7005 aluminum alloy Name: Wrought aluminum and aluminum alloy grades: 7005 Properties and Applications: 7005 aluminum alloy, aluminum and aluminum alloy deformed the United States. 7005 alloy strength is higher than 7003, good weldability, can be heat strengthened. 7005 aluminum extrusion materials, often used in manufacturing have both high strength but also have high fracture toughness of welded structures, such as truss transportation vehicles and pole container; large heat exchangers, and can not be performed after welding solid solution components processing; also used in the manufacture of sports equipment such as tennis rackets and baseball bats. Standard control: American Aluminum Association (AA) 7005, UNS A97005; China GB 7005; Japanese JIS (7N11) chemical composition: aluminum Al (minimum): margin silicon Si: ≤0.35 iron Fe: ≤0.40 Copper Cu: ≤ 0.10 Manganese Mn: 0.20 ~ 0.7 Magnesium Mg: 1.0 ~ 1.8 Chromium Cr: 0.06 ~ 0.20 Zinc Zn: 4.0 ~ 5.0 Zirconium Zr: 0.08 ~ 0.20 Titanium Ti: 0.01 ~ 0.06 unspecified other elements: each: ≤0.05; Total : ≤0.15 7005 aluminum alloy mechanical properties: 7005 material condition: T1 T3 T4 T5 T6 T8 manufacturing method: drawing mechanical properties: state tempert4: tensile strength uts324, non-proportional elongation stress yield215, elongation elongation11, conductivity 40-49 Status tempert5: tensile strength uts345, non-proportional elongation stress yield305, elongation elongation9, conductivity 40-49; state tempert6n: uts350 tensile elongation stress yield290 non-proportional elongation elongation8 Conductivity 40-49 6061,7005,7075 difference of aluminum alloy: aluminum hardness is not high, relatively soft, but the alloy on hard. By adding different metals can get a variety of alloys are aluminum models 6061,7005,7075. 6061 is the most common aluminum, light, strength, and affordable. 7005 is a lightweight aluminum, as strong as 6061, but a lot of light, the price is high. 7075 is the lightest and highest strength aluminum, the price is super expensive! Strength steel of less than 7075. Specific differences 6061,7005 aluminum: 1. Current material commonly used aluminum frame is 7005 and 6061 two kinds. 2.7000 series of mainly zinc as the main alloy component ratio of 6%. 6000 series mainly magnesium and silicon as the main alloying lower proportion of the total composition. 3. On the strength of strong words of 7005, but just a little bit stronger, can be seen from the table, yield strength (make aluminum permanent bending strength) is only a little better than 6061. 4. All materials used for the frame are heat-treated aluminum alloy T6 5. But on the whole is concerned, 6061 is a better material. Since 7005 containing a high proportion of other metals, the welding, it is more difficult to handle, especially in 7075 (the latter two figures represents an alloy ratio) higher proportion of it, it is generally not used as the frame material. In contrast, 6061 due to the other metals containing low proportion, it can be increased by profiled various processes its strength and reduce its wind resistance, or even can be done three times butted to reduce weight.
