Metal material surface treatment agents

The present invention aims to provide excellent conductivity, workability, load bearing properties, and surface-treated metal material exhibiting abrasion Re sex can be produced, the surface treatment agent for metal materials having excellent storage stability to. Metal material surface treatment agents of the present invention is obtained by mixing the colloidal silica (A) and an organoalkoxysilane (B), a silicon compound containing an alcohol (C) resulting from the hydrolysis of organoalkoxysilane (B) comprising a dispersion (W), the resin compound (X), and colloidal silica (Y), a lubricant and (Z), an alcohol (C).
