When we hit 2 stones they produce fire ,it is due to the friction between the surfaces of 2 stones . metel cannot do so is a misconception . Most metals can burn. In fact, it burns very hot, and is very difficult to put out. Metal fires are not a fun thing to deal with.
The reason you rarely see metals burn is because the air can't get inside it. The surface layer reacts with oxygen, forming a barrier so the oxygen can't get to the rest of the metal, so the flame can't continue. If you arrange metal so that air can get inside (like a metal powder dispersed in the air, or very fine steel wool), it will light on fire quite easily, and be very difficult to put out. This is actually a real danger in facilities that produce metal dust, like machine shops. If enough fine metal dust accumulates and gets dispersed in the air, you can have a massive fireball.
