Features Of Aluminum And Aluminum Alloys:

- Apr 04, 2019-

1. Low density,

The density of aluminum is 2.7g/cm3, and the second light metal in magnesium metal structure is only higher than magnesium, only 1/3 of iron or copper.

 

2. High plasticity

Aluminum and its alloys have good ductility and can be made into various types, plates, foils, tubes and wires by pressure processing such as extrusion, rolling or drawing.

 

3. Easy to strengthen

Pure aluminum is not strong, but it is easily strengthened by alloying and heat treatment to produce high-strength aluminum alloy, which is comparable in strength to alloy steel.

 

4. Good conduction

The electrical and thermal conductivity of aluminum is second only to silver, gold and copper.

 

5. Corrosion resistance

Aluminum and oxygen have a very high affinity. Under natural conditions, aluminum surfaces form protective oxides, which have much better corrosion resistance than steel.

 

6. Easy to recycle

The melting temperature of aluminum is low, about 600 ° C, the fertilizer is easy to regenerate, the recovery rate is extremely high, and the energy consumption for recovery is only 3% of smelting.

 

7. Can be welded

The aluminum alloy can be welded by inert gas protection method. After welding, the mechanical properties are good, the corrosion resistance is good, the appearance is beautiful, and the structural material requirements are met.

 

8. Easy surface treatment

Aluminum can be anodized and colored, with high hardness after treatment, good wear resistance, corrosion resistance and electrical insulation. It can also be used for electroplating, electrophoresis, spraying, etc. to further improve the decorative and protective properties of aluminum.
