Belonging to 6061 genera and strengthens the alloy heat treatment, with good formability and weldability, processability, with moderate intensity at the same time, can still maintain a good operational after annealing.
6061 alloy magnesium and silicon are the main alloy elements, and formed Mg2Si phase. If contains a certain amount of manganese and chromium, can counteract the bad effect of iron; Sometimes add a small amount of copper or zinc, in order to improve the strength of the alloy, and don't make it have a significantly lower resistance to corrosion; Conductive material with a small amount of copper, in order to offset the bad influence of titanium and iron for electrical conductivity; Zirconium or titanium can refine grain and controlling recrystallization organization; In order to improve cutting performance, can be added to the lead and bismuth. In Mg2Si solid soluble in aluminum alloy artificial aging hardening function.
6061 - T651 is the main alloy, alloy 6061 is the pre-draft heat treatment process of high quality aluminum alloy products, its strength is not compared with 2 or 7 XXX XXX department system, but its more magnesium, silicon alloy properties, has the excellent processing performance, excellent welding characteristics and electroplating, good corrosion resistance, high toughness and processing after deformation, dense material without defects and easy polishing, coloring film easily, good features such as oxidation excellent results.
Aluminum alloy is the most widely used in industry of non-ferrous metal structural materials, in aviation, aerospace, automotive, machinery manufacturing, shipping and have been extensively applied in chemical industry. The rapid development of industrial economy, the demand for aluminum alloy welding structure is increasing, also make the weldability of aluminum alloy and research.
