It won’t be wrong to say that the automotive industry is a fast-paced industry that’s constantly evolving. We have seen so much technical advancement from the past decade, such as artificial intelligence, cloud computing, etc. That makes our lives easier.  

However, you may or may not be familiar with a secret gem of the automotive industry. Not aware? Well, it is Inconel 718. Inconel 718 is the most used nickel-based alloy in the automotive industry. In recent years the importance of Inconel alloy (also known as superalloy) has increased many folds.  

Why? Because Inconel has creep-rupture characteristics at high temperature and has high strength (tough) and corrosion-resistance properties. In fact, even if you compare stainless steel to nickel alloy (Inconel), the latter will have a high tolerance for extreme heat.  

It doesn’t stop there! There are several other reasons why Inconel alloy is being used in the automotive industry. Keep reading to find out more.  


Top-quality Material

We can’t deny the fact that the US automotive industry is massive. As a matter of fact, it is the world’s second-largest auto market, and that is why there are regulatory frameworks and standards for manufacturers and distributors. One of such standards is to ensure that the whole industry is using top quality materials for manufacturing.  

Nickel-based alloy helps in meeting this requirement as you can rely on them for high performance. According to the experts at, Inconel 718 alloy has various applications when we talk about the production of motor vehicles as well as in the aircraft industry. The reason being the incredible combination of corrosion resistance and strength that assist in the engineering process.  

Not only engines but, it is also required in safety devices, electronic switchgear, spark plug, diesel valves, ignition systems, and much more.  



Less pollution  

Do you know that automotive manufacturers need emission certificates granted by the US environmental protection agency? Moreover, the state of California has its own enforcement program for vehicles sold in California. The purpose behind attaining these certificates is to keep pollution in check.  

So the question is – How do manufacturers control pollution without compromising efficiency? Yes, you are right! It is by using superalloy and, in particular, alloy 718. They are great for enhancing the performance and efficiency of engines, along with creating less pollution. Engineers use alloys in the most heated sections of the engine to avoid corrosion and improve reliability.   


Cost- effectiveness

Even though Inconel alloy is highly used in the automotive industry, it doesn’t cost much. A high level of nickel and chromium present in Inconel 718 provides brilliant resistance to corrosion and works efficiently against the engine’s petrochemicals and high temperature. It helps the manufacturers in delivering high-quality products along with retaining cost.  


The bottom line  

Inconel 718 is already used for various purposes in the automotive industry. It helps create fuel-efficient engines that help enhance the longevity of vehicles and reduce air pollution. Besides, with the characteristics of good fabricability, a high strength-to-weight ratio, and of course, corrosion resistance, we are sure that the demand for this superalloy will rise in the future.
