Abstract: Two-piece metal aerosol container and method of manufacture are provided in accordance with the present invention. A rolled and longitudinally welded cylindrical tube forms the container body, including a cylindrical sidewall and reduced diameter shoulder and neck portions (formed by a sequential necking process), while a separate metal base component is attached via a crimped seam. The open-top end of the container neck portion is curled to receive a manually actuatable dispensing valve assembly. The container is resistant to internal pressures in excess of 311 psi (2150 kPa) and offers increased strength and pressure resistance (compared to a three piece rolled metal aerosol container), while being easy to manufacture and low in cost.
