> 6063 marine grade aluminium rod bar

6063 aluminium rod is a low alloyed Al-Mg-Si series high plastic alloy, with many valuable features:

1. Heat treatment to strengthen, high impact toughness, the lack of insensitivity.
2. Excellent thermoplastics, high-speed extrusion into complex structures. Thin-walled. Hollow various profiles or forging into complex structural forgings, quenching temperature range, low sensitivity to quenching, extrusion and forging demolding, As long as the temperature is higher than the quenching temperature. That can be sprayed or water quenching method. Thin-walled parts (6 <3mm) can also be air-quenched.
3. Excellent weldability and corrosion resistance, no stress corrosion cracking tendency. Al-Mg-Si alloy is the only alloy that has not found any stress corrosion cracking in the heat-treatable aluminum alloy.
4. After processing the surface is very smooth, and easy anodizing and coloring. The disadvantage is that if parked at room temperature for some time after quenching, aging will have an adverse effect on the strength (parking effect).

Effect of alloying elements on performance:
6063 aluminum alloy is a heat-treatable strengthening alloy with moderate strength in AL-Mg-Si series. Mg and Si are the main alloying elements. The main work of the preferred chemical composition is to determine the percentage contents of Mg and Si (mass fraction) .
1.1 Mg role and influence Mg and Si composition strengthening phase Mg2Si, Mg content higher, the greater the number of Mg2Si heat treatment to strengthen the greater the tensile strength of the profile, the higher, but the deformation resistance also with The plasticity of the alloy decreases, the processability deteriorates and the corrosion resistance deteriorates.
1.2 The role of Si and the impact of the amount of Si should make all the Mg alloy Mg2Si phase can exist in order to ensure the full play of the role of Mg. With the increase of Si content, the grain of the alloy becomes thinner, the fluidity of the metal increases, the casting properties become better, the heat treatment strengthening effect increases, the tensile strength of the profile increases, the plasticity decreases and the corrosion resistance deteriorates.
