铝合金名称

    The aluminum industry uses a four-digit index system for the designation of its wrought aluminum alloys.
    As outlined below, the first digit indicates the alloy group according to the major alloying elements.

    1xxx Series
    In this group minimum aluminum content is 99% and there is no major alloying element. The second digit indicates modifications in impurity limits. If the second digit is zero, there is no special control on individual impurities. Digits 1 through 9, which are assigned consecutively as needed, indicate special control of one or more individual impurities. The last two digits indicate specific minimum aluminum content. Although the absolute minimum aluminum content in this group is 99%, the minimum for certain grades is higher than 99%, and the last two digits represent the hundredths of a per cent over 99. Thus, 1030 would indicate 99.30% minimum aluminum. without special control on individual impurities. The designations 1130, 1230, 1330, etc.. indicate the same purity with special control on one or more impurities. Likewise 1100 indicates minimum aluminum content of 99.00% with individual impurity control.

    2xxx至9xxx系列
    The major alloying elements are indicated by the first digit, as follows:
      2xxx Copper
      3xxx Manganese
      4xxx Silicon
      5xxx Magnesium
      6xxx Magnesium and silicon
      7xxx Zinc
      8xxx Other element
      9xxx Unused series

    第二个数字表示合金修饰。如果第二位数为零。它指示原始合金:数字1至9,连续分配,指示合金修饰。最后两个数字没有特殊的意义,仅用于识别该组中的不同合金。

    实验合金
    实验合金是根据四位数系统指定的,但是它们的前缀为字母X。当合金成为标准配合时,前缀被删除。在开发过程中,在将它们指定为实验之前,新合金由其发起人分配的序列号确定。分配X号时停用序列号的使用。

  • 1Based on 500,000.000 cycles of completely reversed stress using the R. R. Moore-type of machine and specimen.
  • 2Average of tension and compression moduli. Compression modulus is about 2 percent greater than tension modulus.
  • 3Ratings A through E are relative ratings in decreasing order of merit, based on exposures to sodium chloride solution by intermittent spraying or immersion. Alloys with A and B ratings can be used in industrial and seacoast atmospheres without protection. Alloys with C, D and E ratings generally should be protected at least on faying surfaces.
  • 4Ratings A through D for Weldability and Brazeability are relative ratings.
  • 5A = Generally weldable by all commercial procedures and methods.
    B = Weldable with special techniques or for specific applications that justify preliminary trials or testing to develop welding procedure and weld performance.
    C = Limited weldability because of crack sensitivity or loss in resistance to corrosion and mechanical properties.
  • 6A = Generally weldable by all commercial procedures and methods.
    B = Weldable with special techniques or for specific applications that justify preliminary trials or testing to develop welding procedure and weld performance.
    C = Limited weldability because of crack sensitivity or loss in resistance to corrosion and mechanical properties.
  • 7A = Generally weldable by all commercial procedures and methods.
    B = Weldable with special techniques or for specific applications that justify preliminary trials or testing to develop welding procedure and weld performance.
    C = Limited weldability because of crack sensitivity or loss in resistance to corrosion and mechanical properties.
