Product details
The representative uses of 6061 aluminum bars include aerospace fixtures, electrical fixtures, and communications. They are also widely used in automated mechanical parts, precision machining, mold manufacturing, electronics and precision instruments, SMT, PC board solder carriers, etc. Introduction It is a heat-treatment-strengthened alloy with good formability, weldability, machinability, and medium strength. It can still maintain good operability after annealing. The main alloying elements of 6061 alloy are magnesium and silicon, and they form Mg2Si phase.
6061-T651 is the main alloy of 6061 alloy. It is a high-quality aluminum alloy product produced by heat treatment pre-stretching process. Although its strength cannot be compared with 2XXX series or 7XXX series, it has many magnesium and silicon alloy characteristics, excellent processing performance, excellent welding characteristics and electroplating, good corrosion resistance, high toughness and no deformation after processing, dense material without defects and easy polishing, easy color film, excellent oxidation effect and other excellent characteristics.
Typical uses:
1. Application of plates and strips is widely used in decoration, packaging, construction, transportation, electronics, aviation, aerospace, weapons and other industries.
2. Aluminum for aerospace is used to make aircraft skins, fuselage frames, beams, rotors, propellers, fuel tanks, wall panels and landing gear struts, as well as rocket forging rings, spacecraft wall panels, etc
3. Aluminum for transportation is used for body structural materials of automobiles, subway vehicles, railway passenger cars, and high-speed passenger cars, car doors and windows, shelves, automobile engine parts, air conditioners, radiators, body panels, wheels and ship materials.
4. Aluminum for packaging: All-aluminum cans are mainly used as metal packaging materials in the form of thin plates and foils to make cans, lids, bottles, barrels, and packaging foils. Widely used in the packaging of beverages, food, cosmetics, medicines, cigarettes, industrial products, etc.
5. Aluminum for printing is mainly used to make PS plates. Aluminum-based PS plates are a new type of material in the printing industry, used for automated plate making and printing.
