A one-piece, steel, aerosol can formed by a draw and iron process with varying wall thicknesses, including a main body of a first wall thickness, a cone area above of a greater second wall thickness and a curl area above of a third thickness smaller than the second thickness and adapted to fit a standard aerosol valve. A process for shaping the can with the respective wall thickness sections. The process includes necking the can near the top end. The bottom of the can may be supported to maintain a shape during necking. The can interior may be pressurized during necking to resist permanent deformation of the can during necking.
