30*40*1.2 Aluminum alloy rail weight

3888 grams. According to the query new energy network shows that the density of aluminum alloy 2.7 grams per cubic centimeter, 30 * 40 * 1.2 aluminum alloy rail volume is: 30 times 40 times 1.2 is equal to 1440 square centimeters, multiply the volume by the density that is 1440 times 2.7 is equal to 3888 grams. Therefore, the weight of 0*40*1.2 aluminum alloy rail is 3888 grams. Aluminum alloy to aluminum-based alloy with a certain amount of other alloying elements, is one of the light metal materials.
