摘要： A thixotropic molding material includes: a metal body containing Mg as a main component; AlN particles adhering to a surface of the metal body and containing AlN as a main component; and silica particles interposed between the metal body and the AlN particles, having an average particle diameter smaller than an average particle diameter of the AlN particles, and containing a silicon oxide as a main component. A mass fraction of the AlN particles in a total mass of the metal body and the AlN particles is 3.0% or more and 30.0% or less.

摘要： A thixotropically molded product includes: a matrix portion containing Mg as a main component; and a particle portion dispersed in the matrix portion and containing α-Al2O3 as a main component. In a cross section, a total area fraction of the particle portion in a range of 500 μm square around a point at a depth of 1 mm from a surface is 0.5% or more and 30.0% or less.
