Aluminum is a metal with the symbol Al and a density of 2.70 g / cm3. It is non-toxic and magnetic, non-sparking, resistant to cold and heat, products with precise tolerance can be produced. Its density is one third of steel or copper, it is easily malleable, machinable and castable, and reflects excellent light. While the tensile strength of pure aluminum is 49 MPa, it can reach up to 700 MPa (Megapascals) when alloyed.

While it has a fully recyclable feature, its alloys can be even more durable than steel.

While it finds wide use in the transportation and construction sectors that require lightness and high strength features, it has also become an indispensable part of the space and aviation industry.

It has very superior corrosion properties because the oxide layer formed on it is protective.

Aluminum Alloys

Alloy Main Element Effect of Main Element

1000A: None High corrosion resistance, low strength, good conductivity
2000A: Copper Strength, hardness and machinability, Can be hardened by heat treatment
3000A: Manganese Medium strength, good workability
5000A: Magnesium Medium and good strength, good workability
6000A: Magnesium Silica. Formability, corrosion resistance, high strength
7000A: Zinc Very high strength, can be hardened by heat treatment

1000,3000,5000 and 6000 series alloys have good weldability and corrosion resistance. The 2000 and 7000 series alloys have higher strength and machinability, but low weldability and corrosion resistance.
