Aluminum is a light metal, and its compound is widely distributed in nature, and the amount of aluminum in the crust is second only to oxygen and silicon, ranking third. In all metal varieties, the yield is second only to steel, which is the second largest metal. The density of aluminum is 2.7103 g / cm3, about 1/3 of steel and copper density, and the specific gravity is 2.7. Aluminum has special chemistry, physical characteristics, not only lightweight, texture, but also has good ductility, conductivity, thermal conductivity, heat resistance, and nuclear radiation, is an important foundation raw material for national economic development. Aluminum rods perform non-ferrous metal industry standards (YS / T 67-2012) should be called "aluminum alloy round ingots", is the most important primary product after aluminum spindle and casting, is the main primitive of aluminum profiles, of which The Aluminum rod of the number 6063 is the widest range of breeds in the market.
