Aluminum is a common metal in daily life. The aluminum content of pure aluminum is very high, and its strength and toughness can not reach the application standard. It is necessary to form different types of aluminum alloy profiles by adding some different metal elements. Here is a brief introduction Aluminum profile How many specifications are there and how many are different Specifications What are the uses of aluminum profiles.
Aluminum elements and other metal elements through the synthesis of different specifications and aluminum alloy profiles, then we briefly introduce how many specifications of aluminum alloy profiles are mainly divided into;
one Series aluminum alloy ( Pure aluminum alloy) with aluminum content up to 99% above;
two Series aluminum alloy profiles（ Al-Cu Alloy);
three Series aluminum alloy profiles（ Al-Mn Alloy);
four Aluminum alloy profiles（ Al-Si Alloy);
five Series aluminum alloy profiles（ Al-Mg Alloy);
six Series aluminum alloy profiles（ Al-Mg-Si Alloy);
seven Series aluminum alloy profiles（ Al-Zn-Mg Alloy);
one The series alloys are pure aluminum series alloys with aluminum content up to 99% Above, mainly divided into the following several Specifications ： one thousand and fifty 、 one thousand and sixty 、 one thousand and seventy 、 one thousand and eighty 、 one thousand and eighty-five 、 one thousand and one hundred 、 one thousand and two hundred Because the purity of aluminum is inversely proportional to its strength, that is, the higher the purity, the lower the strength one The strength of the alloy is very low, and the production process is relatively simple, so the price is relatively cheap. It can be used to produce daily necessities, aluminum plates, chemical industrial containers and conductive materials.
two Copper is added to the alloy, and the content of copper is relatively high. Therefore, it has a good anti rust function, mainly including the following specifications: two thousand and eleven 、 two thousand and seventeen 、 two thousand and eighteen 、 two thousand and twenty-four 、 two thousand and twenty-five 、 two thousand one hundred and seventeen 、 two thousand two hundred and eighteen 、 two thousand two hundred and nineteen It has high strength, can adapt to both high temperature and low temperature environment, and has good solubility, but its corrosion resistance is not so good, so it can be used for aviation Aluminium Optical components, gears, pistons and oil pressure components.
three The results show that the strength ratio of the alloy is higher than that of the alloy one In series alloys one thousand and one hundred It's about higher than that 10% In which three thousand and five Strength ratio three thousand and three It's stronger again 20% ， three thousand one hundred and five Strength ratio three thousand and three The strength of the alloy is slightly higher than that of the alloy three thousand and three 、 three thousand and four 、 three thousand and five 、 three thousand one hundred and four 、 three thousand one hundred and five 、 3A21 And so on, three The alloy has good formability, good solubility and good corrosion resistance. It can be used to produce oil guide pipe of aircraft fuel tank, drum, radiator, cosmetic plate, bottle cap, can, colored aluminum plate and building materials.
four Silicon is added to the alloy, and the content of silicon is also very high. It is generally used in building materials, such as building panel, dissolving line, etc. because of its good fluidity and low thermal expansion coefficient when heated, it can be used to make piston and cylinder head four thousand and thirty-two 、 four thousand and forty-three Compared with other series of alloys, the application range is not particularly large.
five It is easy to form, has good fatigue resistance, high strength, corrosion resistance, especially good seawater resistance. After anodizing, the color is very natural gray, which looks beautiful, five thousand and fifty-two Alloy is the most medium strength aluminum alloy five thousand and five 、 five thousand and fifty 、 five thousand and fifty-two 、 five thousand and fifty-six 、 five thousand and eighty-three 、 five thousand and eighty-six 、 five thousand one hundred and fifty-four 、 five thousand one hundred and eighty-two 、 five thousand two hundred and fifty-four 、 five thousand four hundred and fifty-four Etc., and two A little similar is that it can be used in both low and high temperature environments. Based on its good sea water resistance, it can be used to manufacture ships, pressure vessels, bulletproof vests, tank covers, car wheels, cameras, etc.
six It is the most widely used alloy with magnesium and selenium four Tie and five The advantages of the series of alloys are integrated six thousand and sixty-one 、 six thousand and sixty-three 、 six thousand and eighty-two 、 six thousand two hundred and sixty-two 、 six thousand and sixty 、 six thousand one hundred and one 、 six thousand one hundred and fifty-one 、 six thousand two hundred and sixty-two and 6N01 In which six thousand and sixty-one and six thousand and sixty-three The representative alloy is widely used in industrial aluminum profiles, six thousand and sixty-one It belongs to heat treatment type alloy T5 or T6 High endurance value can be obtained by the treatment method of, 6N01 The alloy has medium strength and strong corrosion resistance, six thousand one hundred and one It not only has high strength, but also has good conductivity, six thousand two hundred and sixty-two Corrosion resistance ratio of alloy two thousand and eleven Even better. six It can be used to manufacture ships, vehicles, cross-section profiles with complex shapes, popular aluminum profiles for home furnishings, all kinds of machinery, automobile accessories, new-type automobile body, new logistics vehicle all aluminum carriage frame Aluminum type material , as well as various components and aluminum profile luggage rack, which are widely used in industrial production.
seven It is a kind of super hard aluminum alloy. Its hardness is close to that of steel seven thousand and seventy-five The alloy has the highest strength in aluminum alloy, but its corrosion resistance is not very good, seven thousand and fifty The corrosion resistance of the alloy should be better, seven The alloy has high hardness, strong wear resistance and weldability. It is mainly used in aerospace, aircraft, landing gear, rocket, spaceship, ski battle, vehicle, motor vehicle wheel outer ring, propeller, etc seven thousand and three 、 seven thousand and five 、 seven thousand and fifty 、 seven thousand and seventy-two 、 seven thousand and seventy-five Wait, especially seven thousand and five and seven thousand and seventy-five Alloy is the representative of high-end aluminum alloy.
