Why choose 6063 for broken bridge aluminum doors and windows?
According to the hardness, from big to small is 7, 2, 6, 5, 3. These series represent 7075, 2024, 6063, 5052, 3003. If it is to consider the strength you can give priority to 7 series and 2 series. These two series can be called super-hard aluminum and hard aluminum.
If cutting, 7, 2, 6 are all appropriate. If stamping, only 3, 5 is the most suitable.
In terms of the transparency of the anodized film, it is 5, 6, 3, 2, 7. So when choosing decorative parts, we usually use the 5 series, for example, we use 5052 for cell phone cases.
6 series aluminum alloy in high temperauture (such as fire conditions) corrosion-resistant conditions (rain, etc.) than 2 series and 7 series have obvious advantages.
But the windows and doors are hardness and requirements of processing requirements, while there is a need for anodic oxidation film protection, then the general choice of 6 series of broken bridge. So broken windows and doors usually choose 6063 series.
Broken bridge windows and doors mainly use 6063-T5 series, because it can be suitable for making complex sections, very suitable for roller pressure spacer bars, while not prone to bridging.
The hardness of 6063-T6 profile is higher than that of 6063-T5, which is only suitable for large-scale curtain wall and high-strength sunroom, because of the high hardness, it will be fractured when wearing the heat insulation strip roller pressing.
What is the difference between 6063-T5 and 6063-T6 that we often see, and also what is the difference between 6063 and 6063A?
In fact, T6 indicates that when the aluminum profile is extruded using water cooling or liquid nitrogen for cooling, T5 indicates the use of air cooling or natural cooling in the air; with A on behalf of the type and content of the alloy is different, generally 6063A tensile strength is a little stronger.
7xxx series
7xxx series mainly contains zinc elements, but also contains magnesium and copper elements. It is an aluminum-magnesium-zinc-copper alloy, which can be heat-treated alloy super-hard aluminum alloy. With wear resistance.
The main representative of the 7xxx series is 7075 series, belonging to the aviation materials and mould materials. But now mainly rely on imports, our production process is still not too good for the time being.
Now there are a lot of sales of broken bridge that they use 7075 aircraft aluminum, this statement is debatable, the first point is that his high strength is not suitable for heat insulation strip roll pressure will fracture, the second simple 7075 series corrosion resistance is not high. So be careful when buying.
8xxx series
8000 series aluminum alloy is more commonly used for 8011 belongs to other series, most of the applications for aluminum foil, the production of aluminum rods are not commonly used.
