Inconel 600 is a nickel-chromium alloy known for its excellent resistance to oxidation and corrosion at high temperatures. The alloy has good mechanical properties and is resistant to corrosion in various environments.
Tesla states that the main battery pack contactors in its Model S use Inconel instead of steel. This allows them to remain resilient under the high temperatures of strong currents. SpaceX uses Inconel in the Merlin engine manifolds that power the Falcon 9 launch vehicle. Inconel is commonly used in applications that require heat and corrosion resistance.
What is inconel 600 material?
Inconel 600 primarily consists of nickel (minimum 72%), substantial amounts of chromium (14-17%), iron (6-10%), and small quantities of other elements such as carbon, manganese, silicon, and copper.
