Same energy as a YouTube comment I read on a War Thunder video that said, "The thermite mixture is a combination of finely powdered aluminum and iron(III) oxide (also called ferric oxide) in a mass ratio of 1:3 respectively, a 5-7.5cm length of fireworks sparkler."
Alternatively, magnesium shavings can be used in place of a sparkler for ignition. You can also reduce the ignition temperature by adding powdered magnesium on top or mixing it in up to 10%.
