Aluminum curtain wall is mainly made of high-quality aluminum alloy through sheet metal and spraying and other processes. The main models of common aluminum veneer substrate are 1100H24, 1060H24, 3003H24 and 5005H24. Below blue sky seven color group to take you to understand the characteristics of a few kinds of aluminum alloy.
Both types of aluminum alloys are subject to “H24” in the above models, where H is short for English abrasion, “H2” for machining a movement and incomplete annealing, and H24 for “semi-hard” states subject to process hardening.
1100H24 and 1060H24 aluminum alloys are 1XXX aluminum alloys, also known as “pure aluminum”, which are generally not used for hard anodic oxidation. This aluminum alloy has a high content of aluminum, containing more than 99.00% of aluminum. This type of aluminum alloy has good electrical conductivity, excellent corrosion resistance and weldability, but the disadvantage is that heat treatment can not be strengthened.
3003H24 aluminum alloy belongs to 3XXX series aluminum alloy, also known as “aluminum-manganese alloy”, the content of manganese is between 1.0 and 1.5, the rust prevention function is good. The strength of this aluminum alloy is slightly higher than that of industrial pure aluminum, and it has good plasticity, good corrosion resistance and good weldability in annealed state.
The defect of this aluminum alloy is its poor machinability.
5005H24 belongs to the 5XXX series aluminum alloy, the main element is aluminum magnesium element, contains magnesium content between 3%-5%, also known as “aluminum magnesium alloy”, the main characteristics are low density, high tensile strength, high elongation. In the same area, the weight of al – Mg alloy is lighter than other series of al – mg alloy, which is widely used in industry. The disadvantage is that if the magnesium content is high, the brightness will not be enough.
Therefore, in the production of aluminum curtain wall, according to the construction requirements of customers to choose a reasonable aluminum alloy model for processing.
