6061 aluminum rods are the main alloying elements of magnesium and silicon, and the formation of Mg2Si phase. If you contain a certain amount of manganese and chromium, can neutralize the bad role of iron; sometimes add a small amount of copper or zinc, in order to improve the strength of the alloy, but not to significantly reduce the corrosion resistance; conductive materials, there are a small amount Of copper 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 bismuth can be added.
6061-T651 is the main alloy of 6061 alloy, is the heat treatment pre-stretching process to produce high-quality aluminum alloy products, although its strength can not be compared with 2XXX or 7XXX system, but its magnesium, silicon alloy characteristics, with processing performance Excellent, excellent welding characteristics and electroplating, good corrosion resistance, high toughness and deformation after processing, material is not defective and easy to polish, easy to color film, excellent oxidation and other excellent features. Typical use First, the application of strip is widely used in decoration, packaging, construction, transportation, electronics, aviation, aerospace, weapons and other industries. Second, aerospace aluminum for the production of aircraft skin, body frame, beam, rotor, propeller, fuel tank, siding and landing gear pillars, as well as rocket forging ring, spacecraft wall panels. Third, the transport of aluminum for the automotive, subway vehicles, rail passenger cars, high-speed bus body structure materials, doors and windows, shelves, car engine parts, air conditioners, radiators, body panels, wheels and ship timber. Fourth, the packaging of aluminum aluminum cans can be mainly in the form of sheet metal and foil as a metal packaging materials, made of cans, caps, bottles, barrels, packaging foil. Widely used in beverages, food, cosmetics, pharmaceuticals, cigarettes, industrial products and other packaging. Fifth, the printing of aluminum is mainly used for the production of PS version, aluminum PS version of the printing industry is a new type of material for automated plate making and printing.
