Coated aluminum material for joining and aluminum resin composite material

Abstract

Provided is a coated aluminum material for joining having an adhesion layer on a surface, and can exert excellent adhesion strength and corrosion resistance performance even under severe use conditions while being chromium-free. Provided is a coated aluminum material capable of producing the coated aluminum material for joining, and an aluminum resin composite material using the coated aluminum material for joining. Disclosed are a coated aluminum material for joining having an adhesion layer on a surface thereof and including a coated aluminum material and a silica-containing film formed on a surface of the aluminum material, the silica-containing film including 0.5 to 35 mass % of a silane coupling agent and having Si and P contents of 2 to 60, and 0.1 to 6.0 mg/m2, respectively, and P/Si mass ratio of P content and Si content of 0.02 to 0.15, and a coated aluminum material capable of producing the coated aluminum material for joining, and an aluminum resin composite material obtained using the coated aluminum material for joining.
