The authors discovered in first time that the weight of materials or its gravitational force by earth related to its temperature and its ferromagnetism. An experiment was designed to elevate the temperatures of six different materials (Au, Ag, Cu, Fe, Al, Ni) up to 600 ℃ and precisely measured their weights. It is found all the materials weigh about 0.33 ‰～0.82 ‰ less. For example the weight of silver sample weighted by a precision electronic scale in a manner of special design decreases about 0.8 ‰, when its temperature is elevated to 600 ℃. Thus different metals gravitational forces or weights are adjusted with temperature variation.
