6063 aluminium alloy introduction

6063 aluminium alloy is a representative alloy product of 6000 series aluminium. After testing aluminium grade 6063, under certain pressure and certain temperature conditions, the plastic properties and corrosion resistance are good, and there is no tendency to stress corrosion. At the same time, 6063 is also a representative alloy for extrusion with a strength lower than 6061 aluminum sheet, but it has good performance and belongs to Al-Mg-Si series high plastic alloy.


Characteristics of 6063 aluminium alloy

6063 aluminium alloy has many valuable features, specifically the following points.
1) 6063 aluminium alloy not only has strong extrudability and good thermoplasticity, it can also be strengthened by heat treatment
2) Aluminium grade 6063 has a wide quenching temperature range and low quenching sensitivity. After extrusion and forging, if the temperature is higher than the quenching temperature, it can be quenched by water spray or water penetration.
3) Aluminium alloy 6063 is an Al-Mg-Si alloy which is an alloy where stress corrosion cracking has not been found. And it has excellent welding performance and corrosion resistance.
4) 6063 alloy has smooth surface treatment, and is easy to anodize and color.


Effect of Si on the performance of 6063 aluminium alloy

The Si element enables all Mg elements in 6063 aluminium alloy to exist in the chemical form of Mg₂Si to ensure that the role of Mg is fully exerted. As the Si content increases, the grains of the alloy become finer, the metal fluidity increases, the casting performance becomes better, and the heat treatment strengthening effect increases.


Effect of Mg element on the properties of 6063 aluminium alloy

Mg and Si constitute the strengthening phase Mg₂Si. The higher the Mg content, the greater the amount of Mg₂Si, the greater the heat treatment strengthening effect, and the higher the tensile strength of 6063 aluminium alloy.

Application of aluminium grade 6063

The strength of 6063 aluminum sheet plate is slightly lower than 6061 aluminum sheet. Combined with the introduction above, it looks that aluminium grade 6063 has good plasticity, corrosion resistance and surface treatment. Therefore, 6063 grade is a better base material for making profiles. It is widely used in the framework of building aluminum doors, windows and curtain walls. It ensure that the doors, windows and curtain walls have high wind pressure resistance, assembly performance, corrosion resistance and decorative performance.

6063 aluminium alloy sheet application on mobile phones

6063 aluminium alloy sheet can be applied to the manufacture of the frame of the mobile phone’s shell. At present, the mobile phone shell making often use anodizing technology. This process of oxidative coloring on the appearance of aluminium grade 6063 sheet to form a strong oxide film. Then the mobile shell of aluminum alloy surface is colored and forms a protective film.


6063 aluminium alloy sheet coil from Mingtai Aluminum is easy to process and shape. Mingtai has 23 years of aluminum alloy production experience and 15 years of foreign trade experience.
