Copper porous body, copper porous composite member, manufacturing method of copper porous body, and manufacturing method of copper porous composite member

摘要

This copper porous body consists of a sintered compact of several copper fiber, and is a copper porous body which has a skeleton part of a three-dimensional network structure, The copper fiber which forms the said skeleton part consists of copper or a copper alloy, and diameter (R) is It is in the range of 0.01 mm or more and 1.0 mm or less, the ratio L / R of the length L and the diameter R is in the range of 4 or more and 200 or less, and the circularity of the cross section orthogonal to the longitudinal direction is 0.2 It is in the range of 0.9 or more and it is characterized by the porosity being in the range of 50% or more and 95% or less.
