How Automotive Manufacturers Use Alloy 718 - and What to Order?
The automotive industry has changed rapidly over the past decade. Today’s vehicles demand materials that can handle extreme temperatures, high pressure, vibration, and long-term fatigue. One material that stands out for these needs is Alloy 718. Known for its strength, corrosion resistance, and heat stability, it has become a popular choice among vehicle and component manufacturers worldwide.
Understanding Alloy 718
Alloy 718 is a nickel-chromium superalloy known for:
- High tensile and yield strength
- Excellent resistance to heat and oxidation
- Superb fatigue and creep resistance
- Good weldability compared to other superalloys
- Stability in temperatures up to 700°C
Because of these properties, Alloy 718 is used in industries where safety, durability, and performance cannot be compromised.
Why the Automotive Industry Chooses Alloy 718?
Modern vehicles, especially high-performance cars, EVs, and turbocharged engines, generate high thermal loads. Standard materials often fail in such conditions, but Alloy 718 maintains strength even under extreme heat and mechanical stress.
Automotive manufacturers choose Alloy 718 for its:
- Ability to handle high-temperature environments
- Resistance to corrosion caused by fuel, oils, and chemicals
- Long operational life with minimal maintenance
- Compatibility with precision machining and forming
- Reliability under continuous vibration and pressure
This makes Alloy 718 not just a material option but a performance solution.
