All right everyone, welcome back to Cody’sLab So, today I’m gonna compare iron thermite with copper thermite. I gotta enough here to make 20 grams of each and the particle size should be about the same for both mixtures. I’m using an electrical ignition system to light both at the same time. The copper went up in a blinding flash, and the iron just keeps on burning. Copper has a much lower melting point than iron does, which means more energy is available to continue the reaction, rather then just melting the ingredients. Also copper has a higher density than iron so you have more heat in a smaller space. Hope you all enjoyed, I’ll see you next time.
