No, aluminum foil will not burn in the oven. Tin foil is made of aluminum, with a very high melting point - 1200 degrees Celsius- twice as much as the average oven temperature. That means that aluminum foil won't start to melt and catch fire until it reaches incredibly high temperatures. So, if you're using aluminum foil in the oven, you don't need to worry about it catching fire. However, aluminum foil can still conduct heat, so it's essential to use it carefully to avoid causing any accidents.
