From what I've seen, there isn't one fixed thickness that's considered "standard" for Inconel 600 foil. The right choice mostly depends on where it's going to be used. In many industrial applications, the thickness usually falls somewhere between 0.02 mm and 0.20 mm. Foils at the thinner end are commonly used for precision components, thermal insulation, electronics, heat shields, and other applications where flexibility and low weight matter. Thicker foils are generally preferred when the part needs more strength, better durability, or has to go through forming and fabrication processes.
A project I was involved with used 0.05 mm foil because it offered a good balance between flexibility and high-temperature performance. In another case, around 0.10 mm was selected since the component had to withstand more handling during manufacturing. That experience made it clear that the operating conditions play a much bigger role than simply choosing the most common thickness.
One thing I've noticed is that people sometimes focus only on the material grade and forget that thickness is just as important. Even if Inconel 600 has excellent resistance to heat and oxidation, selecting the wrong foil thickness can affect forming, welding, durability, and overall performance. A foil that's too thin may get damaged during fabrication, while one that's too thick can make forming more difficult and increase material costs.
It also helps to consider factors like operating temperature, corrosion exposure, mechanical stress, and the manufacturing process before making a decision. Another practical point is that suppliers don't always stock every thickness, especially the very thin or uncommon gauges, so it's worth checking availability early in the project.
Overall, I think it's best to choose the thickness based on the actual application rather than following a general recommendation. A quick discussion with the supplier or design engineer can often prevent costly mistakes later and help ensure the foil performs as expected throughout its service life.
