To provide an aluminum molding material and a production method of the aluminum molding material, which presents an achromatic gray color and maintains the texture of the base-material surface of an aluminum base material without being influenced by the hue of the aluminum base material.SOLUTION: An aluminum molding material 1 of the present invention comprises: an aluminum base material 10; an anodic oxide film 20 formed on the base-material surface 10a of the aluminum base material 10; and an electrodeposition coating film 30 formed on the surface 20a of the anodic oxide film 20, the opposite surface side to the surface side 10a of the aluminum base material 10. The electrodeposition coating film 30 includes a white pigment 32 and a black pigment 33. The content of the white pigment 32 in the electrodeposition coating film 30 is between 1.5 mass% and 2.3 mass%. The content of the black pigment 33 in the electrodeposition coating film 30 is between 0.1 mass% and 0.3 mass%.SELECTED DRAWING: Figure 1 【課題】アルミニウム基材の色調の影響を受けることなく、無彩色のグレー色を呈し、アルミニウム基材の基材表面の質感を維持したアルミニウム形材およびアルミニウム形材の製造方法を提供する。【解決手段】本発明のアルミニウム形材１は、アルミニウム基材１０と、アルミニウム基材１０の基材表面１０ａに形成された陽極酸化皮膜２０と、陽極酸化皮膜２０のアルミニウム基材１０とは反対側の面２０ａに形成された電着塗膜３０と、を備え、電着塗膜３０は、白色顔料３２および黒色顔料３３を含み、電着塗膜３０における白色顔料３２の含有量は１．５質量％以上２．３質量％以下、電着塗膜３０における黒色顔料３３の含有量は０．１質量％以上０．３質量％以下である。【選択図】図１
