6061 automotive aluminum tube

6061 is a heat treatment strengthening alloy with good formability, weldability, machinability, medium strength and good operability after annealing
The main alloying elements of 6061 automotive aluminum tube are magnesium and silicon, which form Mg2Si phase. If there is a certain amount of manganese and chromium, it can neutralize the bad effect 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 a small amount of copper in the conductive material to offset the adverse effects of titanium and iron on the conductivity; zirconium or titanium can refine the grain and control the recrystallization structure; in order to improve the machinability, lead and zinc can be added Bismuth. When Mg2Si is dissolved in aluminum, the alloy has the function of artificial aging hardening.

6061-T651 is the main alloy of 6061 alloy. It is a high-quality automotive aluminum tube produced by heat treatment and pre stretching process. Although its strength can not be compared with that of 2XXX or 7xxx series, it has many magnesium and silicon alloy characteristics, excellent processability, excellent welding characteristics and electroplating, good corrosion resistance, high toughness, no deformation after processing, compact and defect free material, and easy polishing and coloring The membrane is easy to oxidize and has excellent oxidation effect.
6061 automotive aluminum tube is widely used in aerospace fixture, electrical fixture and communication field. It is also widely used in automatic mechanical parts, precision machining, mold manufacturing, electronics and precision instruments, SMT, PC board solder carrier and truck, Tower buildings, ships, trams, furniture, pipes and other areas that require strength, weldability and corrosion resistance.
