Definitions

  • Patent Literature 4 JP-A-2000-336442
  • the copper alloy wrought material of the present invention will be roughly divided into a first embodiment and a second embodiment, and each described in detail.
  • descriptions that are common with the first embodiment may be omitted.
  • These two embodiments are intended to have special technical features that are the same as or corresponding to each other, and to form a single inventive concept.
  • the term “copper alloy” means that the material does not encompass the conception of shape
  • the terms “copper alloy material” and “copper alloy wrought material” mean that the material encompasses the conception of shape.
  • Ni—Si precipitate Ni 2 Si
  • This Ni—Si precipitate does not contribute much to enhancement of machinability.
  • the sulfide particles thus formed and dispersed be present in the crystals of the matrix at an area ratio of 50% or larger.
  • This embodiment is also similar to the first embodiment, from the viewpoint that S is actively contained in the addition amount described above, which exceeds the general upper-limit amount defined conventionally.
  • the sulfide particles which are compounds to contribute to enhancement of machinability, existing in the crystals of the matrix in the cross-section parallel to the wrought direction, and the aspect ratio of the sulfide particles, and features thereof.
  • the sulfide particles have an effect of finely breaking separating off the chips occurred upon cutting, and thereby machinability is enhanced.
  • the position at which the sulfide particles are present largely affects the ductility and malleability (hot workability and cold workability).
  • the sulfide particles are soft, the sulfide particles may be extended longitudinally depending on the working ratio of hot working or cold working, and are broken and separated, to be dispersed in the matrix.
  • the aspect ratio of the dispersed sulfide particles when the cross-section is observed with an electron microscope, and the length t 1 in the direction perpendicular to the wrought direction is defined to be 1, the aspect ratio is designated as the ratio (t 2 /t 1 ) of the length t 2 of the sulfide particles that are extended in parallel to the wrought direction. If the aspect ratio is greater than 1:100, there is a possibility that the defined content of S may not be satisfied, and thus chips may not be finely broken and separated upon cutting.
  • the tensile strength of each of three samples was measured in accordance with JIS Z 2241, and its average value (MPa) was obtained and shown.
