The use and application prospects of aluminum


                                            southwest aluminum

INTRODUCTION 

As a result of the aluminum reserves are abundant, with more excellent performance at the same time, it also determines the aluminum is widely used in industry and life, let's according to the performance of it simply introduces the application of the aluminum.


DENSITY IS SMALL

Aluminum alloy power cable the density of aluminum is 2.7 g/cm after (a third of the density of iron, copper), good ductility, two-thirds of the conductive ability for copper wire, but the quality is only one-third of the price compared with cheaper, a large number of used in the manufacture of high voltage wire, cable, radio industry.

Pure aluminum density is relatively low, but the density and hardness of aluminum alloy are greatly improved. At present, aluminum alloy has been widely used in manufacturing industries such as airplanes, automobiles, trains and ships.

In addition, space rockets, space shuttles, and satellites also use a large amount of aluminum and aluminum alloys.


THERMAL CONDUCTOR

Aluminum is a good conductor of heat (three times the thermal conductivity of iron), and it can be used to make all kinds of heat exchangers, heat dissipating materials and cooking utensils.


THE DUCTILITY

Aluminum has good ductility (second only to gold and silver), in 100 ℃ ~ 150 ℃ can be made into thin 0.01 mm aluminum foil.

These aluminum foil are widely used in packaging cigarettes, candy, etc., and can be made into aluminum wire and aluminum bars, and can be rolled into various aluminum products.


CORROSION RESISTANT

In the air, the surface of aluminum can form dense oxide film, make its corrosion resistance, so often be used to produce medical equipment, chemical reactor, freezer, oil refining equipment, oil and gas pipelines, etc.



CATALYST

Aluminum thermals are often used to melt refractory metals and welded rails.

Aluminum is also used as a deoxidizer in the process of making steel.

Aluminum powder and graphite, titanium dioxide (or other high melting point metal oxide) according to certain ratio after mixing, besmear is on metal, made by high temperature calcination and high-temperature metal ceramic, has important application in rocket and missile technology.
