for its limitations. While it presents many challenges, it’s still possible to machine Inconel successfully.
Here are some valuable tips to keep in mind when machining Inconel:
- Check tooling for signs of wear while machining Inconel: Tooling doesn’t last a long time when machining materials as tough as Inconel. Checking on the tooling during the machining process is essential to ensure quality.
- Use coolant: Since Inconel generates heat during machining, using a coolant can prevent thermal damage since the temperature is kept down.
- Opt for ceramic tools: Fast and continuous cuts are crucial to minimize work hardening. With this in mind, specialists highly recommend ceramic tools for uninterrupted cuts.
- Post-machining operations: To achieve a specific project’s needs, post-machining operations are necessary to accomplish consistent quality results.
