Aluminum bar can be used in aviation, aircraft construction, rivet, trailer wheel, the propeller components, metallic building material, forging material, welding material, etc. ALUMINUM BAR supplier Introduction Aluminum (Al) is a kind of light metal, whose compounds are widely distributed in nature. The resources of aluminum in the earth's crust are about 40 to 50 billion tons, ranking the third only after oxygen and silicon.It is the first kind of metal among metal varieties.Aluminum has special chemical and physical characteristics, not only light weight, strong texture, and has good ductility, electrical conductivity, thermal conductivity, heat resistance and nuclear radiation resistance, is an important basic raw material for national economic development. recycled aluminum is one of the most abundant metallic elements in the world, and its reserves rank the first among metals.It was not until the end of the 19th century that aluminum emerged as a competitive metal for engineering applications and was all the rage.The development of the three important industries of aviation, construction and automobile requires that the material properties have the unique properties of aluminum and its alloys, which greatly facilitates the production and application of this new metal -- aluminum.
