Quels sont 1, 2, 3, 4, 5, 6, 7, 8 series aluminum alloys？

What does the number number of the aluminum alloy represent? Quels sont les modèles courants en alliage d'aluminium? Dans le dernier article, nous avons partagé les significations et les modèles de produits communs de l'aluminium 1000 séries et 2000 numéros de métal en aluminium de série. Aujourd'hui, we continue to share the digital meanings and common aluminum alloy models of 3, 4, et 5 series aluminum alloy products.

Ⅰ: 3 series aluminum products

le 3000 series alloy is mainly composed of Mn (content in the range of 1.0-1.5) + Al metal. Parmi eux, the representative alloy models are 3003 3004 3A21. 3 series aluminum alloys are commonly used in household appliances, body frames, etc. It has the characteristics of good corrosion resistance and rust resistance. The price is higher than the first series.

Ⅱ: 4 alliage d'aluminium de série.

le 4000 series aluminum alloy is mainly Al+Si (content is 4.5-6.0%) metal, and the silicon content is relatively high. Parmi eux, the representative models of 4 series aluminum metal are 4A01, 4006, 4007, 4015, 4047. 4 series aluminum products are mostly used in architectural scenes and belong to building materials. It is also commonly used in mechanical parts, welding materials, instructions de production d'emballages en papier d'aluminium; it has the characteristics of low melting point and good corrosion resistance.

Ⅲ: 5 series aluminum products.

5000 series is a relatively common type of aluminum alloy. It uses Mg (with magnesium content between 3-5%) as the main alloy and has the characteristics of low density and super tensile strength. Common 5-series alloy models represent the 5052.5005.5083.5A05 series.
The elongation of 5-series alloys is very good, and they are mostly used in aerospace materials, such as aircraft chassis.
In China, la 5000 series aluminum alloy is one of the more mature aluminum alloy product series.
