Product Description

The main alloying elements of 6061 aluminum rod are magnesium and silicon, and form Mg2Si phase. If it contains a certain amount of manganese and chromium, it can neutralize the bad effects of iron; sometimes a small amount of copper or zinc is added to improve the strength of the alloy without significantly reducing its corrosion resistance; there is still a small amount of conductive material. Copper to offset the adverse effects of titanium and iron on electrical conductivity; zirconium or titanium can refine grains and control recrystallization structure; in order to improve machinability, lead and bismuth can be added. 6061-T651 is the main alloy of the 6 series alloy, and it is a high-quality aluminum alloy product that has undergone heat treatment and pre-stretching. Although its strength cannot be compared with 2XXX series and 7XXX series, its magnesium and silicon alloys have many characteristics and excellent Excellent processing performance, excellent welding characteristics and electroplating, good corrosion resistance, high toughness and no deformation after processing, dense material without defects and easy to polish, easy to color film, excellent oxidation effect and other excellent characteristics.

6063 aluminum rod is a low alloyed Al-Mg-Si series high plasticity alloy. It has many valuable features:

1. Strengthened by heat treatment, high impact toughness, and insensitive to missing.

2. With excellent thermoplasticity, it can be extruded at high speed into complex, thin-walled and hollow profiles or forged into forgings with complex structure, wide quenching temperature range, low quenching sensitivity, after extrusion and forging demoulding, as long as the temperature is higher than the quenching temperature. It can be quenched by water spray or water penetration. Thin-walled parts (6<3mm) can also be air quenched.

3. Excellent welding performance and corrosion resistance, no stress corrosion cracking tendency. Among the heat-treatable-strengthened aluminum alloys, Al-Mg-Si alloys are the only alloys that have not found stress corrosion cracking.

4. The surface after processing is very smooth and easy to anodize and color.
