Inconel vs Titanium: Differences and Applications
The versatility of materials helps choose them for components of varied types based on the characteristics they possess. Inconel and titanium are two elements that are used very commonly.
Each material has its own properties and applications. If you want to learn about comparing Inconel vs titanium, the guide below can help you compare Inconel and titanium.
Qu'est-ce que l'Inconel ?
Inconel is a superalloy with multiple grades and variants. Its alloys have iron, chromium, nickel, cobalt, manganese, and tantalum.
Inconel is a high-performing material that offers excellent resistance to corrosion and high performance when subjected to high temperatures.
Qu'est-ce que le titane ?
Titane is also a metal that offers excellent corrosion resistance, high strength, and lightweight characteristics. Titanium is used in many industries and is even suitable for use in environments subjected to high stress and high temperature.
Difference Between Inconel and Titanium
A detailed comparison between Inconel and titanium is discussed below.
Inconel vs. Titanium: Color
Inconel is silver or metallic grey in color. In contrast, titanium is silver, but due to the oxidation of this material, it can have multiple colors ranging between blue and purple.
Inconel vs. Titanium: Density
Inconel is a heavy material, whereas titanium is a lightweight material, which makes it suitable for applications like aerospace.
Inconel vs. Titanium: Hardness
Inconel offers high hardness compared to titanium. Though titanium is soft, it is not as strong as Inconel, and to enhance its strength, some alloying elements are required.
Inconel vs. Titanium: Strength
Inconel is a high strength material and stays intact when exposed to extreme temperature and heat. However, titanium lacks strength compared to Inconel.
Inconel vs. Titanium: Melting Point
Inconel offers a high melting point, which makes it suitable for environments that have high temperatures. Compared to Inconel, the melting point of titanium is lower, which means it cannot withstand extreme temperatures.
Inconel vs. Titanium: Heat-conducting Property
The heat conductance in Inconel is much less than that of titanium. Hence, Inconel is not suitable for heat-transferring applications.
Inconel vs. Titanium: Electrical Conductivity
Inconel and titanium are both poor conductors of electricity; however, titanium is a slightly better conductor than inconel.
Inconel vs. Titanium: Corrosion Resistance
Corrosion resistance offered by inconel and titanium is excellent. Inconel resists corrosion in high-temperature and corrosive environments. Meanwhile, titanium resists corrosion in marine environments.
Inconel vs. Titanium: Magnetic
Inconel possesses magnetism and hence is suitable for applications that need it. Whereas, titanium is a nonmagnetic material and is opted for applications that avoid magnetism.
Inconel vs. Titanium: Weldability
The hardness of the Inconel makes welding challenging. Titanium is easy to weld but requires care, as a temperature that is too high may cause a lack of precision.
Inconel vs. Titanium: Cost
Inconel consists of many alloys, which makes it expensive. Titanium is cheaper than Inconel but relatively more expensive than other metals.
Inconel vs. Titanium: Recyclability
Inconel and titanium are both recyclable. However, the process of recycling inconel is complex as it involves a lot of alloys.
