La 6061 et 7005 les bobines d'aluminium sont les représentants de la 6 bobine en aluminium de série et 7 bobines en aluminium de série. Ils sont tous deux des bobines en alliage d'aluminium très matures et sont largement utilisés dans l'industrie et la vie. Parmi eux, 6061 est le nom de code d'un alliage d'aluminium principalement dopé avec 1% magnésium et 0.6% silicium, et 7005 est aussi le nom de code d'un alliage d'aluminium principalement dopé avec 4.5% zinc et 1.4% magnésium. And what are the differences between the two types of aluminum coils?

Tout d'abord, the heat treatment process: T6 is a heat-treatment process. Par exemple, 6061-T6 is a 6061 aluminum coil that has undergone T6 heat treatment. 7005 T6 Tensile is 51000 PSI, 6061 T6 Tensile is 45000 PSI; 7005 T6 Volatility is 42000 PSI, 6061 T6 Volatility is 40000 PSI.

De cette façon, 7005 bobine d'aluminium is stronger than 6061 bobine d'aluminium, mais 6061 aluminum is more willful than 7005 aluminium, but the different characteristics between the two are still different.
t6 is the nominal 20-hour tempering t treatment, and there is also a 10-hour tempering t4 heat treatment, etc.

Some aluminum coils say 6061 aluminium, some say 6011, some say 7005…
Some people think that the larger the number of aluminum coil number, the more expensive and better the aluminum coil, and the stronger the performance (performance includes factors such as lightweight, haute résistance, durabilité, etc.), but this view is wrong.
Tout d'abord, let us first understand the specific meaning and difference of aluminum material numbers:
1 bobine en aluminium de série (representing pure aluminum! The aluminum content is not less than 99%)
2 bobine en aluminium de série (mainly copper alloy)
3 bobine en aluminium de série (main manganese)
4 bobine en aluminium de série (mainly silicon)
5 bobine en aluminium de série (main magnesium)
6 bobine en aluminium de série (mainly magnesium and silicon)
7 bobine en aluminium de série (mainly zinc)
8 bobines en aluminium de série (Other Elements)

The characteristics of 6 series aluminum are medium strength, good plasticity, and excellent corrosion resistance. In particular, it has no tendency to stress corrosion cracking and has excellent weldability, résistance à la corrosion, and cold workability. It is a promising alloy with a wide range of applications.

The 7-series aluminum alloy is another commonly used alloy and comes in a wide variety. It contains zinc and magnesium. The most common aluminum alloy is the 7075 alliage, but it cannot be welded, and its corrosion resistance is quite poor. Zinc is the main alloying element in this series, plus a little magnesium alloy. The material can be heat treated to achieve very high strength properties.

This is only relative if you have to ask “if it is the same forging process and the same welding method, but only the aluminum coil is different, which product is better?” It should be 7005 aluminum in terms of weight, force, etc. Slightly better than 6061 aluminium.
In fact, the common application and forging methods between the two are different, and the performance is also different due to different applications, so it is not possible to judge which of the two aluminum coils is better just by the size of the model.
