Product Introduction
Ordinary duralumin alloy, good machinability, with medium strength
6061 is a heat-treated reinforcable alloy with good formability, weldability, machinability, and medium strength, and can maintain good operability after annealing.
The main alloying elements of Alloy 6061 are magnesium and silicon which form the 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 also a small amount of copper in the conductive material to offset the adverse effects of titanium and iron on conductivity; Zirconium or titanium can refine grains and control recrystallization structure; To improve machinability, lead and bismuth can be added. In Mg2Si is solidly soluble in aluminum, so that the alloy has the function of artificial aging hardening.
6061-T651 is the main alloy of 6061 alloy, a high-quality aluminum alloy product produced by heat treatment pre-stretching process, although its strength can not be compared with the 2000 series or 7000 series, its magnesium, and silicon alloy characteristics, with excellent processing performance, and excellent welding characteristics and plating, good corrosion resistance, high toughness and no deformation after processing, dense and defectless material and easy polishing, easy coloring film, excellent oxidation effect and other excellent characteristics.
