Strength of non-ferrous fasteners

Class合金番号強度区分Applicable nominal diameterTensile strength
Min. [N/mm2]
0.2 % proof strength
Min. [N/mm2]

Notes

  • There is no property class.Unlike steel and stainless steel, the strength is set by the material group (CU1, AL1 and so on) and the alloy designation.
  • Within one material group the values still change with the nominal diameter.The size boundaries differ between groups, so check the nominal diameter column.
  • JIS B 1057 specifies the mechanical properties at room temperature, and says nothing about temperature.
