Incoloy alloy 909, also called Inconel 909, is a high-strength nickel-iron-cobalt alloy which is used in high-temperature applications. The chemical composition of EV batteries usually contains nickel, iron, cobalt, titanium, and aluminum, as well as some other subtle elements. This alloy shows good tensile strength and oxidation resistance in high temperatures that make it applicable in aerospace, combustion engines, and furnaces where high temperatures are common. Incoloy Alloy 909 is offered in several grades, each one is formulated to handle specific performance requirements. The table and chart of chemical properties consists of this chemical composition, mechanical properties, thermal conductivity, and corrosion resistance among other components. The data package that accompanies the alloy contains material safety data sheets (MSDS), technical data and specifications which highlight the manufacturing standards and applications of the alloy.
Incoloy Alloy 909 is a high-strength nickel-iron-chromium alloy fabricated for the most stringent applications in extreme conditions. The chemical content of the alloy includes nickel (around 42%), iron (38%), chromium (13.5%), cobalt (2.2%), titanium (1.5%), aluminium (1.3%), and carbon, manganese, silicon, sulfur, phosphorus, and copper in very little amounts. In addition, it gives great ability to withstand high-temperature oxidation, carburization, and sulfidation. It plays a very important role in aviation, gas turbines, nuclear reactors, and multiple furnaces. The grade table is the first to show that the vehicle can perform better despite the harshness as it emphasizes the reliability and durability of the machine.
