Abstract:
The present invention provides a production method for a copper product that minimizes discoloration (the appearance of black spots and the like) of the surface of a copper product, for example, a terminal fracture surface. This production method for a copper product comprises a step in which metal working oil that is obtained from a compound that has no polymerizable carbon-carbon double bonds or polymerizable carbon-carbon triple bonds is applied to the surface of a copper-containing material and the copper-containing material is worked into a desired shape.
